Short answer: the Eseesmart Sliding Glass Door Smart Lock (YL-D208F) is the best smart lock for sliding patio doors overall, the Yale Assure Lock Keypad for Andersen patio doors wins if your door is an Andersen, and the Anweller 2885 Mortise Lock is the one to buy when you need genuine remote app unlock over Wi-Fi. All three install into a standard sliding door mortise rather than a hinged jamb, and all three let you leave keys behind.
A sliding patio door is the one opening most likely to be left unlocked. It sits at the back of the house, it faces a yard where nobody can see it, and the factory latch that came with it is a flimsy hook that a determined person can defeat in a few seconds. Fitting a real lock changes that, and adding electronic entry changes how you use the door every day.
We compared eleven smart locks built for this specific job, checking mortise dimensions, unlock methods, connectivity, weather ratings and the actual review evidence behind each one. The differences matter a great deal here, because most of these products look nearly identical in a listing photo and differ enormously in whether they will actually fit your door.
Before we get into the list, one warning. A smart lock for a sliding patio door is a precision part. You need the door stile thickness, the frame width, and the mortise body dimensions before you order anything, because custom door hardware is awkward to return. Our measurement section below covers exactly what to check, and it is the step that prevents most of the bad reviews in this category.
If you are also rethinking the rest of the patio, our guides to the best patio speakers and the best outdoor speakers for a patio cover the audio side of the same space.

1. Eseesmart Sliding Glass Door Smart Lock: Best Overall for Sliding Patio Doors
Sliding Glass Door Lock, Eseesmart Sliding Door Smart Lock with Fingerprint Code Keypad RFID Card Bluetooth App Key, Electronic Digital Biometric Keyless Entry Patio Door Lock with Handle
5 unlock methods
Fits 22-120mm doors
IP65
Up to 8 months on batteries
250 lb tested
Pros
- Five ways in: fingerprint
- passcode
- app
- RFID card and key
- Up to 300 user profiles
- Reversible handle fits either handing
- IP65 rated and tested to 250 lb
Cons
- Bluetooth only
- so remote unlock needs proximity or a gateway
- Thin written-up customer feedback beyond ratings
This is the lock we ended up recommending most often. It mounts into a standard sliding door mortise, comes with a handle, and offers every entry method we look for: fingerprint, passcode, mobile app, RFID card and a physical key. That last one matters more than it sounds, because fingerprint sensors fail on wet hands, frost and dirty pads, and you want a mechanical fallback.
The fit range is the standout. At 22mm to 120mm of door thickness, it covers almost every residential sliding door, and the reversible handle means you do not need to work out which direction your door slides before you buy. Both the 2885 and 2085 mortise bodies are options, which widens the range of existing hardware it can replace.
Buyers rate it 4.0 from 33 reviews, with 64% giving five stars and only 12% one star. It also ranks in the top 250 for Sliding Door Hardware, which is a decent sign that it has enough real installations behind it to be a safe choice.
How the fingerprint reader handles real weather
The sensor reads quickly in normal conditions, but the outdoor location is the test that matters. This lock is rated IP65, which means it is sealed against dust and water jets, and the manufacturer states an operating range from -13F to 149F. In deep winter you will still want a code or the key rather than a bare finger.
Battery life is stated at up to eight months with a low-power warning, and there is an emergency power bank input for when cells die. Batteries are not the first thing to worry about, but plan a seasonal check anyway.
When to choose something else
Choose this unless you need remote unlock from another country or from a property you do not visit often. It is Bluetooth rather than Wi-Fi, so unlocking from bed, or letting a contractor in while you are at work, means being within range or adding a separate gateway hub. That single limitation is the only reason we did not make it our outright recommendation for every door.
It is also a mortise lock, so it needs a real stile to fit into. If your door is a frameless glass panel with no stile, jump to the no-drill options further down.
2. Yale Assure Lock Keypad for Andersen Patio Doors: Best Brand Name and Voice Control
Yale Assure Lock Keypad for Anderson® Patio Doors Handle with Wi-Fi, Black
Keypad entry
No key cylinder
9V back-up
Wi-Fi and Bluetooth
Alexa, Google, Siri
Pros
- Only lock here from a major lock manufacturer
- One Touch Locking keypad
- 9V back-up keeps it working during an outage
- Works with Alexa
- Google Assistant and Siri
Cons
- 3.6 average with 23% one-star reviews
- Built specifically for Andersen hardware and will not retrofit elsewhere
- Most expensive lock in this roundup
Everything else in this roundup comes from a specialist or generic manufacturer. Yale is the only established lock brand here, and for an Andersen owner that matters more than any spec sheet. This is the factory-style handle set made for Andersen patio doors, with a keypad instead of a key cylinder.
Because there is no cylinder, there is nothing to pick or bump and no key to lose. A tap of the keypad does everything: you tap to enter, tap again to lock. The Yale Access app gives remote monitoring and unlocking over Wi-Fi with a Bluetooth module and a Connect Bridge included in the box.
The warranty reflects the brand: lifetime limited on finish and mechanical operation, one year on the electronics. That split is standard across the industry, but it is worth knowing that the motor and board are the parts that fail, and those are covered for a year.
Check that your door is actually an Andersen
This is the most important thing to confirm before anything else. The lock is designed for Andersen patio door hardware and will not retrofit onto a Pella, a Milgard or a generic door. If your door is not Andersen, skip this section and read the generic mortise reviews instead.
Reviewers report solid results with this lock on Andersen patio doors in particular, and it is one of the few options here that pairs Wi-Fi and Bluetooth with Siri as well as Alexa and Google Assistant. If voice entry at your back door is the goal, this is the clear answer.
Why the 3.6 rating gives us pause
With 55 reviews, this is the most-reviewed lock here, and the average of 3.6 is the second lowest. The distribution explains it: 54% give five stars, but 23% give one star. That pattern usually means fitment or installation problems rather than a bad product, and fitting is the recurring theme in the feedback.
It is also the most expensive lock we reviewed, and for that money many buyers expect a flawless rating. We would only buy it if the door is Andersen and the brand name matters to you.
3. Anweller 2885 Mortise Sliding Door Lock: Best for True Remote App Unlock
Anweller 2885 Mortise Sliding Glass Door Lock, Smart Fingerprint Code Keypad RFID Remote App Electronic Digital Biometric Safety Patio Door Double Hook Mortise Lock Set with Handle
Wi-Fi app unlock
Fingerprint, code, card, key
2885 and 2085 bodies
90-second lockout
8 months battery
Pros
- Real Wi-Fi remote unlock rather than Bluetooth range
- Five unlock methods plus a lockout after repeated failures
- Both 2885 standard and 2085 slim mortise bodies
- 43 reviews is among the higher counts in this niche
Cons
- 3.7 average with 19% one-star reviews
- Mortise compatibility must be checked against your door first
This is the lock we recommend when the real reason for going smart is control. Because it connects over Wi-Fi rather than Bluetooth, you can unlock the patio door from your phone anywhere with a connection, not just when you happen to be standing next to it. That single difference changes who can use the door and when.
The feature list is otherwise familiar: fingerprint, passcode, mobile app, RFID card and a spare key, across doors from 22mm to 120mm thick. It adds a 90-second shutdown after five invalid codes or cards, plus a built-in tamper alarm, which is sensible for a door that faces an unlit yard.
Anweller sells this in both the 2885 standard and 2085 slimmer mortise body, which is the detail most listings bury. The slimmer body matters on older doors with tight internal clearance, so check which one your door takes before ordering.
Why Wi-Fi beats Bluetooth for a rental or guest situation
Bluetooth range on a phone is roughly 30 feet in a typical home, and the signal drops through glass. That is fine when you are on the deck, but of little use when a guest is standing at the door and you are upstairs. Wi-Fi removes the distance problem entirely, which is why this is our pick for a home rented to others.
The trade-off is that the lock depends on a stable home network and a cloud-connected app. If your internet drops, the fingerprint reader, the keypad and the physical key all still work. Only the remote function pauses.
Watch the mortise dimensions before ordering
The manufacturer is explicit that you must verify mortise compatibility with your door, and we would repeat that. Buyers report the Wi-Fi app remote as the standout feature, while compatibility of the mortise with the existing door is the recurring friction point in the reviews.
Measure the internal faceplate width of your existing lock rather than the visible stile, then compare it against the 2885 or 2085 body. Getting this wrong means a return on custom hardware, which is slow.
4. Perfiware LG2315 Biometric Glass Door Lock: Best Drill-Free Lock for Frameless Glass
Smart Glass Door Lock,Perfiware 4in1 Biometric Fingerprint Glass Door Locks LG2315,2024 Drill-Free Keyless Entry Upgraded Door Locks,Great for Office,Home,Hotel,Apartment
Drill-free mount
Fits 10-12mm glass
Fingerprint, code, card, remote
100 users
4AA power
Pros
- Tied for the highest average rating here at 4.5 with 80% five-star ratings
- Drill-free one-piece mounting leaves the glass untouched
- Stores 100 users
- 100 fingerprints
- 100 cards and 10 remotes
- Stainless steel construction
Cons
- Manufacturer states it is not suitable for sliding glass doors
- Only fits 10-12mm glass with a 4-15mm door gap
- Requires 4AA batteries which are not included
This one needs a clear warning before anything else. The manufacturer states that this model is not suitable for sliding glass doors. It is built for frameless push-pull swing glass doors, which are a different category of product entirely.
We include it because so many buyers search for a smart lock for a sliding patio door and end up here, and it is genuinely excellent for the job it was designed for. If you have a frameless interior glass door or a glass office partition, this is a strong pick. If you have a sliding patio door, keep scrolling.
The mounting is the part worth learning from. It is a drill-free one-piece clamp that grips the glass edge, so nothing is drilled and the door stays intact. That approach is the reason no-drill glass locks exist at all, and it is worth understanding before you assume a sliding door can take the same treatment.
Four unlock methods are offered: fingerprint, a 16-digit virtual password, IC card and remote control. The virtual password is designed to be entered as a longer number with decoy digits mixed in, so someone watching over your shoulder sees a wrong code.
Why the 4.5 rating does not make it a sliding door answer
This sits at a 4.5 average across 25 reviews, with 80% five-star and no two- or three-star ratings at all. The electronics are performing well for its intended application.
The fit window is the limit. It handles glass from 10mm to 12mm thick with a two-glass-door gap of 4mm to 15mm, and standard sliding door glass is well outside that. A high rating on the wrong door type is still the wrong door type.
What it tells you about drill-free mounting
Read this section as context for the no-drill options later on. The clamp design grips two panes of glass and a gap between them, which is a geometry a sliding patio door simply does not have. Sliding doors have a track, a stile and a hook, so no-drill sliding door products work on the stile and frame instead.
It also uses four AA batteries, not included, and offers emergency power through a portable charger. Capacity is generous for a household: 100 users with up to three fingerprints each.
5. NGTeco Smart Glass Door Lock: Best No-Drill Pick for Renters and Tenants
NGTeco Smart Glass Door Locks, 5 Unlock Ways Keyless Entry Gate Locks, Remote Control, Fingerprint, IC Card, Password, No Drill Door Locks for Home,Green House,Cabinet,Office
No-drill mount in about 10 minutes
Five unlock methods
1,000 permission sets
4AA, up to 6 months
Pros
- Genuinely screw-free installation in about ten minutes
- Five unlock methods on a budget-tier lock
- Up to 1000 permission sets and 10000 unlock records
- Reviewers confirm fast
- reliable fingerprint and RFID reading
Cons
- Spoken prompts are hard to understand and one buyer could not change the language
- Mounts without screws
- so security is light rather than hardened
- Built for frameless glass rather than a track-mounted sliding door
If you rent, the usual objection to a smart lock is the drilling. This one removes it entirely. The integrated drill-free design installs in roughly ten minutes following the video or graphic guides, with no holes in the door or frame.
It still gives you five unlock methods: fingerprint, password with a virtual or anti-peep option, IC card, remote and a doorbell function. Capacity is unusually generous for a lock at this level, with support for up to 1,000 permission sets and 10,000 unlock records, which matters if you are managing a busy household or a small rental.
Power comes from four AA alkaline batteries for up to six months, with a low-battery reminder and emergency power bank input. Reviewers consistently report that the fingerprint and RFID reading is fast and dependable, and the modern black look blends in better than most of the bulkier locks here.
Be honest about what a screw-free lock actually does
Several buyers explicitly raise this themselves. A lock that mounts without screws can be removed quickly by anyone who knows how, so treat it as convenience and access control rather than a hardened barrier. It is a very good way to give a tenant keyless access, and a poor way to stop a determined intruder.
That is the layered security idea in practice. A no-drill electronic lock handles daily entry, while a mechanical bar or a keeper on the track handles the overnight case. You do not have to choose between them.
The language setting is worth checking
The most common complaint is audio. Multiple buyers report the spoken prompts are difficult to understand because of the accent, and one could not change the language. If you plan to use the keypad mostly by touch, this matters little. If you want voice guidance, listen to it before committing.
Compatibility is the other check: frameless glass doors 100mm to 120mm thick with frames 66mm or wider. A standard track-mounted sliding patio door is outside that range.
6. Dhiedas Fingerprint Sliding Glass Door Lock: Best Slim Mortise for Narrow Frames
Dhiedas Fingerprint Sliding Glass Door Lock, Door Lock with RFID Fingerprint Remote Unlock, Keypad Electronic Digital Biometric Mortise Smart Lock for Double Hook Patio Sliding Door
Slim 2085 mortise under 1 inch
Five unlock methods
300 users
4 AAA, up to 8 months
Pros
- Slim 2085 mortise body under an inch deep
- Remote unlock without Wi-Fi or a gateway via a visitor PIN
- Supports 300 users including 9 administrators
- Emergency USB port plus two physical keys prevent lockouts
Cons
- 3.9 average with 19% one-star reviews
- Requires exact three-dimension measurement before ordering
Older sliding doors, particularly ones from the 1970s, are where a slim mortise lock earns its place. Internal clearance that was adequate then is often tight now, and the 2085 lock body on this model is under an inch deep, one of the more compact bodies we found.
The unusual feature here is gateway-free remote unlock. Instead of needing Wi-Fi or a hub, the lock can be opened remotely when a visitor presses 9 then # on the keypad, and it can generate one-time PIN codes from the app. It is a simpler model of remote access than the Anweller, but it needs no extra hardware.
User capacity is 300 profiles, including 9 administrator accounts, which is plenty for a family and its regular visitors. Batteries are four AAA for up to eight months, with keypad and app low-battery alerts, an emergency USB port and two keys.
Measure three dimensions, not one
This is the strictest fit specification in the roundup, and it is where most of the one-star reviews come from. The lock needs a door thickness between 22mm and 120mm, a frame at least 45mm wide, 10mm of clearance from the frame to the lock edge, and 28mm to the cylinder centre. Get all four before ordering.
Buyers value the slim body and the no-gateway remote unlock, and the tight tolerances are the main source of complaint. Custom door hardware is inconvenient to return, so treat this measurement step as mandatory rather than advisory.
Who should skip it
If you cannot open the panel to check internal clearance, or if your frame measures under 45mm, this lock is not for you and neither is any other mortise body. In that case, move to the no-drill surface-mounted options or plan on replacing the door hardware entirely.
There is also no stated IP weather rating for this model, which matters if your patio door is fully exposed rather than under a deep overhang.
7. eLinkSmart Ultra-Slim Patio Lock: Best for App Control on the Tuya Ecosystem
eLinkSmart Sliding Glass Patio Door Smart Lock, Ultra-Slim Mortise Lock – Keyless Entry with Fingerprint, Keypad, RFID & Biometric, Tuya App Control Waterproof for Home, Apartment (Black)
32mm slim mortise
6-in-1 unlocking
AES-256 encryption
IP65
4 AAA for 8 months
Pros
- One of the two narrowest lock bodies here at a claimed 32mm
- Six unlocking methods including logged temporary guest passwords
- AES-256 encryption and anti-spoofing fingerprint with a 90-second lockout
Cons
- Only 6 reviews
- so there is very little independent feedback
- Runs on the Tuya app ecosystem rather than a maker's own app
- 4 AAA batteries not included
This lock carries the most detailed specification sheet in the roundup, and also the least real-world evidence behind it. That combination deserves a straight recommendation: on paper it is one of the stronger ultra-slim options here, but you are buying on specifications rather than on history.
The 32mm, or 1.25 inch, lock body is the number that matters. It fits frames 35mm or wider and doors thicker than 22mm, a range that covers more frames than the competing slim mortise locks here. On a narrow frame that has resisted other locks, that difference decides the outcome.
Six-in-one unlocking covers fingerprint, password, app, RFID card, backup key and temporary guest passwords, with entry tracking logged in the app. Fingerprint recognition is described as AI-based to reject fake prints, and data is AES-256 encrypted.
What the Tuya app means for you
The lock runs on Tuya rather than a manufacturer-specific app. That is a genuine advantage if your home is already Tuya-based, because it joins routines alongside your lights, cameras and blinds. It is a drawback if you run HomeKit, SmartThings or Home Assistant, since you would be adding a second app ecosystem.
Temporary guest passwords with entry tracking are the feature that rental hosts care about, and they work here. Reviewers with a mixed smart home generally prefer a lock that speaks the platform they already use.
Six reviews is not enough to lean on
The 3.9 average comes from just 6 reviews, split 73% five-star to 27% one-star. Buyers should expect thin real-world testing at this volume, and any long-term problem with the fingerprint reader or the app is unlikely to have surfaced among half a dozen owners.
On paper the lock is IP65 waterproof aluminium, rated -13F to 149F and tested to 15,000 cycles, with an 8-month battery life, Type-C emergency charging and a 24-month warranty. We would pair it with a mechanical keeper rather than trust it alone.
8. Saluaqui Slim Smart Patio Door Lock: Best for Fast Fingerprint Entry
Saluaqui Slim Smart Door Lock, Keyless Entry Door Lock, Sliding Smart Patio Door Handle Set, Bluetooth Digital Keypad Fingerprint Smart Mortise Patio Door Lock for Home Glass Sliding Door
0.3-second fingerprint
Five unlock methods
IP65 alloy body
40-80mm doors
100 fingerprints
Pros
- Perfect 5.0 rating from the 2 reviews it has
- 0.3-second fingerprint recognition
- Zinc and aluminum alloy body with IP65 weather sealing
- Full mounting hardware kit in the box
Cons
- Only 2 reviews
- so the 5.0 rating means very little
- 40-80mm door thickness is the narrowest range here
- Very low sales rank in Tools and Home Improvement
When people ask for the fastest way through a patio door, this lock claims a 0.3-second fingerprint read, among the quickest figures quoted here. Five unlock methods are supported: fingerprint, password, card, key and the TT LOCK app.
The body is zinc and aluminum alloy with IP65 weather sealing, and the storage is generous at 100 fingerprints, 100 passwords and 100 cards. All mounting hardware is included, along with two keys, two IC cards, a cylinder and the rods and screws needed for a mortise installation.
It also lists SmartThings among its controller types, which is unusual for a lock at this level and makes it worth a look if you already run that platform.
The 40-80mm door thickness window is the deciding factor
This is the tightest door thickness range of any lock here. If your sliding door stile measures outside 40mm to 80mm, this lock will not fit regardless of how good the electronics are. Measure first, then decide.
Many modern sliding doors use wider stiles, and older aluminium doors can fall below 40mm. This is exactly the fitment uncertainty that drives returns in this category, and it takes five minutes to avoid it.
A perfect rating built on two reviews
Both existing reviews are five stars, giving a 5.0 average. That figure carries almost no evidential weight, and we would treat it accordingly. The listing also sits very low in Tools and Home Improvement sales rank, which means a short sales history and limited long-term owner feedback.
On paper this is a capable lock with fast biometrics and good weather sealing. The risk is not the specification, it is the absence of people who have used it long enough to report a problem with it.
9. Perfiware LG75TY Sliding Door Lock: Best Kit for Framed Sliding Glass Doors
Perfiware Sliding Glass Door Lock LG75TY with APP,Smart Fingerprint Keypad Pin Screen Sliding Door Locks,Keyless Safety Lock for Sliding Door,Great for Office,Hotel,Apartment,Patio,Barn,Front Door
Main and sub lock kit
Fits framed sliding doors
Five unlock methods
Auto-lock
4AA power
Pros
- One of the few options that fits a framed sliding door rather than frameless glass
- Kit includes a main lock
- sub lock and side strip for single-sided installs
- Five unlock methods with app
- doorbell button and temporary passwords
- Stainless steel high load construction
Cons
- A 3.3 average with 24% one-star reviews
- Needs a frame wider than 2.87 inches and 4AA batteries not included
- Only 4 reviews
- so there is very little owner feedback
Most sliding door smart locks assume a frameless glass panel. This one is built the other way around, for a framed sliding door, and the kit reflects that: a main lock, a sub lock for double-sided installs, and a side strip for single-sided installations.
Five unlock methods are provided: app, fingerprint, a 16-digit virtual password, IC card and remote control. The app adds a doorbell button for visitors, remote unlock and time-limited temporary passwords, and the lock auto-locks when the door closes or can be set to a constant open mode.
Storage covers up to 100 users and 100 fingerprints with three fingerprints per user, 100 cards and 10 programmed remotes. It is a stainless steel build rated for high load on framed glass or wooden sliding doors and double action doors.
Check the frame width before you commit
The lock panel measures 7.28 inches long by 2.87 inches wide, and the manufacturer requires a door frame wider than 2.87 inches. That is a fairly generous requirement and rules out a lot of narrower aluminium sliders. Model LG2375 is identical, so listings are sometimes duplicated.
Batteries are four AA, not included, with emergency power through a portable charger. Nothing else in the box beyond the locks, side strip, one IC card, remote and instructions.
The rating is among the weakest here
At 3.3 from 4 reviews, this is tied for the lowest average here, with a wide spread of 29% five-star down to 24% one-star. The sample is far too small to draw a conclusion, and the 42% one-star share on the Swokely below shows how noisy very small samples can be.
What we will say is that if your door is a framed sliding door and the other options here explicitly exclude that format, this is one of very few kits designed for it. Check the frame width, keep a key handy, and set a calendar reminder for batteries.
10. Giztud Sliding Door Smart Lock: Best for Face and Palm Vein Entry
Sliding Door Smart Lock Keyless Entry Sliding Door Lock with Fingerprint Code IC Card Keypad Digital Key APP Remote Replacment Slim Thin Frame Biometric Fingerprint Door Locks
7-in-1 access including face and palm vein
5000mAh rechargeable battery
No-drill mount
Multi-user profiles
Pros
- Widest unlock repertoire here at seven methods including face recognition and palm vein
- Perfect 5.0 rating across 8 reviews with no ratings below five stars
- Rechargeable 5000mAh battery
- so no disposable cells to replace
- No-drill mounting that reviewers say preserves the glass
Cons
- Bulky housing that several reviewers call large and heavy for a slim frame
- Glass thickness must be measured before ordering
- Bluetooth only with no Wi-Fi gateway remote unlock
This is the only lock here with biometric options beyond a fingerprint. It offers seven ways in: face recognition, a fingerprint scanner, palm vein detection, an IC card reader, app control and a traditional key backup. For a household where fingerprints are unreliable, gloves or wet hands are constant, that is a real answer.
It is also the only lock in the roundup with a rechargeable battery rather than disposable cells. A 5000mAh pack means you are not opening the door to swap AA batteries twice a year in cold weather, which is a persistent complaint in smart lock reviews.
The mounting system is no-drill for a sliding glass door, and reviewers say it preserves the glass while still seating securely. Multi-user profiles with customisable permissions cover family and guest access, and a heavy duty auto-locking mechanism handles the latch.
Face and palm vein entry in practice
Owners cite fast, accurate face and fingerprint reading, and the biometric variety is the reason to choose this over a conventional keypad lock. Palm vein and face recognition both work without a finger on a sensor, which helps with children, older adults and anyone carrying bags.
None of the reviews describe a false acceptance or a security problem with the biometric side. As with all biometric systems, treat it as one of several entry options rather than the only one, which is how the lock is designed to work.
Size is the consistent complaint
Several buyers note the housing is bulky and better suited to a larger door such as a sliding patio door than a small glass panel. That is an odd complaint in this roundup, where a patio door is exactly the target, but it does matter if you have a narrow sidelight.
Measure your glass thickness and frame before ordering, and note that the lock is Bluetooth only, so there is no Wi-Fi gateway remote unlock. The 8 reviews are all five-star but come from a short window in 2026, so treat the perfect score as encouraging rather than conclusive.
11. Swokely Slim Smart Lock with Camera: Best for Built-In Camera Monitoring
Swokely Slim Smart Lock for Sliding Glass Door, Waterproof Keyless Smart Mortise Lock with Camera, WiFi Keypad Aluminum Fingerprint Door Lock with Handle – 5 Unlocking Methods for 40-120mm Door
Built-in camera
Wi-Fi app control
5 unlock methods
40mm slim panel
4 AAA, 6 months
Pros
- One of the few here with a built-in camera inside a slim sliding door mortise body
- Wi-Fi app connectivity alongside fingerprint
- card
- password and key
- Narrow 40mm panel fits slim aluminum glass door edges
- Waterproof stainless steel with alarm and voice guidance
Cons
- A 3.3 average with 42% one-star reviews
- Only 5 reviews
- so the low score rests on a very small sample
- Sits above most other generic mortise locks here despite the rating
A camera inside the lock body is unusual in this category, and it is the reason to look at this model. If you want to see who is at the back door without installing a separate camera pointed at a reflective glass panel, this is one of the few options that does both jobs in one piece of hardware.
Five unlock methods are supported: fingerprint, card, password, app and key. The semiconductor fingerprint sensor is designed to reject duplicate prints, with one-second unlock and automatic engagement once you are inside. Four AAA batteries are rated for up to six months.
Fit is handled by a 3585 lock body for doors 40mm to 120mm thick, with a narrow 40mm panel and a 4cm edge for aluminum alloy glass doors. Construction is waterproof stainless steel with an intelligent alarm, low battery reminder and voice guidance.
The rating split is unusually wide
At 3.3 from 5 reviews, this is tied for the lowest average in the roundup, but look at the spread: 58% five-star against 42% one-star. That is not a mediocre product with a bad day, it is a product where owners either get one they like or one that fails them outright, with nothing in between.
With a sample this small we cannot tell which failure mode dominates, and that is the reason we place it last rather than calling it bad. The integrated camera and Wi-Fi are genuinely unique here, and reliability is the open question.
Value versus the alternatives
Its price sits above most of the other generic mortise locks we reviewed while carrying a weak rating, which is a hard combination to justify. If the camera is the deciding feature for you, it may be worth it. If you only need keyless entry, the Eseesmart or Anweller give you more proven ground for less.
It is also worth noting that a lock camera needs power and network access, and four AA batteries is a tight power budget for continuous video. Check what the camera actually records before you commit.
How to Choose a Smart Lock for a Sliding Patio Door
Fitment decides almost everything. Every other feature on these locks is secondary to whether the mortise body physically fits your door, and the retailers and manufacturers all make the same point: measure before you order.
Measure the door before you order
You need four numbers. The stile thickness where the lock will sit, the width of the internal faceplate opening, the distance from the frame edge to the lock body, and the clearance available inside the panel once the glass is removed. Add the distance to the cylinder centre if the lock has one.
The locks in this roundup fit between 22mm and 120mm of stile thickness, with one model limited to 40mm to 80mm and two drill-free models with far narrower glass ranges. That spread is the entire difference between a good purchase and a return.
Older aluminium doors from the 1970s often fall below 45mm in frame width, which is why ultra-slim mortise bodies exist in the first place. Home improvement forums carry a recurring thread on exactly this problem.
Mortise body versus surface mount
A mortise lock sits inside the door stile and engages a keeper plate in the frame. It looks like factory hardware, it is the strongest option, and it requires removing the panel and often glass. Most of the locks here are mortise.
A surface-mount lock clamps to the outside of the door and pulls a hook into a surface keeper. It installs without opening the door, which is the renter-friendly path, but it looks bulkier and offers less resistance to a determined attacker. The no-drill models in this roundup are of this type, and buyers rightly treat them as access control rather than a security barrier.
Bluetooth, Wi-Fi, Z-Wave, Thread and Matter explained
Bluetooth connects your phone directly and works within roughly 30 feet, which suits a lock you use from the deck. It is the simplest option and needs no hub, but it cannot let you unlock from another city.
Wi-Fi connects through your router and gives real remote unlock anywhere, at the cost of a cloud-connected app and a dependency on your internet connection. Two locks here use Wi-Fi, and that is the feature to prioritise if you manage a rental or want to admit a guest remotely.
Z-Wave Plus and Thread with Matter are the choices for a local smart home. Z-Wave runs on a mesh network through a hub and has been the standard for SmartThings and Home Assistant users for years. Thread runs low power over the same radio spectrum and is designed to carry Matter, the newer common standard that lets one lock work across ecosystems. None of the eleven locks here support Z-Wave, Thread or Matter, so if your home is built around one of those, expect to wait or plan on a hub-based alternative.
Unlock methods that matter day to day
Fingerprint is fastest but fails on wet hands, frost and dirty pads. Keypad is the most reliable in any weather and needs no phone. A physical key is the fallback that keeps you out of a lockout, and only some models include one.
RFID card access suits a household with children who cannot remember a code. Temporary codes and one-time PINs are what rental hosts and short-stay guests need. Two models here generate one-time codes from the app, and one supports up to 300 or even 1,000 permission sets for heavier user management.
Door brand compatibility notes
The Yale in this roundup is built for Andersen patio door hardware specifically and will not retrofit onto other brands. For Pella, Milgard or generic doors, the generic mortise locks are the relevant group, and the mortise body dimensions matter more than the brand name.
Where you can match an OEM part number to the door manufacturer, do it, because it removes fitment guesswork entirely. Where you cannot, measure rather than assume.
Installation, weather and battery planning
Mortise installation means removing the interior panel, lifting glass if needed, and cutting or reusing the existing faceplate. Budget an afternoon the first time, and expect to pay a locksmith if you have never done it. Drill-free installs take about ten minutes by the manufacturer’s own estimate.
Weather resistance is stated as IP65 on several models, covering dust and water jets, with operating ranges quoted from -13F to 149F on the most fully specified units. One model in this roundup states no IP rating, which matters more if your door sits in an exposed yard.
On batteries, stated figures range from six to eight months on four AA or AAA cells, and one option uses a 5000mAh rechargeable pack instead. Add a reminder to check every season, because cold weather shortens battery life and a flat battery on an exterior door is an emergency. Use the keypad, fingerprint or key while the app reports low, rather than waiting for the failure.
Frequently Asked Questions
What is the best electronic lock for a sliding patio door?
The Eseesmart Sliding Glass Door Smart Lock is our best overall pick because it offers five unlock methods, fits stile thicknesses from 22mm to 120mm, carries an IP65 weather rating and supports up to 300 user profiles. For an Andersen door specifically, the Yale Assure Lock Keypad is the stronger choice. For remote unlock from anywhere over Wi-Fi, choose the Anweller 2885 Mortise Lock.
Can I put a smart lock on a sliding glass door?
Yes, but only if you buy a lock designed for sliding doors rather than a standard deadbolt. Sliding doors need either a mortise lock with a hook latch that engages a keeper plate in the frame, or a surface-mounted clamp that pulls a hook into an external keeper. Measure your stile thickness and frame width before ordering, because generic mortise bodies vary widely in size.
What is the best automatic lock for a sliding glass door?
For an automatic lock that relocks itself, the Eseesmart and Anweller mortise locks both handle auto-lock behaviour, and the Perfiware LG75TY kit is built specifically for framed sliding doors with a main and sub lock. Pair any automatic lock with a mechanical bar or keeper on the track, since an electronic lock that loses power should not be the only thing between a patio door and the yard.
What is the best lock for a patio sliding door?
For most homeowners the answer is a fingerprint and keypad mortise lock that fits their door, such as the Eseesmart model. Renters should choose a no-drill surface mount instead. Homeowners with an Andersen door should choose the Yale keypad. The key decision is fitment, so measure stile thickness and frame width before choosing any brand.
Are smart locks for sliding doors secure?
A quality mortise smart lock with a hook latch is considerably stronger than the factory latch most patio doors ship with. Surface-mounted, screw-free locks are weaker and can be removed quickly by someone who knows how, so treat them as keyless access control rather than a security barrier. The most reliable approach layers an electronic lock with a mechanical bar, keeper or track lock that works with no power at all.
Do smart locks work on older sliding glass doors?
Often yes, but older doors need extra care. Frames from the 1970s can measure under 45mm wide and have tight internal clearance, so ultra-slim mortise bodies such as the 32mm eLinkSmart model or the slim 2085 body used by the Dhiedas lock are the safer bet. If the frame is too narrow for any mortise body, a surface-mounted clamp is the practical option.
Our Final Verdict on the Best Smart Locks for Sliding Patio Doors in 2026
The best smart locks for sliding patio doors come down to fitment first and features second. For most doors, the Eseesmart Sliding Glass Door Smart Lock is the pick: five unlock methods, the widest stile thickness range, IP65 sealing and 33 reviews with a 4.0 average. Andersen owners should choose the Yale Assure Lock Keypad for voice control and brand support, and anyone who needs genuine remote unlock should pick the Anweller 2885.
Renters should not drill, which makes the no-drill surface mounts the sensible category. Measure your stile thickness, frame width and internal clearance first, in that order, and pair whatever you choose with a mechanical keeper.
