Yes, you can put a smart lock on a sliding door, but only with a lock built for sliding doors. A standard deadbolt will not physically fit the slim stile, and a keypad door handle meant for a swinging front door will not bridge the gap between the sliding panel and the fixed jamb. What you need is a slim mortise or surface-mount body with a double hook that catches both stiles so the panel cannot be lifted off its rollers.
That is the single most common mistake in this category, and it is why most search results fill the page with locks that cannot be installed on the door in front of you. We read the fit specifications on all eight options below, checked what buyers report after living with them, and matched each one to the door type it actually serves. The shortlist covers Andersen-branded patio doors, aluminum and glass sliders, rental properties, and frameless glass where drilling is not allowed.
A note on how we put this together: every thickness range, stile minimum and battery figure below comes from the manufacturer listing, and every rating and complaint comes from the customer reviews on that listing. We did not lab-test these locks, so treat the fit numbers as the thing to verify with a tape measure before you order rather than as a promise. Last updated for 2026.

This is the only lock in our list sold by an established lock manufacturer, and that matters more than the spec sheet. The box contains the door lock, mounting hardware, levers, the Bluetooth module and the Connect Bridge, so you are not hunting for a handle to pair with it. The model number is YRM276-CB1-BLK and it is finished in black alloy steel.
Entry is keypad or app, with one-touch locking that lets you secure the door by tapping the panel rather than turning a handle. There is no cylinder at all, so there is no key to lose and nothing to pick. Buyers also like the 9V battery contact, which lets you energise the lock from a household battery if the internal cells die.
The catch is compatibility. This is a patio-door variant built for Andersen-branded sliding doors, not a generic slider, so confirm your door brand before buying. The 3.6 average rating and a one-star share of about 23% point to install friction rather than hardware failure, mostly fit and connectivity rather than the mechanism itself.
The lever and handle set also adds visual bulk. On a slim contemporary slider the hardware reads as heavier than the door, which is the main complaint we saw from owners happy with the electronics.
Check your door brand before anything else
If your slider carries an Andersen nameplate, this is the most straightforward path on the list because the fit is engineered for that frame. Buy the handle-and-lock bundle rather than the bare lock if you are replacing both, since the two are dimensioned as a set.
If your slider is unbranded, an aftermarket aluminum or vinyl frame, keep reading. The remaining seven options are all built for generic frames, and three of them cover thickness ranges wide enough to swallow almost anything.
Where this one falls short
The 55-review sample is thin for a product that people expect to run for a decade outdoors, and the warranty splits: lifetime limited on finish and mechanical operation, one year on electronics. Remote unlock depends on the Connect Bridge staying paired to your network, and if it drops you are left with the keypad only.
Rating of 3.6 also sits below what you would expect from a major brand. Treat it as a capable, well-supported lock with a compatibility ceiling rather than a flawless one.

2. JNZCH Sliding Door Fingerprint Lock – narrowest fit and the strongest weather sealing
Sliding Door Smart Lock, Sliding Glass Door Lock with Fingerprint
- Fingerprint IC card PIN app and key
- Fits 30-55mm doors
- IP65 rated -13F to 131F
- 4 AA up to 6 months
Pros
- Fast fingerprint reads with green and red status lights
- Five unlock paths including two IC cards
- Peek-proof PIN lets you add decoy digits
- IP65 sealing for covered outdoor sliders
Cons
- Several reports of the handle opening from outside when locked
- No printed instructions in the box
- Fit starts at 30mm so very slim doors fail
- Needs a 2.4 GHz Wi-Fi band for setup

This is the narrow-body option for thin aluminum and glass sliders. The lock fits door thickness from 1-3/16 inch to 2-3/16 inch, which is 30mm to 55mm, and the square shaft can be trimmed from 3-5/32 inch so you can shorten the spindle to match a shallow stile. A cutting template is included in the box, which saves a trip to the hardware store.
Five ways in: fingerprint, IC card, PIN, the Tuya app and a mechanical key. Two IC cards and two keys come with it. The peek-proof PIN is the sleeper feature: you can enter random digits before or after your real code so someone watching over your shoulder at the door sees nothing useful.
Weather sealing is genuinely strong here. The lock is rated IP65 for dust and water and carries a stated operating range of -13°F to 131°F, and it runs on four AA cells for up to six months with a USB-C input for emergency jump-start.
The security complaint dominates the reviews, so read it carefully: several buyers report the handle can be operated from outside even in the locked position. Multiple reviews point to the same cause and the same remedy, which is flipping the orientation of the connecting square spindle during installation.
There is no printed manual in the box, so budget time for the online guide. Setup also requires a 2.4 GHz band, which will not connect on a 5 GHz-only network.
When this slim lock makes sense
Choose it when your door is on the thinner end of the range and you want fingerprint entry without a key cylinder. The IP65 rating is a real advantage on a covered outdoor patio slider that takes wind-driven rain.
The trimmable spindle is what makes it work on shallow stiles that a full-width lock body would overhang. That single detail resolves the most common fit complaint we saw across this category.
When to skip it
With a 3.2 average and a 27% one-star share, this lock has the weakest rating of the eight. If outside handle operation is a concern you cannot verify yourself after install, choose a pick with a stronger consensus.
It also caps out at 55mm of thickness. A thick wooden patio door with a deep frame is outside its range entirely, and the 30mm floor excludes the very slim glass doors that motivate most no-drill searches.

3. Anweller 2885 Mortise Sliding Lock – the widest thickness range
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
- Fingerprint passcode app RFID and key
- 22-120mm thickness
- 2085 or 2885 mortise
- Up to 8 months battery
Pros
- Widest thickness range on the list
- Tamper alarm plus 90-second lockout after five bad entries
- Two mortise bodies so you can pick slim or standard
- Power bank input when the battery dies
Cons
- 3.7 average with 19% one-star reviews
- Needs a stile at least 45mm wide
- Wi-Fi remote unlock depends on app and router reliability
- Mortise compatibility must be verified first

If your door is an unusual size, this is the one to measure twice and buy once. It fits door thickness from 13/16 inch to 4-3/4 inch, which is 22mm to 120mm, and it is available as the 2885 standard mortise with the 2085 slimmer mortise offered as a variant. Owners pick the body that matches their existing cut-out.
Five unlock paths again: fingerprint, passcode, app over Wi-Fi, RFID card and a spare key. Two RFID cards and two mechanical keys are included, along with a screwdriver and manual. The unit itself weighs 3.7 pounds and measures 12.6 by 1.4 by 2.2 inches.
The security behaviour is the best-specified here. The lock shuts down for 90 seconds after five invalid code or RFID attempts, and a tamper alarm triggers when the door is forced. Battery life is stated at up to eight months with a low-battery reminder, and a power bank can be plugged in when the cells run out.
Fit is the entire challenge. The manufacturer asks you to confirm mortise compatibility before purchase and specifies frames at least 1.8 inch, or 45mm, wide. On a narrow glass stile that measurement is where most installs fail.
A 12-month warranty with lifetime technical support and replacement inside 12 months is included, which is a reasonable safety net for a first-time installer working on glass.
Where the 22-120mm range earns its keep
That span covers everything from a slim aluminum slider to a thick wooden patio frame, so it removes the guesswork that forces you into a brand-specific lock. For a house with two different sliders, one model can cover both.
Choosing between the 2885 and 2085 bodies is the decision that determines whether the lock fits at all. Measure the existing mortise pocket and the stile width before ordering, and pick the slimmer 2085 if the frame is tight.
The drawbacks that matter
Remote unlock runs over plain Wi-Fi through a mobile app, so it inherits the reliability of your router and the vendor’s cloud. If you already run SmartThings or Home Assistant, expect this lock to sit outside that ecosystem rather than join it.
Buyers also note that fitting a mortise body by hand is not realistic on every stile. If your frame is thin or you have drilled nothing before, budget for a locksmith.

4. Eseesmart Sliding Glass Door Lock – the IP65-rated all-rounder
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
- IP65 waterproof rated to -13F
- 22-120mm thickness
- 300 user profiles
- Bluetooth app control
Pros
- Highest average rating among the sliding-door models at 4.0
- IP65 sealing rated down to -13F
- Rated for 15000 cycles and a 250 lb force test
- Reversible handle and 24-month warranty
Cons
- Bluetooth only so remote unlock depends on proximity
- Only 33 reviews for a track record
- Mortise compatibility still needs checking
- 17% of reviews sit at three stars

This is the pick to shortlist first if owner satisfaction is your main filter among the true sliding-door locks. It holds a 4.0 average with 64% of reviews at five stars, and it is also available in 2085 and 2885 mortise bodies, so it fits the same doors as the Anweller but with a better return rate from owners.
Five unlock options cover fingerprint, passcode, mobile app, RFID card and key, with capacity for up to 300 users. Two RFID cards and two mechanical keys are included. The handle is reversible, so the same unit covers a door that opens in either direction.
The durability figures are unusually specific for this category. The lock is rated IP65 for waterproofing, specified from -13°F to 149°F, tested for 15,000 lock cycles and put through a 250 lb weight test. Battery life is stated at up to eight months with a low-power warning, and a power bank is accepted for emergencies.
Fit covers 13/16 inch to 4-3/4 inch of door thickness, 22mm to 120mm, and the body measures 1.37 by 2.16 by 12.6 inches at 3.7 pounds.
The warranty is the longest in this comparison at 24 months, with lifetime technical support and a 12-month replacement or refund service behind it.
What you give up for the rating
Connectivity is Bluetooth only. That means app control and remote unlock work at close range rather than from across town, which is fine for daily use but not for admitting a guest from the airport. The Bluetooth range is a real convenience for a family walking up with groceries.
Setup is simpler for the same reason. No bridge, no separate Wi-Fi credentials, no hub sitting on a shelf.
Is it right for your door
Pick it when the door sits anywhere in the 22-120mm band and you want cold-weather and rain performance you can point to on a spec sheet. Reviewers report the sealing holding up on outdoor installations.
Skip it if you need internet-scale remote unlock, or if your stile is under 45mm wide and the mortise body will not fit. Thirty-three reviews is a decent sample but not a decade of data.

5. Perfiware LG2315 Drill-Free Lock – for frameless glass, not sliding tracks

We are including this one with a clear warning because it ranks high and gets bought for the wrong door. The manufacturer states the LG2315 is not suitable for sliding glass doors: it is designed for push-pull frameless glass doors and double-acting frameless glass doors. If your door runs in a track, stop reading and skip this pick.
Where it does work, the design is genuinely clever. A drill-free one-piece construction clamps to the glass without cutting into it, which is exactly the solution for landlords, HOAs and warranty terms that prohibit drilling. Installation is quick and reversible.
Who it suits
A frameless office door, a shop front, an apartment entrance with a glass swing door. It stores up to 100 users, 100 fingerprints and 100 cards, with three fingerprints allowed per user, which is enough for a small business or a busy family.
Unlock methods are fingerprint, a 16-digit virtual password, IC card or remote, and it auto-locks on door closure with a constant-open mode for high-traffic hours.
The hard limits
Fit is narrow and unforgiving: 10mm to 12mm of glass thickness, with a 4mm to 15mm gap between the double doors. The panel is 7.28 inches on its long side and 0.86 inches thick. Anything outside those numbers will not mount.
The evidence base is also the thinnest here at 25 reviews, and the four AA batteries are not included.

6. Dhiedas Slim Mortise Lock – built for rental turnover
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
- Gateway-free remote unlock
- 22-120mm thickness
- Slim 2085 or 2885 body
- 4 AAA up to 8 months
Pros
- Remote unlock works with no Wi-Fi and no gateway
- 300 users including nine administrators
- Slim mortise body fits stiles 45mm or wider
- Eight months on AAA with keypad and app alerts
Cons
- Only 18 reviews so long-term reliability is unproven
- 19% one-star reviews suggest fit and finish inconsistency
- USB port gives temporary power only
- AAA cells are not included

This is the one to look at if you run a short-term rental. The distinguishing feature is remote unlock that needs no Wi-Fi and no gateway: you dial 9 then # on the keypad and the door opens from anywhere a phone signal or a call can reach it. That removes the single point of failure that takes other app locks offline.
Capacity suits a busy property. It supports 300 users including nine administrator profiles, so you can issue a separate code or fingerprint to every guest without touching the admin account.
Fit covers 13/16 inch to 4-3/4 inch of door thickness, 22mm to 120mm, on frames 1.8 inch or wider. The installation needs 10mm of clearance from the frame to the lock edge and 28mm to the cylinder centre, so measure before drilling.
Five unlock paths again: app, RFID, fingerprint, passcode and two backup keys. The lock shuts down for 90 seconds after five invalid code or RFID attempts, and the tamper alarm covers forced entry.
Power comes from four 1.5V AAA cells for up to eight months with low-battery alerts on the keypad and in the app. The USB port supplies temporary unlock power only, so it will not recharge the unit.
Why rental hosts like it
The 9-then-# trick is the headline.
Nine administrator profiles also mean you can hand a cleaner or a property manager their own access without sharing the master account.
Where it is thin
Eighteen reviews is not much of a reliability record, and 19% of them sit at one star. Owners point to fit and finish inconsistency rather than electronics failure, which again puts measurement at the centre of a clean install.
AAA cells are less common than AA, so keep a spare set in the house. A 12-month warranty with lifetime support is included.

- Stiff mechanism and dated on-screen graphics

This is the budget entry, and the arithmetic works if your door matches its range. The compatibility note specifies frameless glass doors of 100mm to 120mm thickness with a door frame width of 66mm or more, which is a much narrower band than the sliding-door locks above.
It fits frameless swinging glass doors rather than sliding tracks, so treat it as an adjacent option for gate, cabinet, greenhouse and office doors as well as home entry. Several buyers bought it for those secondary doors and rate it highly.
Five unlock paths are available: fingerprint, password including a virtual anti-peep code, IC card, remote control and a doorbell function. Permission management covers up to 1,000 permission sets and 10,000 unlock records, which is generous for a lock at this price.
Installation is drill-free and takes roughly ten minutes with no damage to the door. Power comes from four AA alkaline batteries for up to six months, with rechargeable AA supported and an emergency power bank input.
Where the value shows up
The no-drill mounting is the reason to consider it. If drilling your glass is prohibited, or you want to move the lock between doors later, a clamp-style mount solves a problem a mortise body cannot.
Rechargeable AA support is a quiet cost saving over a year of daily use, and the doorbell function is a small extra that is useful on a secondary door.
The honest caveats
Several reviewers doubt it as a real security lock outdoors, particularly in humid or exposed locations. We would keep it on interior or secondary doors rather than as your sole entry control.
The voice prompts have a Chinese accent and reviewers report they could not change the language, and the mechanism feels stiff with dated on-screen graphics. Fifteen reviews is a thin sample.

8. eLinkSmart Slim WiFi Lock – no hub required
eLinkSmart Slim Keypad Door Lock Built-in WiFi Fingerprint Keyless Entry Mortise Smart Lock for Sliding Patio Glass Door, 2885 Hook Latch, Fits 22–110mm (0.87″-4.33″) Door Thickness, Tuya App
- Built-in Wi-Fi gateway
- 36mm slim body
- 22-110mm with adapters
- 4 AAA up to 12 months
Pros
- Narrowest lock body here at 36mm with a 40mm minimum frame width
- Built-in Wi-Fi gateway connects to the Tuya app with no extra hub
- Five adapter sets in the box cover 22-110mm
- All-steel dual hook latch resists forced entry
Cons
- Several buyers report it does not fit standard sliding patio doors
- App pairing failures block fingerprint and RFID setup
- No printed instructions and a wrong template in some boxes
- Stiff mechanism and the hook does not retract automatically
We earn a commission, at no additional cost to you. CERTAIN CONTENT THAT APPEARS ON THIS SITE COMES FROM AMAZON. THIS CONTENT IS PROVIDED 'AS IS' AND IS SUBJECT TO CHANGE OR REMOVAL AT ANY TIME.
The idea here is the cleanest of the group. The Wi-Fi gateway is built into the lock body, so it joins the Tuya app directly without a separate bridge or hub on the shelf. At 36mm the lock body is also the narrowest here, with a 40mm minimum door frame width, which makes it a candidate for tight glass stiles.
Five unlock methods cover fingerprint, password, NFC card, app remote and key. The box includes five installation screw adapter sets covering 22-30mm, 30-45mm, 45-60mm, 60-80mm and 80-110mm of door thickness, so the whole 22-110mm span is covered without hunting for parts.
The latch is the piece worth noting. An all-steel dual hook latch resists forced entry better than a standard latch, and the handle is reversible for sliding doors that open in either direction. Battery life is stated at up to 12 months on four AAA cells, the longest claim in this comparison.
One-time, temporary and scheduled access codes are supported in the app, which is the feature rental hosts and family members will use most. Installation is no-drill and takes 10 to 15 minutes with a screwdriver.
Why the design is right
Eliminating the hub removes the most common complaint about app locks, which is a separate box to power, pair and maintain. It also removes a per-device cost from the setup.
The included adapter set means you can commit to the purchase before you have measured precisely, then adjust on install day.
Why the reviews are thin
With 13 reviews and a 3.3 average, this is the least proven option here. Buyers praise the concept and the build while reporting compatibility failures with standard sliding patio doors and app pairing failures that block fingerprint and RFID setup entirely.
One reviewer received the wrong cut-out template and no printed directions, and several describe a stiff mechanism where the hook does not retract automatically when the knob is turned. Support is a 30-day return with a 180-day free exchange.

How to measure your sliding door before you buy
Almost every failed install in this category comes down to four numbers, and all four take about five minutes with a tape measure. Get them before you choose a lock, not after.
1. Door thickness. Measure the sliding panel itself edge to edge, not the frame and not the panel plus the frame. Most locks in this roundup cover 22mm to 120mm, but the JNZCH only covers 30mm to 55mm, and the two drill-free glass options work on a completely different scale.
2. Stile width. Measure the flat vertical face of the handle stile where the lock body sits. You need at least 45mm on the mortise locks and 66mm on the drill-free glass option, and the narrowest lock here claims 40mm.
3. Existing mortise. If your door already has a lock, measure the cut-out pocket and match it to a 2085 slimmer or 2885 standard mortise body. Buying the wrong one is the single most common reason these locks come back.
4. Clearances. The Dhiedas needs 10mm from the frame to the lock edge and 28mm to the cylinder centre. Measure both, and photograph your stile so you can compare it against the product photos before ordering.
Two more checks are worth a minute. Confirm which way the panel opens, because not every reversible handle works on every configuration. And note whether your slider is Andersen-branded or generic, which decides whether the Yale pick applies at all.
Which lock fits which door: frame material, stile width and thickness
Door type is the first filter, and it removes most options instantly. Glass sliders, aluminum patio doors, wooden sliders and frameless swing doors each have a short list.
Andersen-branded sliding patio door: the Yale Assure Keypad is the engineered match. Everything else on this list is generic-frame hardware.
Generic aluminum or glass slider, 22mm to 120mm thick, stile 45mm or wider: the Anweller 2885 and the Eseesmart are the broadest fits, and both offer 2085 and 2885 mortise bodies. The Dhiedas covers the same thickness band with the slim 2085 body.
Slim slider between 30mm and 55mm: the JNZCH, with its trimmable spindle, is built for thin frames.
Tight stile, 40mm or narrower: the eLinkSmart claims the narrowest body at 36mm, though buyer reports on compatibility are mixed.
Frameless swinging glass door, 10mm to 12mm thick: the Perfiware LG2315, drill-free, for double doors with a 4mm to 15mm gap.
Frameless glass of 100mm to 120mm with a 66mm frame: the NGTeco, drill-free, also suitable for gates, cabinets and greenhouses.
Storm doors and multi-point lift-to-lock hardware deserve a separate word. Standard consumer smart locks in this roundup do not drive the multi-point hardware found on many sliding patio doors, so if your panel pulls down into three lock points when you slide it, no pick here will automate that. Confirm what your existing hardware does before you buy.
Are smart locks compatible with all doors? No. Compatibility is set by thickness, stile width, frame material and whether drilling is permitted, and it is the reason so many first-time buyers end up returning a lock.
Unlock methods, connectivity and power: what you can actually do
Unlock methods. Fingerprint, passcode, RFID or IC card, app and mechanical key are the five paths on most of these locks. Peek-proof PINs, where random digits can be added before or after your real code, appear on the JNZCH and both drill-free glass locks. A physical key is included on all eight, except the Yale, which is deliberately key-free.
Connectivity. Bluetooth alone covers the Eseesmart and the Yale’s Bluetooth side, which means app control at close range. Wi-Fi over a mobile app covers the JNZCH on a 2.4 GHz band, the Anweller and the Perfiware. The eLinkSmart is the only one with the gateway built in, so it needs no hub. None of these eight is Z-Wave, which matters if your home already runs SmartThings or Home Assistant, because all of them sit in their own app rather than your existing hub.
Power and weather. Battery claims run from six months on AA cells to twelve months on AAA. Most accept a power bank for emergency entry, though the Dhiedas USB port supplies temporary power only. For weather, the Eseesmart and the JNZCH both carry IP65 ratings with stated low-temperature limits, while the remaining mortise options make no published IP claim.
Security reality check. A smart lock adds keyless access, temporary guest codes and access logs. It does not stop someone breaking the glass, prying the frame, or lifting the panel if the hook does not engage properly. On a ground-floor slider, a hook bolt and a door bar still add physical resistance that no keypad provides. Pair a smart lock with solid frame hardware rather than treating it as the only defence.
Frequently Asked Questions
Can you put smart locks on sliding doors?
Yes, but only with a lock designed for sliding doors. A standard deadbolt will not fit the narrow stile of a sliding panel. What you need is a slim mortise or surface-mount body with a double hook that grips both the sliding panel and the fixed jamb, so the panel cannot be lifted off its rollers. Most of these locks fit 22mm to 120mm of door thickness on stiles at least 45mm wide.
Which smart lock is best for sliding doors?
For a generic aluminum or glass slider, the Anweller 2885 and the Eseesmart cover the widest thickness range at 22mm to 120mm and both offer slim and standard mortise bodies. The Eseesmart holds the highest average rating at 4.0 with an IP65 weather rating. If your door is Andersen-branded, the Yale Assure Keypad is the purpose-built match for that frame.
How do I measure my sliding door for a smart lock?
Measure four numbers. First, the panel thickness edge to edge, not including the frame. Second, the flat width of the handle stile where the lock body sits. Third, the existing mortise pocket, so you can match a slim or standard mortise body. Fourth, the clearances from the frame to the lock edge and to the cylinder centre. Photograph the stile so you can compare it with the product photos before ordering.
How do I install a smart lock without drilling?
Use a drill-free clamp-style mount designed for frameless glass. Two options on this list work that way and take about ten minutes without cutting into the glass. Note the limits: one fits 10mm to 12mm glass on push-pull or double-acting swing doors, the other fits 100mm to 120mm frameless glass with a 66mm frame. Neither is a sliding-track lock, and neither is a substitute for a mortise lock on a real slider.
Why are smart locks a bad idea?
The common complaints are practical rather than security. Batteries die and the lock becomes a locked door with no way in until you find the backup contact or key. App-based remote unlock depends on a vendor cloud and your router, so an outage removes a feature you paid for. Fingerprint readers fail on wet or cold fingers. And a smart lock does not stop glass breaking or frame prying, so it still needs solid hardware behind it.
Conclusion
The best smart locks for sliding doors all share one principle: the lock must physically bridge the sliding panel and the fixed jamb, because a panel on rollers is otherwise the easiest entry point on most homes. Choose on fit first and features second.
If your door is Andersen-branded, the Yale Assure Keypad is our pick, with the widest support and the longest mechanical warranty. On a generic aluminum or glass slider between 22mm and 120mm, the Eseesmart gives the strongest owner satisfaction and the Anweller 2885 gives the most body options. For a rental where you hand out codes, the Dhiedas removes the hub dependency entirely. And where drilling is not allowed, the two drill-free glass locks solve a different door type, so read their fit notes carefully first.
Measure before you order. Four numbers and a photograph will save you the return shipping that most failed installs in this category end with.
