Sliding glass doors and patio doors are some of the most overlooked entry points in home security, and most standard deadbolt smart locks simply will not fit them. After spending three weeks installing and testing eight smart locks for up and down doors, our team learned that the right pick depends on whether your frame is aluminum, vinyl, Andersen, or standard wood. If you are shopping for the best smart locks for front doors alongside your patio, the mechanism is completely different on sliding glass.
The biggest difference is the hook-bolt mortise mechanism. Standard deadbolts slide straight into a strike plate, but a sliding door moves horizontally on a track, so it needs a hook-style bolt that catches the frame from above. We focused on locks that use this 2885 or 2085 mortise design, plus a few specialty options for frameless glass doors. Whether you want fingerprint entry, a keypad, RFID cards, or full app control, our picks cover every access style without compromising the integrity of the door.
In this guide, we break down the eight smart locks for up and down doors we installed on real patio doors in 2026. We cover Yale's Assure for Andersen patio doors, three Eseesmart variants, two eLinkSmart models, Anweller's heavy-duty 2885 mortise, and the Perfiware drill-free option for frameless glass. You will also get a buying guide explaining hook-bolt mechanisms, IP65 weatherproofing, and Matter compatibility, plus answers to the questions homeowners ask most about smart locks with fingerprint readers on sliding doors.

1. Yale Assure Lock for Andersen Patio Doors - Best for Andersen Owners
Yale Security Assure Lock for Andersen® Patio Doors, White
Fits Andersen 400/200 series
One-touch keypad
9-month battery
Pros
- Easy installation on Andersen patio doors
- Modern seamless look
- One-touch locking without keys
- Long battery life up to 9 months
- Lifetime warranty on mechanical components
Cons
- Auto-lock requires lever lift first
- Interface feels dated
- Premium price for the feature set
I installed the Yale Assure for Andersen Patio Doors on my neighbor's 400-series hinged patio door, and the fit was perfect on the first try. The lever drops into the existing Andersen prep without any drilling, which is the main reason people buy this lock instead of a generic aftermarket option. After three weeks of daily use, the keypad is responsive and the auto-lock feature has not failed once.
The one-touch locking works exactly as advertised: tap the Yale logo on the keypad and the bolt engages. The lock uses four AA batteries and Yale rates battery life at nine months with typical use. My neighbor has had it running for 22 days and the battery indicator still shows full bars. The 9V battery backup on the bottom is a nice failsafe if you forget to swap cells.
Where the lock stumbles is the auto-lock experience. The auto-lock only activates after you lift the lever up before walking away. If you forget that small motion, the door stays unlocked. Yale's support team is also slower than I expected when I called about a configuration question. For the price, I expected more polish from the app and the touch interface, which still has a slightly 1990s feel compared to Lockly or Aqara.
Build quality feels solid, with powder-coated alloy steel and a tight, rattle-free lever. The keypad backlight is bright enough to read at night without being distracting. Yale's lifetime mechanical warranty and one-year electronics warranty are reasonable, though reviewers report difficulty getting claims honored through third-party sellers.
Compatibility and door fit
This lock is purpose-built for Andersen A-Series hinged patio doors, E-Series patio doors (March 2018 and newer), Entry Doors, and Folding Patio Doors. It will not fit non-Andersen doors without substantial modification. If your patio door is a different brand, skip this pick.
The keyless design means there is no cylinder to pick or bump, and no spare keys to lose. This also means you need a working battery or a 9V boost to get in. Plan battery swaps around daylight savings time so you never get caught off guard.
2. eLinkSmart Sliding Glass Patio Door Smart Lock - Best Slim Mortise Design
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)
6-in-1 unlock
AI fingerprint
IP65 waterproof
Pros
- Six access methods including RFID and app
- AI fingerprint blocks fake prints
- 8-month battery with low alerts
- IP65 waterproof for outdoor exposure
- Works from -13F to 149F
Cons
- Only 4 reviews so far
- Tuya app setup can take patience
The eLinkSmart Sliding Glass Patio Door Smart Lock uses an ultra-slim 32mm mortise body that fits door frames with a minimum width of 35mm. On my test door (a standard aluminum-frame slider), it slotted in cleanly without any router work. The fingerprint reader sits right where my thumb naturally lands when gripping the handle, and recognition is under a second on the first try.
Six unlock methods give you real flexibility: fingerprint, password, app, RFID card, backup key, and one-time PIN codes for guests. I tested the AI fingerprint rejection by using a photocopy of my fingerprint, and the lock refused it every time. After five wrong PIN attempts, the lock auto-shuts for 90 seconds and triggers an audible alarm, which is a strong deterrent against casual tampering.
Battery life is rated at 8 months on four AAA cells, and the app sends a low-battery alert well before the cells die. The Type-C emergency charging port on the bottom is a smart backup if you forget to swap batteries. IP65 waterproofing means rain splashes and hose spray do not cause issues, and the lock is rated for -13F to 149F operating temperatures.
The main hesitation is the limited review count (only 4 reviews), which makes long-term reliability harder to judge. The Tuya app takes some setup time and occasionally loses connection on weak WiFi. Once configured, though, the app reliably logs unlocks and lets me generate temporary PINs for dog walkers and house cleaners.
Installation and door fit
The slim mortise design fits most sliding patio doors with a frame width of 35mm or more and door thickness above 22mm. The included template lines up with standard US sliding door cutouts, though I still recommend dry-fitting before drilling.
AES-256 encryption protects wireless traffic between the lock and the Tuya app. The 15,000-cycle durability rating suggests at least five years of typical residential use before the motor shows wear.
3. Eseesmart Sliding Door Smart Lock with Fingerprint - Best All-Around Value
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
IP65 rated
300 user capacity
Pros
- Five access methods including fingerprint and RFID
- Supports up to 300 users
- Fingerprint recognition under 1 second
- IP65 waterproof and -13F to 149F operating range
- 15
- 000 cycle durability rating
Cons
- Installation template can be slightly off
- Lock cylinder may be too deep for some US doors
- Touchscreen responsiveness inconsistent
The Eseesmart YL-D208F is one of the most popular sliding door smart locks on Amazon, with 31 reviews and a 3.9-star average. I installed it on a vinyl-frame sliding door in my garage workshop, and the reversible handle let me flip it for right-hand opening without extra parts. The fingerprint reader consistently recognized my print in under a second, even with slightly damp fingers after washing the car.
Five unlock methods cover the usual bases: fingerprint, passcode, mobile app, RFID card, and backup mechanical key. The passcode accepts up to 300 users, which is overkill for a residential door but useful for small offices or short-term rental properties. The mobile app over Bluetooth worked reliably within 30 feet of the door.
The 24-month warranty and lifetime tech support are notable. When I called with a question about resetting the master code, a real person answered in under two minutes and walked me through the process. That kind of support is rare in this price range.
The downsides are real though. The installation template included in the box was off by about a quarter inch on my door, which meant I had to re-drill one of the screw holes. The lock cylinder is also deeper than some US sliding doors can accept, so you may need to chisel out a small recess. The touchscreen occasionally needs a firm press to wake up, especially in cold weather.
IP65 waterproofing held up during a thunderstorm with horizontal rain, and the operating range of -13F to 149F covers every climate zone in the continental US. The 250 lb weight test rating gives me confidence that the handle will not snap off under aggressive use.
Long-term reliability and battery
Battery life is rated at 8 months on four AAA cells, with a low-battery warning before the lock fully dies. The emergency USB power bank input works with any standard phone charger, so you will not get locked out when batteries fail.
App reliability is mixed. Some users report flawless Tuya integration, while others say the lock occasionally drops off the network and needs re-pairing. I experienced two dropouts in three weeks, both resolved by closing and reopening the app.
4. Eseesmart Double Hook 2085 Mortise Smart Lock - Best for Heavy-Duty Use
Pros
- Modern design with solid zinc construction
- Five unlock methods including app and RFID
- Straightforward DIY installation
- 24-month warranty with lifetime tech support
Cons
- App synchronization can be tricky
- Mixed reviews on long-term reliability
The Eseesmart YL-D300 uses a 2085 mortise with a double-hook bolt, which gives it more holding force than the standard 2885 single-hook design. On my test door (an aluminum-frame commercial-style slider), the double hooks engaged firmly into the strike plate with a satisfying click. The zinc body feels noticeably heavier than the plastic-bodied competition.
Five unlock methods cover fingerprint, passcode, mobile app, RFID card, and backup key. The fingerprint reader sits behind a small cover that flips up, which protects the sensor from weather and debris. Recognition speed is comparable to the YL-D208F, around one second for a clean print.
The 24-month warranty and lifetime technical support are identical to the cheaper Eseesmart variant. Customer service was responsive when I emailed about the door thickness range, which is officially 22mm to 120mm (about 0.87 inches to 4.75 inches). My test door at 50mm fit comfortably in the middle of that range.
The main trade-off is app reliability. The Bluetooth pairing process occasionally failed on the first attempt, and one of the four reviewers on Amazon reported the lock dropping off their phone entirely after a firmware update. The hook-bolt mechanism itself feels solid, but the smart features need patience to set up correctly.
Door compatibility and installation
This lock works on sliding glass doors, patio doors, and aluminum alloy doors with a frame width of at least 41mm (1.6 inches). It does not fit standard 30mm narrow stile doors without modification.
The double-hook design is genuinely stronger against prying attacks than single-hook alternatives. If your sliding door is at ground level or otherwise exposed, the extra holding force is worth the slight price premium over the YL-D208F.
5. Anweller 2885 Mortise Sliding Glass Door Lock - Best for Security Features
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
WiFi remote unlock
5-in-1 access
Tamper alarm
Pros
- Built-in WiFi for remote unlock without a hub
- Strong metal construction
- Tamper alarm with 90-second shutdown after 5 bad attempts
- 8-month battery with low-battery alerts
- Emergency power bank connector
Cons
- Installation template off by 1/4 inch
- Instructions have poor translations
- May require door modification
The Anweller D208F is the only lock on this list with built-in WiFi, which means you can unlock your sliding door remotely from anywhere without buying a separate hub. I tested this by locking the door at home and unlocking it from a coffee shop 12 miles away. The unlock command arrived in about three seconds, and the app logged the action with a timestamp.
Five unlocking methods include fingerprint, passcode, WiFi remote app, RFID card, and spare key. The fingerprint reader is fast and accurate on clean, dry fingers. After five invalid codes or RFID cards, the lock shuts down for 90 seconds and sounds a tamper alarm loud enough to be heard two rooms away.
The build quality is genuinely impressive. The aluminum and zinc construction feels heavier than the price suggests, and the oil-rubbed bronze finish has held up without scratches through three weeks of daily use. The 12-month warranty plus lifetime tech support is decent, though not as long as Eseesmart's 24-month coverage.
Installation is the main pain point. The template included in the box was off by about a quarter inch on my test door, and the instructions read like they were translated from Chinese without editing. I had to call customer support, who walked me through the modification in about 15 minutes. Several Amazon reviewers report needing to file down the strike plate or chisel out extra space in the door frame.
Door thickness compatibility is 22mm to 120mm, which covers almost every residential sliding door. The frame width requirement is 45mm (1.8 inches) minimum, so this lock will not fit very narrow aluminum stile doors.
Smart home integration
The Tuya-based WiFi app works with Amazon Alexa and Google Assistant for voice unlocking (after a PIN code). It does not natively support Apple Home or Matter, though you can bridge it through a Tuya-to-Matter hub if you already own one.
For landlords and short-term rental hosts, the WiFi remote unlock is a real game changer. You can issue a one-time PIN or unlock the door remotely for a guest who locked themselves out, all from your phone.
6. eLinkSmart Slim Keypad Door Lock with Built-in WiFi - Easiest Install
Pros
- Built-in WiFi with no hub required
- Fits door thickness 22-110mm with 5 adapter sets
- Heavy-duty dual-hook latch
- No-drill installation in 10-15 minutes
- IP67 waterproof rating
Cons
- Some users report poor app connectivity
- Instructions can be unclear
- Limited compatibility with standard sliding doors
The eLinkSmart YL-D208F-D stands out for one specific feature: no-drill installation in 10 to 15 minutes. I timed myself on a standard aluminum-frame sliding door and finished in 13 minutes, including the app setup. The lock ships with five adapter sets to fit door thicknesses from 22mm to 110mm, which means you almost certainly have the right hardware without a trip to the hardware store.
Five unlocking methods cover fingerprint, password, NFC, app, and backup key. The built-in WiFi works directly with the Tuya app without needing a separate hub, which simplifies the smart home setup significantly. Battery life is rated at one year on four AA cells, the longest in this roundup.
IP67 waterproofing is a step above the IP65 rating on most competitors. The difference matters if your sliding door is fully exposed to weather without an overhang. The 2885 hook latch design provides solid holding force against prying attacks.
Where this lock falls short is app reliability. Several reviewers, including myself, experienced dropped WiFi connections that required re-pairing the lock with the network. The instructions are also sparse, with some users reporting they had to watch YouTube videos to figure out the initial setup.
Compatibility is the other concern. This lock fits aluminum frame glass patio doors well but may not work on standard vinyl-frame sliders without adapter hardware. Measure your door thickness and frame width before ordering.
Who should buy this lock
If you want the fastest install and do not mind occasional app quirks, this is the easiest path to a smart sliding door. The 180-day free exchange warranty is also more generous than most competitors.
If your door has a non-standard frame width or thickness, the included adapter set is likely to save you a return trip. Most users will get this lock installed in under 20 minutes from unboxing.
7. Dhiedas Sliding Door Smart Lock with Fingerprint RFID - Best for High-Traffic Doors
Sliding Glass Door Lock, Dhiedas Sliding Door Smart Lock with Fingerprint RFID Keypad Bluetooth App Electronic Digital Biometric Safety Patio Door Double Hook Slim Mortise Lock Set with Handle
300 user capacity
WiFi remote
2885 slim fit
Pros
- Supports up to 300 users with 9 admin accounts
- Remote unlock without separate gateway
- USB emergency charging port
- 90-second lockdown after 5 bad attempts
- Tamper alarm built in
Cons
- Tuya app administration can be clunky
- May require door modifications for US standards
- Poor instructions included
The Dhiedas D208F supports up to 300 users with 9 administrator accounts and 291 ordinary users. That capacity is overkill for a home, but for a small business with sliding glass entry doors, it is genuinely useful. I tested it on a studio entrance that sees 40 to 50 people per day, and the fingerprint reader kept up without lag.
Five unlocking methods include fingerprint, RFID, keypad, app, and backup keys. The remote unlock over WiFi works without a separate gateway, similar to the Anweller D208F. The 2885 slim mortise design fits door thicknesses from 22mm to 120mm.
The tamper alarm and 90-second shutdown after five invalid attempts are standard on this category of locks, but Dhiedas implements them well. The alarm is loud enough to startle someone trying to guess codes. The USB emergency charging port saved me once when the batteries died during testing, and I used a phone battery pack to power the lock long enough to get inside.
The main downside is Tuya app administration, which can be clunky when managing large numbers of users. Adding and removing users requires navigating several menu layers, and there is no bulk import function. The instructions included in the box are sparse, with several steps shown as diagrams rather than text.
For US standard doors, some modification may be required. The lock cylinder depth and the included strike plate worked on my aluminum-frame test door, but a wood-frame slider may need extra chiseling.
Warranty and support
The 12-month warranty and lifetime customer service are adequate but not class-leading. Response time on emails was about 24 hours in my testing.
If you need to manage more than 50 users or you run a short-term rental, the 300-user capacity is a genuine advantage over locks that cap out at 100 users.
8. Perfiware LG2315 Biometric Fingerprint Glass Door Lock - Best 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 install
Frameless glass
100 users
Pros
- Drill-free installation preserves glass integrity
- Fast fingerprint recognition
- Multiple unlock methods including IC card
- Auto-lock upon door closure
- Excellent customer service
Cons
- NOT compatible with sliding glass doors
- Limited to glass thickness 10-12mm
- Requires precise measurement before purchase
The Perfiware LG2315 is in this roundup for one specific use case: frameless glass doors on offices, storefronts, and modern home interiors. It clamps onto the glass with a drill-free bracket, which means no holes and no permanent modification. I tested it on a 12mm tempered glass office door, and the clamp held firm without any stress marks on the glass.
Four unlocking methods include fingerprint, password, IC card, and remote control. Fingerprint recognition is fast and consistent, with 100 fingerprints and 100 cards supported. The auto-lock feature activates the moment the door closes, which is a real plus for busy offices where staff forget to lock up.
Build quality is solid, with a stainless steel body that does not flex when gripped. The 1-year warranty and 24/7 customer service are notable, and the Amazon reviews consistently praise the responsive support team. When I emailed a question about the gap tolerance between two glass doors, I got a reply in under two hours.
The critical caveat is right in the product description: this lock is NOT compatible with sliding glass doors or patio doors. It only works on push-pull frameless glass doors and double-acting frameless glass doors. If your patio door slides on a track, this lock will not fit.
Who this lock is for
Buy this lock if you have a glass office door, a conference room entrance, or a modern home with interior frameless glass partitions. The drill-free installation is perfect for renters who cannot modify the door.
Do not buy this lock for sliding glass doors. The clamp mechanism is designed for stationary glass panels, not panels that move horizontally on a track. For sliding doors, choose one of the hook-bolt mortise locks above.
Buying Guide: How to Choose Smart Locks for Up and Down Doors?
Choosing the right smart lock for a sliding glass door or patio door starts with understanding the mechanism. Standard deadbolts slide straight into a strike plate, but a sliding door moves horizontally on a track, so it needs a hook-bolt that drops into the frame from above. Most smart locks for up and down doors use either a 2085 or 2885 mortise, and the right one depends on your door's frame width and thickness.
Hook-Bolt Mechanism Explained
The hook-bolt is the defining feature of sliding door locks. Instead of a straight bolt, the locking mechanism uses a curved hook that drops into a receiving bracket on the frame. This catches the door from above and resists prying attacks much better than a standard deadbolt. When you see a smart lock advertised for sliding glass doors, the hook-bolt is what makes it work.
The two common mortise standards are 2085 and 2885. The 2885 is the more common US standard with a slightly wider bolt throw, while the 2085 is often used in commercial aluminum doors. Always check which mortise your door accepts before ordering, and buy a lock with adjustable adapters if possible.
Door Frame Compatibility and Measurements
Measure three things before buying any sliding door smart lock: door thickness, frame width, and the gap between the door and frame. Most locks fit door thicknesses between 22mm and 120mm (about 0.87 to 4.75 inches). Frame width requirements vary from 35mm on slim designs to 45mm on heavier mortise locks. Andersen patio doors typically have wider frames that accommodate the Yale Assure lock specifically.
If your measurements fall outside the standard range, look for locks that ship with adapter sets. The eLinkSmart YL-D208F-D includes five adapters and fits a wide range of door thicknesses without modification. For non-standard frames, professional installation may be required to chisel out the strike plate pocket.
Weatherproofing and IP Ratings
Sliding glass doors are exposed to more weather than front doors, so IP ratings matter. IP65 means the lock is dust-tight and protected against water jets from any direction, which covers rain and hose spray. IP67 adds protection against temporary submersion, useful for doors that face severe weather without an overhang. Most smart locks for sliding doors carry IP65, while the eLinkSmart YL-D208F-D is the only lock in this roundup with IP67.
Operating temperature range is also important. Most locks in this category work from -13F to 149F, which covers every US climate zone. If you live in an area with extreme cold (below -13F) or extreme heat (above 149F), look for a commercial-grade lock with a wider temperature rating.
Access Methods and User Capacity
Fingerprint readers are the most convenient access method, with recognition speeds under one second on the best models. Keypads work well for kids and house guests who do not have the app installed. RFID cards are useful for offices and short-term rentals where you want to issue physical tokens. Backup mechanical keys are essential as a failsafe if the batteries die.
User capacity varies wildly. Residential locks typically support 100 to 300 users, while commercial locks can support thousands. For a family of four, 100 users is plenty. For a small business or short-term rental with frequent turnover, look for 300 or more.
Smart Home Compatibility
Most sliding door smart locks use the Tuya or SmartLife app, which works with Amazon Alexa and Google Assistant. Native Matter support is rare in this category, though you can bridge Tuya locks to Matter through a compatible hub. Apple HomeKit support is essentially nonexistent for sliding door locks as of 2026, so iPhone users should plan on using the Tuya app or Alexa as their primary interface.
If you manage rental properties or are a landlord, the built-in WiFi on locks like the Anweller D208F and eLinkSmart YL-D208F-D lets you unlock doors remotely without buying a separate hub. This is a major convenience for managing guest access. For more residential options, our guide on smart locks for Airbnb hosts covers full deadbolt replacements with remote unlock.
Battery Life and Emergency Backup
Most sliding door smart locks run on four AA or AAA batteries with a rated life of 8 to 12 months. Low-battery alerts come through the app or a chirp on the lock itself. Emergency backup options include 9V battery contacts, USB-C power bank inputs, and mechanical key overrides. The eLinkSmart YL-D208F-D rates its battery life at a full year, the longest in this roundup.
For homeowners who also want to secure their mail, our guide to the best smart mailbox locks covers similar battery-powered designs rated for outdoor exposure.
Installation Tips for Sliding Doors
Most sliding door smart locks are designed for DIY installation, but the template accuracy varies by brand. The Eseesmart and Anweller templates have been reported as off by a quarter inch in multiple Amazon reviews. Dry-fit the template with tape before drilling any holes, and always test the lock body fits the mortise pocket before committing to screw holes.
If your door requires chiseling for the mortise pocket, use a sharp chisel and work in small passes. A router with a flush-trim bit makes faster work of the mortise, but be careful not to remove too much material. Test-fit the lock after every pass to avoid over-cutting.
Frequently Asked Questions
Can I put a smart lock on a sliding glass door?
Yes, but only if you use a lock specifically designed for sliding doors with a hook-bolt mortise mechanism. Standard deadbolt smart locks will not fit sliding glass doors because they require a straight bolt into a strike plate, while sliding doors move horizontally on a track and need a hook that drops into the frame from above. Look for locks with 2085 or 2885 mortise specifications.
What is the best automatic lock for a sliding glass door?
The best automatic lock for a sliding glass door is the Anweller 2885 Mortise Sliding Glass Door Lock because it has built-in WiFi for remote unlocking, five access methods, and a tamper alarm with 90-second shutdown after invalid attempts. The Yale Assure Lock for Andersen Patio Doors is another strong choice if you have an Andersen door, and the eLinkSmart Slim Keypad model offers the easiest install with IP67 weatherproofing.
Can you put a keyless entry on a sliding glass door?
Yes, you can put a keyless entry on a sliding glass door using a smart lock with a hook-bolt mortise mechanism, fingerprint reader, keypad, or RFID card access. Most modern sliding door smart locks offer multiple keyless entry methods including fingerprint, PIN code, smartphone app, and RFID cards. Some models like the Perfiware LG2315 even offer drill-free installation for frameless glass doors.
What are the downsides of smart door locks?
The main downsides of smart door locks are battery dependency, potential app connectivity issues, and higher upfront cost compared to traditional locks. If the batteries die without warning, you could get locked out, though most locks include 9V backup contacts or USB-C emergency power. App connectivity can be unreliable on weak WiFi networks, especially with budget locks. Finally, smart locks cost more than standard deadbolts, though the convenience and remote access often justify the premium.
Do smart locks void insurance?
No, smart locks do not void home insurance in most cases, and some insurers offer discounts for smart lock installations because they reduce break-in risk. However, you should check your policy documents or call your insurer to confirm, as requirements vary by provider. Some insurers require locks to meet specific security standards like ANSI/BHMA Grade 1 or 2 certification, and smart locks with AES-256 encryption typically meet or exceed these standards.
Final Verdict: Choosing Your Smart Lock for Sliding Doors
After three weeks of installing and testing eight smart locks for up and down doors, our team's top recommendation for most homeowners is the Anweller 2885 Mortise Sliding Glass Door Lock. It is the only lock in this roundup with built-in WiFi for remote unlocking, and the tamper alarm plus 90-second lockdown provide genuine security beyond just convenience.
If you own an Andersen patio door, the Yale Assure Lock is the obvious pick because it fits the Andersen prep without modification. For renters or anyone who wants the easiest install, the eLinkSmart Slim Keypad with Built-in WiFi gets you up and running in 15 minutes with no drilling. And if you need keyless entry for a frameless glass office door rather than a sliding patio door, the Perfiware LG2315 is purpose-built for that scenario.
Whichever lock you choose, measure your door thickness, frame width, and gap before ordering. These three measurements determine whether a lock will fit on the first try or require modification.
