A double door is where smart lock shopping most often goes wrong. The bolts are deeper than a standard front-door deadbolt, the handles project further toward the frame, and half the time there is already a multipoint bar running from the bottom rail into the frame. Buy the wrong body and the door will not close, or it will close over an inactive leaf nobody secured.
We spent weeks reading spec sheets, install guides and owner threads on the best smart locks for double doors, because the question buyers actually ask is not which lock has the longest feature list. It is which one physically fits the leaf you open, still takes a real key, and can share codes with the rest of the household. One r/HomeKit owner described an August lock on an outer security door as “too bulky and wide for me to be able to close it without hitting the door jamb.” Lock depth is the number buyers report being unable to find anywhere, so door dimensions appear in every review below.
This roundup covers eight locks that genuinely suit double-door setups, plus the hardware questions that decide whether a smart lock belongs on your door at all. For the wider picture on keyless entry, our general smart lock roundup covers single-door basics, and biometric door lock reviews goes deeper on fingerprint readers.

1. Veise KS01B Keypad Lock with 2 Lever Handles – Best Overall for Double Doors
Veise KS01B Keypad Door Lock with 2 Lever Handles Set, Oil Rubbed Bronze
Keypad deadbolt plus two lever handles
Ansi Grade 3 and BHMA tested
IP54 rated
Fits 1-3/8 to 2 inch doors
Pros
- Deadbolt and both matching levers packed in one box
- 20 permanent codes plus one-time guest PINs
- Anti-peeping dummy password and lockout after 10 failed tries
- Vacation mode and silent mode
- BHMA tested with IP54 dust and water resistance
Cons
- Batteries not included
- No app or Wi-Fi so codes are managed at the keypad only
- Keep liquids away from the keyhole
A mismatched double door is easy to end up with: a deadbolt on the active leaf, an old knob left on the inactive leaf, and two halves of the entrance that no longer match. The Veise KS01B avoids that, because the keypad deadbolt and both lever handles are packed together.
With 2127 ratings averaging 4.6 stars and 79% five-star, this is the deepest review base in the group. That matters here, because a double door is a high-cycle door: two people passing through several times a day, a door coordinator pulling both leaves together, and an interior thumb turn that gets grabbed every time.
On the security side, the manufacturer lists ANSI Grade 3 and BHMA testing, IP54 water and dust resistance, and 200000+ cycle testing. Grade 3 is an honest expectation for a residential double door rather than a headline to oversell, and the IP54 rating is what you want if the active leaf sits under a porch without climate control.
Programming is done entirely at the keypad, with no app, no Wi-Fi and no account to set up, and the lock keeps working through a network outage. Twenty permanent codes plus one-time guest PINs cover a family and a house sitter, and the one-touch lock works by holding any keypad key for two seconds.
What to check before you order
Measure your door thickness first. The KS01B fits 1-3/8 inch to 2 inch doors, which covers most residential French and double entry doors but not a thick insulated steel unit. Confirm your existing latch measurement before drilling anything.
Because there is no app, this is a single-leaf lock with no remote sharing. If you want to issue a code from your phone while you are at work, the Philips WiFi model below is the better fit.
Where it falls short
Batteries are not included, and four AA cells are the only power source, so budget for that before the first weekend. The manufacturer also advises keeping liquid and prolonged direct sunlight away from the keyhole and interior, which matters on an exposed south-facing entry.
There is no Bluetooth or Wi-Fi radio at all. That is a feature on a door where the network is unreliable, and a limitation on a door where you want remote unlock. Decide which side of that line your household sits on before you buy.
2. Philips WiFi Keypad Lock with Handle – Best for App Control and Two-Door Homes
Philips WiFi Keypad Door Lock with Handle, Built-in WiFi, APP Remote Control, Voice & Fingerprint Unlock, Smart Locks for Front Door with Auto Lock, Keyless Entry Deadbolt, Satin Nickel
Built-in 2.4GHz Wi-Fi, no hub
App remote unlock and history
Alexa and Google Assistant
Fits 1-3/8 to 1-3/4 inch doors
Pros
- No hub or bridge to buy or power
- Remote lock and unlock with real-time access history
- Permanent one-time and recurring PIN codes
- Auto-lock adjustable 0 to 180 seconds
- Matching handle set in the box
Cons
- Eight AA batteries not included
- Wi-Fi limited to 2.4GHz networks
- Five-second reset-button activation before first use
A double-door home is where hub-free Wi-Fi earns its place. A bridge sitting on a shelf next to your router is one more thing to power, update and eventually fail, and the Philips DDL242X-1HW connects straight to a 2.4GHz network instead. It ranks in the top thousand in Tools and Home Improvement, with 819 ratings at 4.3 stars and 75% five-star.
Unlock methods cover what most double-door households need day to day: fingerprint, PIN, app and voice control. The app handles permanent, one-time, periodic and recurring codes, so a house sitter gets a PIN that stops working on a date you set rather than a code you remember to delete.
The interior body is the part to watch on a double door. The unit is rated for doors 1-3/8 inch to 1-3/4 inch thick, which is narrower than some insulated exterior units, and the included levers mean you are not trying to match an old handle to a new deadbolt. Auto-lock timing is adjustable from 0 to 180 seconds through the app, which is how you stop the leaf from re-locking while you carry groceries through both doors.
Owners running two locks on a double door should know that codes are managed per lock inside the same app, so the two leaves sit side by side on one screen. That is what makes a two-leaf setup practical rather than a second chore.
What to check before you order
The thickness range stops at 1-3/4 inch. If your double door is a thicker modern unit, this is the wrong box. Measure before you order, because the return process for a drilled-and-fitted lock is a lot more work than a tape measure.
Also confirm your router is set to 2.4GHz. That is the only band this lock connects to, and it is a five-minute fix in most router settings rather than a deal-breaker.
Where it falls short
Eight AA alkaline batteries are required and not included, a heavier power draw than the four-AA units described in this roundup. Owners also report a five-second reset-button hold before the lock will activate the first time, and initial network pairing is where most setup calls go wrong.
If your Wi-Fi drops, remote unlock stops working until it comes back. Keypad and fingerprint entry both continue, so this is an inconvenience rather than a lockout.
3. HIDALIFE Keypad Deadbolt 2 Pack – Best for Locking Both Leaves at Once
Keypad Keyless Entry Door Lock with Handle Smart Digital Deadbolts 2 Pack
Two complete keypad lever locks
Adjustable 2-3/8 inch backset
Privacy PIN function
Zinc alloy, 250000 cycles
Pros
- Covers both leaves in a single purchase
- Reversible for either hand without tools
- Privacy PIN adds random digits around your real code
- 2000N pressure resistance and 250000 cycle rating
- Automatic 5-second locking plus passage mode
Cons
- Batteries not included
- Touchscreen sometimes needs several taps to wake
- Multi-packs can arrive keyed differently
- No app or Wi-Fi
- Install documentation is thin
Most two-leaf advice says buy two locks, and this package is two locks. With 1049 ratings at 4.1 stars, it is one of the largest review samples in the roundup, which makes the durability figures more useful than a marketing sheet: 2000N pressure resistance, 240-hour salt spray and a 250000 cycle rating on zinc alloy bodies.
The privacy PIN function is the feature most worth knowing about on a double door. You enter your real code with random digits added before or after it, so someone standing behind you at the inactive leaf sees a string of numbers that does nothing. On a pair of doors with a wide sightline, that matters.
The backset is adjustable between 2-3/8 inch and 2-3/4 inch, and the handle reverses for either handed door without a conversion step. Each pack includes two exterior keypads, two interior assemblies, an adjustable latch, strike plate, two levers, two backup keys and a drilling template.
What to check before you order
Check whether your two locks arrive keyed alike. Owners report that multi-packs can arrive keyed differently, which means each leaf needs its own spare key and your household carries two keys instead of one. That is a minor annoyance, but it is avoidable if you know to ask.
Because there is no app, code changes happen at the keypad. On a double door you will be walking to the exterior side of the active leaf every time, so plan where the spare key lives before you hand out a PIN.
Where it falls short
The touchscreen keypad sometimes needs several taps before the numbers illuminate, and there is no physical button to wear out but there is a sensor to fail. A small number of owners also report a mechanism that stopped engaging, which left them using the physical key only.
Documentation is the weakest part. Instructions and install videos are described as not very helpful, so budget extra time for the drilling template step and check your hole spacing against the adjustable latch before you start.
4. Ulecoce Fingerprint Keypad Deadbolt with Knob Set – Best for Fingerprint Entry
Ulecoce U68 Fingerprint Keypad Deadbolt with Knob Set, Matte Black
Fingerprint in as little as 0.3 seconds
Up to 512 stored entries
App control and access logs
IP54 rated, 3-year warranty
Pros
- Five unlock methods including fingerprint and key
- Up to 512 stored fingerprints and passcodes
- App control with real-time door-open alerts
- Auto-lock adjustable 5 to 60 seconds
- Three-year warranty with 24/7 email support
Cons
- Code changes require being within Bluetooth range
- Voice and true remote unlock need a separate gateway
- No written instructions in the box
- Awkward joint to press together during install
On a double door the fingerprint reader earns its place more than it does on a single front door, because the active leaf is the one you touch while juggling the other. The manufacturer claims recognition in as little as 0.3 seconds with a self-learning algorithm, and 933 ratings at 4.3 stars put that claim in reasonable context. Treat 0.3 seconds as a manufacturer figure, not a measured result.
Capacity is the real story here. Up to 512 stored fingerprints and passcodes, with one-time, permanent, scheduled and recurring code types, is roomy for a family plus cleaners, sitters and short-term rental guests without recycling codes. The app keeps access logs and sends real-time door-open alerts.
Construction is zinc with IP54 water and dust resistance, anti-drill and heat resistance claims, and a 3-year warranty with lifetime after-sales support. The handle set includes two knobs, so the active leaf gets a matching pair rather than a deadbolt fighting an old lever.
Installation is screwdriver-only and reversible for either handing, which keeps the double-door conversion to a single afternoon on most standard doors.
What to check before you order
Creating or modifying access codes requires you to be within Bluetooth range of the lock. If you manage a rental property across town, that limitation is the deciding factor and no amount of app polish changes it. Several owners do run several locks across rental doors, so it works when you are on site.
Alexa and Google Assistant work only when the lock is paired with a Ulecoce gateway sold separately. Treat voice control as an add-on cost, not a box feature.
Where it falls short
It comes without written instructions, so the install video and online photos are your reference. The joint connection point during installation is also described as awkward to press together, which is a five-minute annoyance rather than a blocker.
Because the fingerprint reader is the headline, cold or wet hands at the exterior keypad will slow it down. Five physical keys are included, and the key cylinder is the fallback you will actually reach for in winter.
5. Philips Keypad Lock Set with 2 Lever Handles – Best for Fully Offline Use
Philips Keypad Front Door Lock Set, Smart Deadbolt with 2 Lever Handle
Fingerprint and PIN and key unlock
Offline, no app or Wi-Fi
Fits 1-3/8 to 2 inch doors
Ansi certified
Pros
- Complete lock and handle set in one package
- Four unlock methods including one-time PIN
- No data transmission and no account needed
- Alarms for wrong entry
- low battery and jamming
- Beginner-friendly installation instructions
Cons
- Interior assembly is largely plastic with weak-feeling clips
- Some play in the interior knob when throwing the bolt
- Interior wiring cable can obstruct reassembly
- Batteries drain relatively quickly
Nothing leaves this lock. There is no app, no Wi-Fi and no data transmission, which makes it the pick for a garage-to-house door, a rental cottage or any entry where the owner does not want a network dependency. It is also among the highest rated locks here at 4.4 stars across 256 ratings.
It is a complete set: one fingerprint deadbolt with two matching lever handles, covering the lock and handle hardware in a single coordinated package. Doors 1-3/8 inch to 2 inch thick with a 1 inch edge hole and a 2-3/8 inch or 2-3/4 inch backset covers the standard residential double-door prep.
Feature-wise it is a full set: fingerprint, PIN, one-time guest PIN and physical key, with an adjustable auto-lock timer from 30 to 180 seconds. Alarms cover wrong entry attempts, low battery and jamming, the anti-peeping password function adds decoy digits around your real code, and the manufacturer lists ANSI certification for this model.
On a double door, the one-time PIN is the feature that earns its keep. Give a dog walker or a contractor a code that expires after a single use and nobody is copying down a permanent entry code from the inactive leaf.
What to check before you order
Look at the interior assembly, not the exterior. Reviewers describe the outside as solid and the inside as largely plastic, with cover clips that feel cheaper than the exterior suggests. You touch that interior hardware every single time you come in, so it is worth holding in your hand before committing.
Confirm the door thickness sits between 1-3/8 inch and 2 inch, and that your edge hole is 1 inch. Both are standard on residential doors but worth confirming against an unusual replacement unit.
Where it falls short
Some play shows up in the interior knob when turning the deadbolt, and the interior wiring cable can get in the way while you reassemble the cover. Both are tolerances rather than faults, but on a lock you use daily you will feel them.
Batteries drain relatively quickly by owner report, and one review described a lock that stopped responding in cold weather and locked the owner out until a replacement arrived. Keeping the physical key habit matters more on this model than the rest.
6. Richelock IU52 Double-Sided Keypad Door Lock – Best for Uncovered and Cold Entry Doors
Richelock IU52 Double-Sided Keypad Door Lock, All-Weather, Fully Waterproof Keyless Entry with Dual-Sided Programmable Codes, Same Key Both Sides for Outdoor, Indoor, Gate & Fence
Keypads and keys on both sides
Rated -22F to 176F
Up to 50 codes per side
Type-C emergency power
Pros
- Genuinely two-sided
- with a keypad and key on both sides
- All-weather waterproof zinc construction
- Code sync between the two keypads
- Auto-lock timer from 2 seconds to 12 hours
- Emergency Type-C power under each handle
Cons
- Batteries not included
- Two AA cells required per side
- Touch control needs finger contact to wake the backlight
Most double-door sets give you an active and an inactive side, and only the active side gets powered hardware. The Richelock IU52 inverts that by putting a backlit keypad and a mechanical key on both sides of the door, which suits gates, fences and any pair of doors where both leaves need independent entry.
Manual claims are worth flagging here. The manufacturer rates the zinc construction for -22F to 176F and calls it fully waterproof, so an uncovered porch, a screened side entrance or a northern climate is where this lock belongs. It carries 148 ratings at 4.3 stars.
Each keypad stores up to 50 unique 1-15 digit codes, and the two keypads can sync codes so you program once and both sides follow. That pairing convenience is unusual among the locks here, and it is the closest thing in this roundup to a matched set for a double door.
Auto-lock is adjustable from 2 seconds to 12 hours, with manual, guest and silent modes, and each handle has an emergency Type-C power port underneath for the day the AA cells die. It fits standard US doors with a 2-3/8 inch or 2-3/4 inch backset and installs with a Phillips screwdriver.
What to check before you order
Confirm the backset on your double door, because this is a handle-and-keypad assembly rather than a standard deadbolt, and it is designed for a door with a usable handle set on both leaves. If your inactive leaf has only a deadbolt and no handle, this layout will not drop into place.
Plan for batteries from the start. Two AA per side are needed and neither set is included in the box.
Where it falls short
This is a keypad and touch lock with no app, no fingerprint and no remote access, and everything is done at the keypads. That is a limitation in a connected home and a benefit everywhere else.
The touch control needs some finger contact to wake the backlight, so gloves and very cold hands slow entry. Reviewers flag missing batteries as the most common complaint, so treat the stated 2+ year battery life as a best case rather than a promise.
7. HISAFE Fingerprint Double Door Handle Set – Best for a Matched Keyed and Dummy Pair
HISAFE Fingerprint Double Door Handle Set with Keypad Deadbolt, Right Hand
Keyed and dummy double handleset
Touchscreen PIN and fingerprint and key
No app or Wi-Fi
Doors 1-3/8 to 2 inch thick
Pros
- Keyed and dummy layout built for two-leaf doors
- Three unlock methods including an emergency key
- Up to 20 user codes
- Two latch sizes and adjustable handle stem
- Works offline with no app
Cons
- Handedness conversion is needed on one swing direction
- Batteries not included
- Only 36 reviews so long-term data is thin
The HISAFE X-2018DB-E-SET is the closest match in the roundup to a conventional double front door build. It arrives as a double handleset with one keyed side and one dummy side, which is how most double front doors are built: one leaf opens, the other is held by matching hardware and secured by the frame.
Unlock methods are touchscreen passcode, fingerprint and an emergency key, with a manual thumb turn on the inside and up to 20 user codes. There is no app and no Wi-Fi, so it operates entirely offline, and a 4.2 star average across 36 ratings puts the owner feedback in positive territory.
What to check before you order
Handedness is the one real trap. The set is packaged for one swing direction and converted for the other by pulling and turning the tail piece before fitting, which reviewers cite as the most common complaint. Work out which leaf opens and in which direction before the box is open.
Door thickness is 1-3/8 inch to 2 inch, and the set includes latch sizes of 2-3/8 inch and 2-3/4 inch with an adjustable handle stem for hole spacing, which gives you some tolerance on an older double door.
Where it falls short
With 36 ratings, there is very little long-term reliability data on this one, and a double entry door is a high-cycle location. That thin evidence base is the main reason it sits below the Veise in our ranking despite the better-matched hardware layout.
Batteries are not included, and the fingerprint reader is a nice addition rather than the reason to buy, because 20 codes is a smaller capacity than most locks here and there is no way to add codes remotely.
8. Philips Wi-Fi Front Lock Set with 2 Handles – Best for Five Unlock Methods
Philips Wi-Fi Front Lock Set, Smart Keypad Deadbolt Lock with 2 Handles
Five unlock methods including voice
Up to 100 user codes
Batteries included
Fits 35-50mm doors
Pros
- One of the two highest rated locks here at 4.6 stars
- App remote unlock with notifications and history
- Up to 100 permanent codes plus one-time PINs
- Batteries and a two-handle set both included
- Responsive support on a unit that would not pair
Cons
- Audible lock and unlock voice announcement
- Requires pre-drilling holes to the specified dimensions
- Only 48 ratings compared with the other locks here
The Philips DDL240X-1HW-H2 shares the highest rating in the roundup at 4.6 stars, with 80% five-star, from 48 ratings. That is excellent feedback on a small sample, and the sample size is the reason it is not the top pick: 2127 ratings tell you more about how a lock behaves year after year than 48 do.
Where it leads is unlock method count. App, fingerprint, PIN, physical key and voice assistant, with up to 100 permanent user codes plus unlimited one-time PINs that expire immediately after use. The Philips app handles remote lock and unlock, real-time notifications and access history, and Alexa and Google Assistant are both listed as controllers.
Batteries are included in the box, which none of the other seven locks here can say, and the set also includes a matching two-handle set. The auto-lock timer is adjustable from 30 to 180 seconds.
Support is worth noting too. Owners report a no-hassle replacement for a unit that would not connect to Wi-Fi, which is the sort of thing that matters when a lock is the only way into your house.
What to check before you order
Pre-drilling is required to the specified dimensions rather than being a pure retrofit over an existing bore. On a finished double door that is real work with a real risk of mismeasuring, and it is the reason to slow down on this model.
Door thickness is 35-50mm, which is a narrow window. If either leaf is thicker than 2 inches, this set is not a candidate regardless of how good the rating looks.
Where it falls short
The audible lock and unlock voice announcement is the most common complaint, and it is a real annoyance on an interior-facing double door at odd hours. Some buyers also needed to pre-drill holes to spec even when following the instructions.
At 48 ratings, treat every performance figure as provisional. The five unlock methods are genuine, but the long-term record is not yet built, and the audible confirmation is something you cannot turn off in the feature list.
Do Smart Locks Work with Multipoint Locks?
Yes, but rarely by replacing one. A multipoint or three-point lock is a bar that engages the top and bottom of the frame when you lift the door to lock it, pulling both leaves together so the inactive leaf cannot be pushed open on its own.
A standard smart deadbolt only throws into one edge, so it does not replace that function. You have three realistic options.
The first is to keep the multipoint system and smart-lock only the active leaf, which is what most homeowners do and what we recommend. Your existing top and bottom hardware stays exactly as it is, and the powered lock handles daily entry.
The second is to replace the multipoint mechanism with a conventional lock set and rely on a surface-mounted or keyed pull on the inactive leaf. This gives a cleaner look but gives up the frame-level security the bar was there to provide, so it is a real trade rather than an upgrade.
The third is to buy into a door-brand ecosystem. Some French door and patio door manufacturers ship their own connected hardware designed to drive the existing frame system, and that hardware is what legitimately controls the top and bottom locks.
One caution from a recent r/HomeImprovement thread: a homeowner reported a proprietary Renewal by Anderson multipoint system that would not secure the passive door even with everything locked and engaged, describing it as a mechanical engineering error. Brand-locked hardware that nobody else can service is a risk worth weighing.
Which Leaf Needs the Smart Lock?
The active leaf, the one you open every day, gets the powered lock, while the inactive leaf stays mechanically fixed. Putting an expensive fingerprint lock on the leaf that never opens is a familiar double-door mistake.
One smart lock is enough for most homes. You get keypad or app entry, a physical key and codes you can revoke, and you avoid doubling your battery maintenance. A door coordinator or astragal already handles pulling the passive leaf into the frame.
Two situations call for two locks. If both leaves open independently, or if you want separate access from a garage and a garden entrance, then one lock per leaf is correct. The HIDALIFE two-pack covers that case in a single purchase.
For the inactive leaf, a fixed pull, a keyed knob or a surface-mounted deadbolt is usually the right hardware. Skip another electronic lock unless you have a specific reason, because every powered unit is another battery set, another firmware update and another thing to fail.
How to Pair Two Smart Locks Under One App?
Pairing works only if both locks speak the same language. The Philips WiFi models here run on the same Philips Home Access app, so two locks of the same model share one account, one code list and one activity view, and you can tell which leaf was opened and when.
The HIDALIFE two-pack and the Veise KS01B have no app at all, and they are managed at the keypad. Pairing them means matching by hand: you program the same set of codes into each lock and keep a written record. That is more work but it is also more durable, because nothing depends on a server.
The Ulecoce sits in between. It has an app for codes, logs and door-open alerts, but code changes must happen within Bluetooth range of the lock, and true remote unlock needs a gateway sold separately. Two locks in one home are manageable; two locks on two separate rental properties are not.
Whichever route you take, the rule is the same. Give the inactive leaf fewer privileges than the active one, and never issue a permanent code to anyone you would not hand a key to.
How to Measure Your Double Door Before You Buy?
Taking four measurements before you buy solves most of the fit problems buyers report on forum threads. It takes ten minutes with a tape measure instead of a return.
Door thickness, measured on the active leaf away from the hinges. Most locks in this roundup take doors from 1-3/8 inch to 2 inch, with the Philips WiFi handle lock stopping at 1-3/4 inch and the Philips Wi-Fi front lock set listing 35-50mm.
Backset, the distance from the door edge to the centre of the round bore. Most US residential doors use 2-3/8 inch or 2-3/4 inch, and the HIDALIFE and Richelock units adjust between the two. Measure yours rather than assuming, especially on a replacement door.
Stile width on the inactive leaf, measured across the face where a handle would mount. A narrow French door stile is the reason some sets do not fit, and the HISAFE adjustable handle stem is worth having for exactly this case.
Jamb clearance, the gap between the open door and the frame. This is the number behind the most common double-door complaint. Buy a lock whose interior body and handle projection clear that gap with the door fully open, especially if a screen door or storm door sits outside.
Also check the edge bore diameter, typically 1 inch, and whether your existing strike plate and latch will be reused or replaced. Bringing those numbers to the hardware aisle eliminates nearly every fit problem we hear about.
When a Smart Lock Is the Wrong Answer?
Glass sidelights and panels mean no bore to fit into. If the active leaf is mostly glass, the answer is a surface-mounted retrofit lock that clamps to the door face, and none of the eight picks here are that category.
Proprietary brand-locked multipoint hardware is the second case. If your French door came with an integrated system from the door manufacturer, a generic smart deadbolt will not control the top and bottom locks, and forcing it in can leave you with two systems and one security problem.
A third case is any door where you cannot reach the interior assembly. Wrought-iron security doors with narrow internal channels are the classic example, and that is exactly the setup where an over-thick lock body stops the door closing. If you cannot get a tape measure inside the door, this is a locksmith job, not a DIY afternoon.
Finally, skip the upgrade entirely if nobody wants codes or remote access. A solid mechanical deadbolt with a keyed knob on the passive leaf needs no batteries and cannot fail with a flat cell or a dead router.
Frequently Asked Questions
Which lock is best for a double door?
A keypad deadbolt with lever handles on the active leaf, plus a fixed pull or keyed knob on the inactive leaf, is the best answer for most double doors. Lever handles and a low-profile interior body clear a tight jamb better than a tall touchscreen lock. Our pick is the Veise KS01B, which ships the deadbolt and both handles in one box.
Do smart locks work with multipoint locks?
A standard smart deadbolt does not replace a multipoint bar, because the bar engages the top and bottom of the frame rather than one edge. You can keep the existing multipoint system and smart-lock only the active leaf, replace the bar with a conventional set and a fixed pull, or buy the door manufacturer’s own connected hardware that drives the frame system.
What is the best smart lock for French doors?
For French doors, a lever-handle keypad deadbolt with a reversible body and an adjustable backset is the safest fit, because handles project less than a long deadbolt and a reversible body handles either swing. The Veise KS01B fits doors 1-3/8 inch to 2 inch thick and includes both handles. Check stile width on the inactive leaf before ordering.
Do I need a smart lock on both leaves of a double door?
Usually not. The active leaf is the one you open daily and it gets the powered lock. The inactive leaf is held by matching fixed hardware and the frame coordinator. Two locks make sense only when both leaves open independently or you want separate access points, such as an entry door and a garden door.
What are the downsides of smart door locks?
The main downsides are battery dependence, dependence on connectivity for remote features, and the risk of being locked out if the cell dies or the fingerprint reader fails. Most locks in this roundup include a physical key, and the offline models with no app keep working through a network outage. Check low-battery alerts before you rely on any of them.
How thick does a door need to be for a smart lock?
Most residential smart locks accept 1-3/8 inch to 2 inch doors, and several models in this roundup specify that range directly. The Philips WiFi keypad lock with handle stops at 1-3/4 inch, and the Philips Wi-Fi front lock set lists 35-50mm. Measure the active leaf away from the hinges before ordering, since an insulated exterior door can exceed 2 inches.
The Best Smart Locks for Double Doors in 2026
The Veise KS01B is the best smart lock for double doors for most households, because it pairs a keypad deadbolt with two lever handles in one box, carries the deepest review base of the eight and needs no hub, app or account. Choose the Philips WiFi keypad lock with handle when you want remote codes and two leaves under one app, and choose the HIDALIFE two-pack when both leaves need to open independently.
Measure your door before anything else, keep the physical key override, and treat an existing multipoint bar as a separate decision from the smart lock. Those three steps prevent nearly every fit problem we hear about. If you want more general coverage, our biometric lock roundup compares fingerprint options in depth.
