How we chose the top Smart Deadbolt
So your door has two separate holes in it, one for your handle and one for your deadbolt? If so you are in the right place.
You have several options here based on the current smart locks on the market.
- Replace entire deadbolt with smart lock mechanism
- These locks will provide you with a new set of keys - Replace just the interior deadbolt mechanism only
- From the exterior your door will look the same
- Typically you can keep your existing lock keys - Deadbolt Attachment
- This is a rare type and only 1 lock on the market does this (Sesame which uses 3M tape to attach to your existing deadbolt).
Things to Consider:
Access Codes
If you are looking for the ability to add access codes for your kids and guests or to make sure the delivery gets into your home safely there are several options these locks accomplish this.
Some have them built-in and will include either push buttons or commonly a touchscreen that will light up as you approach.
The other option is to add a keypad accessory that is installed next to your door and communications to the lock.
The third is via the locks smart phone app which can act as a key for other users.
One thing to keep in mind is with a Bluetooth lock you will only be able to add codes when you are near the door and not remotely. If you are looking to manage your codes from a long distance you will want a lock that has either Wi-Fi built in or connects with a hub that does so that it can connect to your home router.
Integration with smart home ecosystems
Do you already have an Alexa, Apple TV or a smart home hub like SmartThings or Wink in your home?
Many of the smart locks on the market let you:
- Check status of your lock from your phone
- Lock and unlock the door using voice control
- Have your lock be a part of a "recipe" like a good night mode that turns off lights, locks door and sets security system.
Click on the buttons below to filter deadbolt locks by each of their compatible systems.
Additional Smart Lock Features
Smart locks also come with a range of other features that could be the deciding factor for your purchase.
Remote Locking
Check or manage your lock while away from your home
This feature is mostly driven by the connectivity options of the lock:
Bluetooth: No - Only within range
Wi-Fi: Yes
Zigbee and Z-Wave: Yes, via additional hub
Wi-fi Bridge: Many locks sell an additional Wi-Fi add-on that connects to your home router and enables this feature.
Proximity Locking
Automatically lock behind you or unlock as you approach
With this feature you can have your door automatically lock behind you after a certain amount of time (typically 30 seconds) or have it use your phone's GPS and Bluetooth to automatically unlock the door as you approach.
Fingerprint or Touchscreen
Use your fingerprint to open your door or a touchscreen
With this feature you can either open the door using an access code and a back-lit touchscreen or your fingerprint to securely open your doors.
Our Quick Picks
Out of all the smart deadbolt locks on the market we have selected a few of the top ranked models to get you started.
#1 Deadbolt Type: Complete Replacement
This type of lock will replace your entire deadbolt mechanism.
A few notes;
- Typically these locks will provide you with a new set of keys or backup keys in case your locks battery goes down or you don't have your phone on you.
#2 Deadbolt Type: Interior Replacement
This type of lock will replace just the interior portion of your deadbolt lock leaving the exterior in place.
A few notes;
- Typically with these type of locks you are able to keep your existing deadbolt keys so is perfect for those renting or don't want to deal with new keys for everyone.
- An added security benefit of this type is that you from the exterior of your home no one can tell that you have a smart lock enabled door.
#3 Deadbolt Type: Interior Attachment
This type of lock is built especially for you renters out there.
This lock uses heavy duty 3M tape to adhere to your existing deadbolt. A mechanism inside the smart lock attaches onto your lock's turning knob, then uses its motor to turn the knob and lock/unlock the door for you.
Deadbolt Smart Lock Comparison
AKASO Smart Lock
Finish Options: Black
Connectivity Options: Bluetooth
iOS App: Yes
Android App: Yes
- The auto lock feature automatically locks the door after 30 seconds whenever someone enters or leaves the building.
- The deadbolt feature prevents access from outside until it is securely released from the inside – a valuable security perk.
- “Low battery” alerts so you never run out of charge (if you do a backup 9v recharge system allows you to get in).
- Can use physical key or codes to get in
- Built-in intrusion alarm will sound during any lock tampering.
- The locking mechanism can be buggy and inconsistent, meaning the door sometimes remains unlocked.
- Access codes do not always work properly.
- Poor customer service means that problems can take a long time to resolve.
- Users must be within Bluetooth range of the lock to adjust any settings.
- No Wifi Access for remote locking from a distance.
- Lack of integrations with smart home ecosystems
- Uses 3rd part app
This AKASO model comes with all the standard smart lock features, including a 9V backup battery and smart key support. Mechanically the lock is strong and robust, and it’s very pleasing on the eye with its sleek black touchscreen surface.
Unfortunately, app integration is poor and secure codes sent to users don’t always work, and you can only change codes when you are within Bluetooth range making it unreliable for remote use.
Despite its mid-range price point, the lock suffers too many bugs to be a favorite over its similarly-priced rivals. If AKASO focuses on app integration and access code improvements, we could see a very polished product for their next release.
August Smart Lock 3rd Gen
Finish Options: Black and Nickel
Connectivity Options: Bluetooth and Wi-Fi Via Bridge/Hub
Google Assistant: Yes with add-on hub
Siri Support: Yes with add-on hub
Alexa Support: Yes
iOS App: Yes
Android App: Yes
- Ridiculously easy install with only a screwdriver, plus helpful videos if you get stuck.
- Perfect option for renters because you keep your own keys and it doesn’t change the look of the exterior.
- Sturdy, high-quality build with solid metal exterior.
- The app is easy to configure and use.
- Ability to give temporary digital keys makes this a great option for vacation rentals.
- The wifi bridge is sold separately, meaning none of the remote access features can be used until you spend the extra money.
- The auto-lock feature makes it too easy to lock yourself out if you’re just stepping out for a moment, however it can be disabled.
- Spotty connection for auto-unlock, especially for those using Android.
- Locks and bridges are 1:1, so if you’re outfitting multiple doors, it can get expensive.
August has clearly taken customer feedback to heart and applied everything they’ve learned to the August Smart Lock 3rd Generation. It does everything you could want from a smart lock. Run out the door in the morning and let it auto-lock behind you, remotely send the babysitter a temporary key, have the door auto-unlock as you approach so you don’t have to stop and search your pockets, or tell Alexa/Google to lock your door at night rather than getting out of bed to double check.
The cherry on top is that it does all of this without modifying the look of your home or requiring you to change the locking mechanism.

- Larger than the base model, so it can cause issues when there is a tight fit (measure first!)
The August Smart Lock Pro 3rd Generation is all about seamless integration with the rest of your smart home. If this is the only smart product you ever plan on buying, save the extra money and get the base model. Otherwise, only the pro lets you connect through Z-Wave Plus, Siri, and Homekit (both support Alexa and Google Home).
Like the base version, you can use the app to tailor how this lock functions for you. Enable and disable auto-lock or unlock features, view and control access remotely (as long as you have the Wi-Fi bridge), get low battery alerts, and know when the door is closed or locked.

Danalock V3
Finish Options: Nickel
Connectivity Options: Bluetooth, Wi-Fi Via Bridge/Hub, Z-Wave Plus, and Zigbee
Siri Support: Yes with add-on hub
Alexa Support: Yes
iOS App: Yes
Android App: Yes
- Four tailored versions for integration with popular smart home hubs: HomeKit & Bluetooth, Z-Wave & Bluetooth, Zigbee & Bluetooth, and Bluetooth-only.
- Simple installation and calibration, with extensive documentation to speed things up.
- A range of smart features including auto-unlock, twist assist, and geofencing
- Estimated 12 months battery life.
- Can be paired with the Danapad, a manual keypad enabling keyless entry for visitors – without downloading an app.
- Remote locking with versions that have Z-Wave or Zigbee and future integration with their to be released DanaBridge.
- No remote controlling options, though this should be corrected when the Danabridge V3 Plug launches this year.
- No native compatibility with Google Home or Amazon Alexa.
- Loud noise during locking and unlocking.
- Homekit version does not support auto-unlock or digital key sharing features.
The Danalock V3 is a good all-rounder in the smart lock game. There are four versions (Homekit, Z-Wave, Zigbee, and Bluetooth-only) so you can align it with your smart home setup. It takes 10 minutes to install, and the auto-unlock and twist-assist features make it feel truly ‘smart’. Danalock supports unlimited occupants and users can share digital keys to grant temporary access to visitors.
Unfortunately, the auto-unlock and digital keys features remain unavailable on the Homekit version. Combined with reports of inconsistent performance from buyers, the Danalock V3 falls just below our top-tier recommendations.

Gate Labs Camera Smart Lock
Finish Options: Nickel
Connectivity Options: Wi-Fi
iOS App: Yes
Android App: Yes
- Users can quickly change the passcode for your door from your phone.
- Track comings and goings by assigning unique pin codes to different people.
- Simple and easy to install, with the necessary tools and extra thickness adjusters arriving with the product.
- Unlock the door using the Android or IOS apps, or using the pin code.
- Features a hard key for backup in the event of failure or dead batteries.
- Can only lock or unlock manually when there is motion detected at the door.
- Can only view video when the motion detector is activated.
- Just installs on the deadbolt so if your lever/knob is a different color it could clash with its aesthetics.
- No night vision and the camera is affected by the glow from the LED lights.
- No video sharing or saving without a paid monthly plan (costs between $4.99-$7.99 a month)
The Gate Smart Lock is all about visibility and accessibility – for the right people of course! It includes a built-in camera, two-way audio and a pin number unlocking feature. Probably Gate’s strongest asset is the sheer number of ways it can be unlocked and of course the built-in video monitoring.
Whether using pin, smartphone app (IOS and Android) or the old-fashioned back-up hard key, you’ll never have to worry about being locked out. Assign different pins to different people, and record who has accessed your door at what time: perfect for offices or multiple occupancy houses (note: scheduled access codes require an add-on monthly service).
Integrations with other smart home systems like Alexa, Siri and others is non-existent so is a good choice if you are looking just for a smart video door lock without having to buy a lock and video camera or deal with other integrations headaches with smart home hubs or home security services this could be a good choice for you. If these are important to you would suggest you look at other locks.
An important note If you want to have scheduled access or video sharing and saved history you will have to upgrade to a paid monthly service plan starting at $4.99 a month.
Kevo Contemporary 2nd Gen
Finish Options: Black, Bronze, Chrome, and Nickel
Connectivity Options: Bluetooth and Wi-Fi Via Bridge/Hub
Alexa Support: Yes with add-on hub
iOS App: Yes
Android App: Yes
- Wide range of finish options
- Touch to open with proximity technology
- Unlimited ekeys with Anytime, 24 hour access, scheduled and an activity log of all access
- Integration with a fair number of other connected devices including Alexa, Nest and Ring
- Responsive customer service with numerous users getting replacement locks
- Alexa integration only with the Kevo Plug added Wi-Fi hub
- Customers have complained about inconsistent connectivity and tap to unlock.
- Users have complained about getting locked out of their house after unlocking the deadbolt inside before stepping out
- Complaints on battery life and being able to quickly change out the batteries once dead.
The Kwikset Kevo Contempory Model has several features going for it with its touch to open technology, add-on key fobs for additional users and options Wi-fi hub for remote monitoring and access and to connect with other connected devices like Alexa and your Nest thermostat.
From many user reviews it seems like the technology does not always match up to its promise with many users complaining about slow connectivity from their phone to the door, and overall being unreliable from both a hardware and app perspective.
On the positive users have praised Kwikset for their customer service with people receiving replacement units and help walking through issues.
If you choose to add the Wi-fi hub this opens up more possibilities and users have positive results when using together with the lock.
Bottom line is that while Kwikset continues to improve on the model lineup each generation you will find more bang for your buck somewhere else until they fix all of the kinks.

Kevo Convert
Finish Options: Bronze and Nickel
Connectivity Options: Bluetooth and Wi-Fi Via Bridge/Hub
Alexa Support: Yes with add-on hub
iOS App: Yes
- Lets you keep your existing keys
- No visible exterior signs that you have a smart lock installed.
- Customer service is high from Kwikset
- Constantly refining app software for complete Kevo lock line-up
- Wide range of eKey options with scheduled, 24 hour and unlimted access for family members.
- Key fob and Wi-fi hub integration for added smart home device and Alexa compatibility and backup option.
- Users complain of slow connectivity between app and lock
- Doesn’t have a tap to unlock feature like the other locks in the Kevo lineup
- Customers have noted they don’t trust the lock so always keep their key on them anyway.
The Kevo Convert offers renters and those wanting to keep their smart home capabilities discrete a budget option.
The model uses the same app as the other Kevo devices and users enjoy the eKey capabilities as well as the add-on key fobs and Wi-fi hub that allow you to open and unlock your door using Alexa and tie in with your Ring doorbell, Nest thermostat and other smart devices.
Unfortunately, app response time is slow, and you can only change codes when you are within Bluetooth range making it unreliable for remote use without the $99 extra hub.
Overall the Convert suffers from the same reliability issues as the others in the line-up and until Kwikset fixes these issues with the connectivity it is best to look elsewhere unless the eKey and ability to keep your own physical keys is the main selling point for you.

Kwikset 910
Finish Options: Bronze, Chrome, and Nickel
Connectivity Options: Z-Wave, Z-Wave Plus, and Zigbee
Alexa Support: Yes with add-on hub
iOS App: No
Android App: No
- Plays well with top ranking smart home hubs like Wink, SmartThings and Vera
- Wide range of finish and style choices
- Backed by solid Kwikset warranty
- Integrated with wide range of Z-Wave or Zigbee security systems like ADT, Alarm.com with many users saying this is the best feature.
- No dedicated smart phone app so any app integration will come from your smart home hub like SmartThings app
- Cannot set new access codes remotely
- A few user complaints on battery life and build quality.
The Kwiset 910 could be a great fit for you if you are looking for basic access codes access for your family (up to 30 total) or are already using a Zigbee or Z-Wave smart home hub or security offering.
The majority of the “smart” lock capabilities are only enabled if you have a hub or security system since the lock does not have a dedicated app on its own.
Once you are connected to your hub or smart security system like ADT or Alarm.com you will use their integrations to control and check on the door status or initiate a remote locking action or routine. If you want Alexa or voice control out of the box you should look at other options.
Additional pros include the number of available options and finishes from contemporary or traditional style along with the Signature series which removes the keypad while allowing you to hide the fact your door is smart lock enabled.
Bottom line is if you are looking for simple code control along with possibility of integrating with the most popular smart home hub and security systems the 910 could be a good fit for you.

Kwikset 916
Finish Options: Brass, Bronze, Chrome, and Nickel
Connectivity Options: Z-Wave, Z-Wave Plus, and Zigbee
Alexa Support: Yes with add-on hub
iOS App: Yes
Android App: Yes
- Can work with Alexa if you already have a smart home hub like SmartThings or Vera setup in your house.
- Users praise the easy installation process.
- Could be a positive or negative but you have to program codes directly on the lock itself for security reasons. Peace of mind for those security minded folks but not helpful if trying to use the lock to remotely manage codes or if wanting to use for Airbnb, etc
- Inconsistent battery life. Some users say they have used their batteries for multiple years where others only a few months. This also is impacted by how flush your door and lock mechanism is and how hard it has to work.
- If you dont have a smart home hub you are limited in that you cannot lock and manage the lock remotely. Also the hub integration allows you to lock the door and check its status but does not let you unlock the door or add new user access codes.
- Some users have complained about lock reliability with the lock failing to work reliably after a year or more of operation (Kwikset does have a very generous Warranty that should help offset concerns on this front)
- Changing batteries can be a bit of a hassle with the battery pack area being more difficult to access than it should be.
- The SmartThings app only controls basic locking and unlocking. For more advanced features a developer app is required so out of the box you won’t be able to unlock all functionality through the standard app.
- No a huge deal but the 4 AA batteries are not included.
The Kwikset smart lock is a decent tool for homes that are looking for basic smart lock functionality and becomes a much better choice if you already have a Zigbee or Z-Wave smart home hub in your home.
Features like pin access codes, auto-lock and a touchscreen panel come out of the box. If you don’t already have a smart home hub than we suggest you look elsewhere for locks with more features at a similar price point.
If you do have a smart home hub than the door opens up more options like Alexa integration (Siri/Homekit not supported) and features like setting automation schedules or integrations with other settings like turning off your lights when at the same time as locking your door.
Even with a smart home hub their are a few things to be aware of with the 916, you can not add new access codes remotely or unlock the door remotely. This is done for security reasons. If you really need this option we recommend looking at another lock.
Overall the 916 is a mid-range priced lock with mid-range features. it wont win any awards but could be a functional winner for you if you are looking for basic smart lock functionality from a reputable company.

Kwikset Obsidian Smart Lock
Finish Options: Black and Nickel
Connectivity Options: Z-Wave Plus and Zigbee
Alexa Support: Yes with add-on hub
iOS App: No
Android App: No
- The sleek obsidian color and design will fit in to any home.
- Can easily install onto the existing deadbolt in a short amount of time.
- SecureScreen patented technology prevents dirty fingerprints lingering on-screen and revealing your pin code.
- Connected version gives you 30 customizable user codes so family and friends can gain access.
- Users can plug in a 9V battery for backup power in case of failure.
- No backup key included.
- Short battery life means they need replaced several times a year.
- Battery replacement is quite complex and unintuitive, with hard-to-remove battery casing.
- You cannot remotely add access codes from your smart home hub
- No standalone app (you use your Z-Wave or Zigbee connected hub like Smarthings or Wink)
Kwikset have created a stylish alternative to the conventional lock. For those prone to losing keys, the Obsidian Smart Lock provides a sleek alternative for a reasonable price. The patented SecureScreen technology is also a nice touch, making sure that your pin number isn’t revealed by grubby fingerprints.
Thirty customizable user codes make the Kwikset a great tool for multiple occupancy home. The lock’s only real weakness is a short battery life compounded by a hard-to-remove battery casing.
The lock comes with both Zigbee or Z-Wave plus connectivity so you can integrate with smart home hubs. The lock however does not come outfitted with a stand-alone mobile app so you are limited in what you can do like adding access codes remotely from your phone.
If you value style over practicality, however, then the Kwikset Obsidian is as attractive as they come!

- Assign up to 30 customizable codes to family and guests.
- Check the lock status of their door at any time using the Premis App.
- Full access data is recorded within the app.
- The Smartkey security features let owners assign, reassign, and cancel which hard key works with which Kwikset Premis smart lock.
- Installation is easy and takes less than an hour.
- All electronic communications are protected by Apple’s end-to-end encryption.
- Locking and unlocking using the touchpad can be very slow.
- The Premis App can be buggy, with long delays between app instructions and the door unlocking.
- AA batteries only last a few months.
- Full lock capabilities can only be obtained if you own a HomePod or 4th gen or up Apple TV
The Kwikset Premis lock is an incredible product when working correctly for those in the iOS / Apple ecosystem already and especially if you are already an owner of a HomePod or newer generation Apple TV.
The customizable codes and Smartkey features are great ways to share access to the house. Family friends and guests can now come and go without the need for spare keys under the doormat. With alarms for incorrect codes and a lock down mode you can also keep out would-be intruders.
However, the product is also frustrating. The unlock lag can leave you standing by the door for too long. On top of that, the poor battery life and buggy app mean the product doesn’t always perform as highly as it’s capable.
If these issues are resolved, the Kwikset Premis will be an even more formidable wireless lock for those committed to Apple devices and their security.
