What do you get if you add some smarts to your door lock? A smart lock that makes your home more secure and more flexible. You can be notified when people get home, let people in without a key, and generally have more control over who comes and goes in your home. For the ultimate in safety and security, combine your smart lock with a compatible video doorbell and you'll be able to see who is at the door and let them in if you want to.

After spending more than 30 hours evaluating and testing a dozen models, we found that the best smart lock overall is the August Smart Lock Pro, which is easy to install, easy to use, and supports all of the major smart home systems, such as Alexa and Google Home. The Pro looks attractive and doesn’t replace your old lock cylinder, so you don’t have to swap out your old keys.

For those who want a smart lock on a budget, the August Smart Lock is our top pick. It’s significantly cheaper than the Pro version, but has most of the same features, with the only major omission being HomeKit support. However, you’ll want to also purchase the August Connect to link it to your Wi-Fi network, so that you can monitor and control the lock remotely and link it with other smart-home devices.

Those who want a lock that can be opened without a key will like the Kwikset Obsidian, a simple, straightforward lock that uses a code rather than a key. The device has a clean, simple design that looks great on a home office door or storage space. The Kwikset has only basic smart home connectivity, though: you’ll need a Z-Wave hub to trigger it remotely.

1. August Smart Lock Pro Connect

Best overall smart lock

Rating: 4.5/5 stars

Lock Type: Deadbolt | Smart Home Compatibility: Alexa, Google Home, Apple HomeKit | Connectivity: Wi-Fi, Bluetooth, Z-Wave Plus | Number Pad: Optional | Alarm: No | Codes: Unlimited | App: Yes

Pros: Easy to install; works with HomeKit, Alexa, Google Assistant, Z-Wave, Nest, IFTTT and more; convenient Auto-Lock and Auto-Unlock features

Cons: No alarm, no Amazon Key support

The August Smart Lock Pro Connect has it all. This lock is compatible with all of the major smart-home platforms, so you can open it with Alexa, Google Assistant or Apple HomeKit; it also looks great, although the circular back of the lock may confuse some users. The device is easy to install on most single-cylinder deadbolts. The app is easy to use and simply allows you to add additional users who can open the door without a key. For those who don’t have a phone, the optional $60 August Smart Keypad provides another way to get in without a key.

The August Smart Lock Pro Connect is also the best smart lock for landlords and Airbnb hosts, as it offers a hassle-free way to let your guests in and know when they have left. The lock integrates directly with the Airbnb booking system, so you can give your guests a virtual key when they book, with the confidence that it will only work on those dates. When the visitors have checked out and left, the app will notify you, so that you can ready the unit for the next guest.

2. August Smart Lock

The best smart lock value

Rating: 4.5/5 stars

Lock Type: Deadbolt | Smart Home Compatibility: Alexa, Google Home | Connectivity: Bluetooth, Z-Wave Plus | Number Pad: Optional | Alarm:No | Codes: Unlimited | App: Yes

Pros: Easy to install; works with HomeKit, Alexa, Google Assistant, Z-Wave, Nest, IFTTT and more; flexible settings; Auto-Lock and Auto-Unlock features

Cons: August Connect module sold separately; no Apple Homekit nor Amazon Key support

If you want to add some smarts to your home without spending too much, the August Smart Lock has most of the features you'll need, at a reasonable price. You can pick up this smart, full-feature lock for $132.

If you rent your home, the August Smart Lock is our top pick, as it’s very simple to install on top of an extant deadlock without replacing the cylinder or key. There’s no need to replace the cylinder; it will continue to work with your existing keys, keeping your landlord happy. And, when you move out, you can quickly and easily remove the lock and replace it with the old one, keeping your deposit safe.

Note that you will also need the $65 August Connect module if you want to control and monitor the lock remotely. That module can handle multiple locks, so it’s a great low-cost pick for adding remote control to several doors at once. The only thing missing is support for Apple Homekit.

3. Schlage Encode

A great smart lock with a built-in alarm

Rating: 4.5/5 stars

Lock Type: Deadbolt | Smart Home Compatibility: Alexa, Google Home | Connectivity: Wi-Fi, Bluetooth | Number Pad: Included | Alarm: Yes | Codes: 100 | App: Yes

Pros: Works with Alexa, Google Assistant & Home; Supports Amazon Key; simple installation and setup; built-in alarm

Cons: No support for Apple Homekit

If the local Amazon delivery person is always around, you need the Schlage Encode. As well as being a great combination of a manual, keycode and remote-controlled lock, the Schlage Encode supports the Amazon Key service, which allows an Amazon delivery person to open the door when they arrive and place your packages inside the house. That feature makes them less likely to be stolen. Amazon Key does require a compatible security camera, which costs extra. The lock supports Alexa and Google Assistant, so you can integrate it with your Smart Home system easily, but there is no support for HomeKit.

4. Yale Real Living Assure SL

Top keyless lock

Rating: 4.5/5 stars

Lock Type: Deadbolt | Smart Home Compatibility: Alexa, Google Home, Homekit, SmartThings | Connectivity: Bluetooth, Zigbee, Z-Wave Plus | Number Pad: Yes | Alarm: No | Codes: 250 | App: Yes

Pros: Support for Amazon Alexa, Google Home and Apple HomeKit; attractive, simple design

Cons: Touch screen sometimes takes a couple of touches to respond

The support for multiple smart home standards is the standout feature of the Yale Real Living Assure SL; it works with Alexa, Google Home, HomeKit and SmartThings. That means you can control it from your iPhone, your Amazon Echo, your Android phone, or Google Home. Plus, it has an attractive, well-designed lock that is easy to install. There is no manual key option, though: it’s a keycode, app or nothing. If the battery runs out, you can give it a temporary boost by touching a 9v battery to two contacts underneath the keypad.

5. Lockly Secure Plus

Best smart lock with fingerprint reader

Rating: 4/5 stars

Lock Type: Deadbolt or lever | Smart Home Compatibility: Lockly | Connectivity: Bluetooth | Number Pad: Included | Alarm: No | Codes:Unlimited | App: Yes

Pros: Lock can be opened with a fingerprint: includes a manual lock

Cons: Can’t unlock remotely without buying WiFi adapter; no built-in support for Alexa, Google Home or Homekit

With the Lockly Secure Plus, the only key you’ll need is your finger; one touch to the fingerprint reader on the right side of the lock body opens the lock. You can also open the door by entering a code, and cleverly, the touchscreen keypad shifts the numbers around, so thieves can’t guess your code by looking at finger smudges.

Another unusual feature is that the Secure Plus is a lever lock; most smart locks are deadbolts. However, the Locky Secure Plus doesn’t support other smart home systems. For that, you'll need either a $70 Wi-Fi adapter, or to spring for the $299 Lockly Secure Pro, a separate model with built-in Wi-Fi that lets it connect to Alexa and Google Home.

6. Nest X Yale

Keyless Google Assistant smart lock

Rating: 4/5 stars

Lock Type: Deadbolt | Smart Home Compatibility: Google Home & Assistant, Nest | Connectivity: Bluetooth, Wi-Fi | Number Pad: Included | Alarm: No | Codes: Unlimited | App: Yes

Pros: Simple installation process; integrates with other Nest devices

Cons: No support for Amazon Alexa or HomeKit

“Google, lock the front door.” If you are a Google household, you want a lock that speaks to the Google Assistant smart home system. Our pick for this task is the Nest X Yale, a neatly designed lock that works very well with Google Assistant. Locks from August and Schlage also support Google Assistant, but the Nest X Yale is the more elegant, all-in-one solution if you are invested in the Nest or Google Assistant systems.

7. Kwikset Premis

A simple Apple HomeKit deadbolt

Rating: 3.5/5 stars

Lock Type: Deadbolt | Smart Home Compatibility: Homekit | Connectivity: Bluetooth | Number Pad: Yes | Alarm: No | Codes: 30 | App: Yes

Pros: Support for keycodes and remote operation; support for Apple Homekit; rekeyable lock allows you to change keys

Cons: No support for Alexa or Google Home; no Android app

The Premis is a smart, simple lock for those who want to offer entry with keys, codes and a smartphone app. The low-profile keypad looks smart, but still offers a manual key option for the luddites in your house; Homekit support means that you can control it through Siri or the Premis app. The latter also allows you to create keycodes that provide limited access, such as allowing the dog walker in during the day, but not at night. There is no support for Amazon Alexa, Google Assistant nor Google Home, though, so you can’t check the lock from your Amazon Echo.

8. Kwikset Obsidian

Minimalist keyless smart lock

Rating: 3.5/5 stars

Lock Type: Deadbolt | Smart Home Compatibility: Z-Wave | Connectivity: Z-Wave | Number Pad: Included | Alarm: No | Codes: 30 | App: Yes

Pros: Clear installation process; clean, striking design

Cons: Sometimes takes a few touches to respond; requires Z-Wave hub to work with Alexa, Google Assistant

You’ll never forget your keys with this lock, because there aren’t any. The Kwikset Obsidian with Home Connect is a keycode, deadbolt lock with a smart, minimalist keypad that lights up on touch. Tap in a code (it can hold up to 30) and the lock opens. Using the Obsidian is a simple way to control access to a basement or home office without worrying about keys.

A feature called SecureScreen prompts you to touch random digits before you enter your code, so others can’t guess your code by fingerprint smudges. However, in order to control or monitor the lock remotely, you’ll need a compatible Z-Wave hub, such as Samsung SmartThings. If the four AA batteries run out at the wrong moment, you can give the lock a boost by touching a 9V battery to the two terminals underneath the touch panel.

    Thanks for sharing this helpful information about smart locks on the market. All the smart locks you have described above are very secure and their features are awesome.
  • stkelly612
    Is there any of these that would maybe be able to provide a Bluetooth alert to a phone if tampered with? I want to use one of these on a closet door as a gun safe of sorts, but would be great to know if someone (kids) are screwing with it.
  • REMOTIZER
    I enjoy tapping my key fob velcroed to my car's visor as I pull into my driveway. My front door's key fob uses RFID, similar to the key fobs cars and garage door openers have used for decades. At DEF CON 2016, they proved just how easy it is to hack a Bluetooth or "IP" enabled "smart locks". At under $50, I've enjoyed mine since 2005.

    Schlage Connect does have an App for local interface. I use a Wink 2 Hub for remote access with the Wink app.

    What do you think about the Ultraloq UL3 BT: https://goo.gl/WB8fjt ?

    All of these (minus the padlock) are deadbolts, what about non deadbolt locks? I need a regular door handle smart lock. The one linked above seems to be the best I can find but I am disappointed that it can't be remotely accessed (from work, not Bluetooth range).

    I know they say they are rolling out a bridge for the device but that's not until October, best case scenario and costs another 50 bucks and needs a power outlet.

    I'd really love a smartlock with the following specs:
    1. Weatherproof (for outside door)
    2. Regular door handle/knob, no deadbolt (for garage/building door)
    3. Fingerprint + Pinpad
    4. Remote accessible

    Can you recommend something better than the above?

    We haven't tested them yet, but here are several options from Schlage, Kwikset, and Yale that may fit your criteria:

    Thanks. I like the last one. It's $240 and doesn't have fingerprint readers though. Hmmmm. Thanks for the reply.
  • johnavil
    Of all the top three locks, the August wins it hands down for me. The fact that is has an app and unlimited codes seals the deal. PLUS I don't have to put an ugly keypad lock on the outside of my door. The Smart lock mounted to the inside of my front door in less than 15 minutes. I was even surprised that I didn't have to drill any new holes. The only thing that took a while was for me to figure out that the round panel was held on with magnets and that's where the batteries were.

    Other than that. It's super sleek, simple and linked with my Alexa and Apple homekit easily.

    I can't post links.


    What's wrong? Anyway, if you check out that link. You will see this:

    if you use APP, your password and all your private door security information will be upload to the web server. So it is providing a very good chance for the bad guys to hack the server and get all your info. And the APP admin can get all your door opening information. And if you lost phone, your house would be insecure, because someone may use your phone to open door.

    And other information.
