Best Smart Locks that Support Amazon Alexa Android Central 2020

Making your home smarter seems to be all the rage these days. There are smart speakers, smart TVs, and other accessories that let you control your life with your voice. One of the most significant conveniences in a home can come from installing smart locks, so you never have to fish a key out again and can manage guests easier. These are the best smart locks that support Amazon's Alexa voice assistant, although our favorite is the August Smart Lock Pro, which is stylish, easy to install, and works with most smart homes.

Best Overall: August Smart Lock Pro

The Smart Lock Pro is a stylish lock that works with most existing deadbolts, meaning you don't need to replace your keys to use it. You can lock and unlock the door with an Alexa command, or the door can automatically unlock as you approach it with your smartphone. It supports smart home standards like Z-Wave Plus and Apple's HomeKit, and includes a Connect bridge that allows it to work over Wi-Fi. That included bridge is key to this pick's value, as many other connected smart locks require you to purchase a hub separately.

We also like the 24/7 activity feed, so you can see when your door and lock have been in use, as well as the ability to grant keyless access to anyone you wish. This lock talks with Alexa to let you know when you need to replace its batteries, which can be set up for automatic reorder on Amazon.com.

About the only real complaint we've heard with this device is that the auto-lock feature can be a bit finicky at times, often engaging when an owner is merely heading out to the curb to take out the trash, or even if the door isn't completely closed. It also requires a separate bridge to work with Alexa.

Pros:

  • Sleek, modern styling
  • Available with Wi-Fi bridge
  • Door Sense lets you know the door is securely closed
  • 24/7 activity feed
  • Works with existing lock and keys

Cons:

  • Does require a bridge to work with Alexa
  • Auto unlock feature can be finicky
  • The look may clash with some homes/doors

The standard Smart Lock doesn't support HomeKit, even when attached to an August Connect (which isn't included). However, it works just fine with Alexa for considerably less than the Pro. You can create guest "keys" for friends' phones with a set expiration date, which makes it an ideal choice for Airbnb hosts or anyone who doesn't want to give out a physical key.

Like its more expensive sibling, this smart lock works with your existing lock and keys, so you don't have to replace them, and it also features Door Sense technology to let you know if your door is open or closed. Best of all, it will lock automatically when you leave, and unlock when you arrive back home.

Just be careful — if multiple users are coming in and out of the home, you could get locked out if you don't have your smartphone with you. Also, some users have noted that the mechanism can be quite loud, so don't count on this to cover for you when you sneak in late.

Pros:

  • More affordable than the Pro
  • Door Sense technology
  • Easy to create and share guest keys
  • 24/7 activity feed

Cons:

  • August Connect bridge not included
  • Auto-lock can be tricky with multiple users
  • Locking mechanism can be quite loud

Smart, yet simple

The August Smart Lock gives you many of the features of the Pro model, at nearly half the cost.

Modern Keypad: Schlage Connect Touchscreen Deadbolt

If you leave your phone at home, having a backup way to get in is essential. A physical key is always smart, but a PIN may be more convenient. With the Schlage Connect, you can lock and unlock your door with Alexa (with a hub, sold separately), and the touchscreen is fingerprint-resistant so that you won't give away your PIN. You can also set up alerts to tell if someone is trying to tamper with the lock or force their way inside. While this model does not work with the Amazon Key service, Kwikset offers several compatible models.

The device is simple to install and will let you know when the battery is running low with more than enough notice to order more. Schlage is known for its hardware prowess, and this device is no exception. It's made to ANSI Grade 1 standards that meet the highest levels of durability and security. As you might expect for such a solid piece of hardware, the locking mechanism can be pretty loud, and the interior panel may take up a bit more space than you'd expect.

Pros:

  • Matte touchscreen hides fingerprints
  • easy access without keys or phone
  • ANSI Grade 1 security rating

Cons:

  • Requires a separate hub
  • Loud mechanism
  • Relatively large device

Most Futuristic: Lockly Secure Pro Deadbolt

This unique smart lock offers extra security by scrambling the location of the buttons each time the screen turns on. You won't be able to rely on muscle memory to input your code, but that also prevents would-be thieves from easily determining which numbers to press. There's also a fingerprint reader on the side of the unit that can remember up to 99 unique prints. With all these fancy features, this lock makes you feel like a spy.

Lockly's app is intuitive and easy to navigate, and you'll have no problem sharing access with guests, adding approved fingerprints, or checking on the battery status of the device. It's nice to know that the Wi-Fi hub is included with purchase, and you don't have to worry about ordering one separately.

As much as we love this smart lock, there are a few downsides to it. For one, it's one of the more expensive options we've come across. Also, the touchscreen smudges easily and it doesn't get very bright, which can make inputting your code tricky in direct sunlight.

Pros:

  • Dynamically changing keypad
  • Fingerprint reader
  • Wi-Fi hub included
  • Stores access history

Cons:

  • One of the more expensive options
  • Touchscreen can get smudgy
  • Cannot increase touchscreen brightness

Tried and True: Yale Assure Lock

Yale Assure Touchscreen Lock LifestyleSource: Yale

When you picture a traditional smart door lock, the Yale Assure is probably what you have in mind. It works perfectly with Alexa — with the additional purchase of a hub — and you can manage the lock from anywhere. It can remember 250 unique PIN codes, so you can assign codes to guests without giving out our master PIN. You can also lock every code out of the system at once just in case something goes wrong. There are two physical keys included if you need them as well, and installation only takes a few minutes and a screwdriver. This lock is also equipped to work with the Amazon Key service.

This model comes with just the lock, but if you prefer to update your whole hardware setup, you can purchase bundles with various types of door handles in different styles and colors. This lock is weather resistant and comes with two physical backup keys should you forget your code or something goes amiss. Perhaps best of all is that this device is quiet, unlike many other locks on this list.

Pros:

  • Stores up to 250 unique pin codes
  • Simple tap to lock
  • Comes with two physical backup keys
  • Quiet, motorized deadbolt

Cons:

  • Requires a separate hub
  • Auto-lock only works from outside

Modern Day Classic: Schlage Encode Smart Wi-Fi Deadbolt

This lock has a lot in common with the Yale version above but sports a more practical, Spartan look. It's available in four traditional colors, including bronze, chrome, and nickel, but in my opinion, the matte black is the best-looking option.

The lock features built-in Wi-Fi, so it doesn't require a hub. Its surface is resistant to fingerprints so that it won't give away your passcode pattern. It also works with the Amazon Key program, so that you can pair it with connected cameras to see who is coming and going, as well as grant access to trusted visitors and vendors. While it does support these features, you can't get it to unlock automatically with your device based on your proximity to the door.

Amazon is currently offering a bundle paired with an Echo Dot, so if you don't currently have an Alexa-enabled device, or if you're looking to pick up an extra, this could be a good value for you.

Pros:

  • Works with Key by Amazon
  • No hub required
  • Smudge-free keypad
  • Available in a bundle with Echo Dot

Cons:

  • Pricey
  • No auto-unlocking feature

Best Hybrid Lock: Kwikset Kevo Convert

Like the August locks, the Kevo Convert only replaces your interior lock, meaning you don't have to replace your keys, making it perfect for rental homes. It automatically unlocks when you approach it, and it can automatically lock after 30 seconds. If you purchase the Kevo Connected Hub, you'll be able to operate the lock with Alexa, too. You can get notifications when guests access the door, and you can set it up with the Kevo 2 smart lock for no-touch open-door entry. You can also send eKeys to your guests' smartphones, or lock any guest out remotely.

While this model does not work with the Amazon Key service, Kwikset offers a version of the Kevo Convert, as well as several other models that are compatible. Unlike other options, the Kevo Convert can work with deadbolts from Kwikset, Weiser, Baldwin, or Schlage, making it an even more versatile option.

Pros:

  • Easily converts dumb locks to smart ones
  • Works with Kwikset, Weiser, Baldwin, or Schlage deadbolts
  • Very affordable
  • No-touch to open compatibility

Cons:

  • Requires a hub to work with Alexa
  • Need a Kevo 2 smart lock for no-touch open feature
  • Need smartphone to unlock it

The Kevo Convert is a brilliant option for those who don't want to spend a ton of money on a smart lock system.

Bottom line

Many of the best smart locks can work with Amazon's Alexa voice assistant, but hands-down, our favorite is the August Smart Lock Pro. It may be on the pricey side, but it supports a wide range of smart home standards, works without replacing your external lock, and looks fantastic.

Some of these smart locks from manufacturers like Yale, Kwikset, and Schlage work with Amazon's Key service, which connects specific smart cameras, security systems, doorbells, and smart locks. It allows you to see and grant access to your home. However, the Amazon Key service requires that you purchase a pre-set security bundle (or buy the items a-la-carte), which can be a pricey proposition.

Note that many of these smart locks will require the purchase of batteries and a hub, so be sure to factor that into your purchasing requirements. All in all, you can't go wrong with one of the smart locks on this list if you're looking to get set up with Alexa!
