These are the best smart locks that you can use with Alexa

Modern chic

August Smart Lock Pro + Connect

Staff pick

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.

Smart yet simple

August Smart Lock

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.

Tamper alerts

Schlage Connect Touchscreen Deadbolt

If you leave your phone at home, having a backup way to get back into your house 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.

Fingerprint reader

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 kind of makes you feel like a spy.

Touch sensitive

Yale Assure Lock

The Asure Lock 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.

Traditional approach

Kwikset SmartCode Deadbolt

A more conventional-looking option, the Kwikset SmartCode Deadbolt uses regular old buttons to authenticate users. As with the other options, you can control it with your voice with Alexa, provided you purchase a hub. It supports up to 30 unique codes, and if you forget to lock the door, it will automatically lock itself after thirty seconds. The lock operates on four AA batteries, though these are not included. While this model does not work with the Amazon Key service, Kwikset offers several compatible models.

Great for renters

Kwikset Kevo Convert

Like the August locks, the Kevo Convert only replaces your interior lock, meaning you don’t have to replace your keys — 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 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.
