This advanced Smart lock, which is compatible with Alexa, offers an array of advantages over traditional door locks. It's furnished with high-tech features like remote access, proximity auto-unlock, security notifications, and voice-controlled functionality. These unique features set it apart from its competitors. The innovative technology it utilizes revolutionizes the accustomed use of physical keys, creating a more streamlined and effective system for door access and security.

I've spent a lot of time researching and testing smart devices including smart locks over the last number of years. 

I have the Yale Wi-Fi smart lock in my holiday home which has been a great addition. I no longer need to hide a key in the garden as I can simply give my friends a personalized passcode for them to use when they come to visit while I'm away.

Below are my top picks for the best smart locks that integrate with Alexa.

2023 Update: I've removed both Eufy and Wyze smart locks from this list due to recent security issues that both companies have faced.

Top Things to Consider Before Choosing an Alexa-Compatible Smart Lock

Smart locks are a secure way to control access to your home. With Alexa compatibility, you can conveniently lock and unlock your door with just a voice command. In this section, I'll walk you through the top things to keep in mind when purchasing a smart lock with Alexa voice control.


Before purchasing a smart lock, it's important to determine whether it's compatible with your existing door hardware. All of the locks listed here work with most standard single-cylinder deadbolts and most can be DIY installed. However, if you have a double-cylinder, vertical-cylinder, mortise, or integrated lock, you will likely need a more specialist smart lock. I also recommend double-checking measurements first, in case modifications to your door are needed.

Security features

Security should always be a top priority when selecting a smart lock. Look for features like two-factor authentication, strong encryption, and industry certification to keep your home and family safe. For example, Ultraloq has ANSI Grade 1 certification.

Battery life

Smart locks are powered by batteries, so be sure to choose one with a long battery life. Look for a lock with a rechargeable battery or one that sends notifications when the battery is running low.

My experience of smart locks is that most of them burn through their batteries quickly requiring constant replacements. Also make sure the lock you pick has a backup power option, to avoid being locked out!

Remote access

Smart locks allow you to control access to your home from anywhere with an internet connection. Make sure the lock you choose allows you to remotely monitor and control the lock. If the lock has a keypad, you should have the ability to set a number of different codes that you can then activate and deactivate.

Smart Home Integration

If you already have a smart home, look for a lock that integrates well with the devices you already own. This integration makes it easier to automate and customize the control of your smart home. For example, you can trigger a security camera to record when the lock is being used. Or you can trigger sirens, lights and music to play if a tamper is detected.


Smart locks can be expensive, so make sure to choose one that fits your budget. The price of a smart lock depends on its features, so consider which features are most important to you before making a purchase. At the time of writing, the Lockly was the most expensive on our list while the Switchbot was the cheapest.
