I review smart locks for a living — these are the 5 best Black Friday deals

August Wi-Fi smart lock: was $229 now $169 @ Amazon
Our favorite smart lock overall has been marked down by 26%; we love its ease of installation as it converts the interior half of your deadbolt without replacing your exterior lock. It automatically locks and unlocks your door and works seamlessly with every major smart home system. Best of all, you can still use your original door keys.

Aqara U100 Smart Lock: was $229 now $132 @ Amazon
The Aqara U100 Smart Lock is loaded with ways to access your home like a built-in fingerprint scanner, keypad app or mechanical key. Plus, you can unlock with your iPhone or Apple Watch, even if they're out of power. 

Yale Security Assure Lock 2 with Wi-Fi: was $239 now $151 @ Amazon 
The expansive support for multiple smart home standards makes the Yale Assure Lock 2 one of the best smart locks available. It works with Alexa, Google Home, HomeKit and SmartThings and most importantly Matter.

Schlage Encode Plus: was $330 now $299 @ Amazon
The Encode Plus has a higher price than the other smart locks I've tested, but it's also far more durable. It has the highest ANSI rating for locks to withstand heavy strikes and over 200,000 deadbolt cycles. This model has the same features as the competition but stands above it for its Apple HomeKey support. You can unlock the door just by pressing your Apple Watch (or iPhone) against it.

eufy Security Smart Lock C220: was $149 now $99 @ Amazon
Your finger is the only key you’ll need for Eufy's smart lock. While it's the fastest way to get in (at under 0.3 seconds), you can also open the door by entering a keypad code, through the app or using a smart assistant. Its anti-peep keypad adds random digits so thieves can’t guess your code.

ULTRALOQ U-Bolt Pro: was $249 now $148 @ Amazon

Sleek yet secure this lock is jam-packed with smarts. Ultraloq's web management app lets you control and check the status of your door remotely from any PC or tablet. It automatically locks and unlocks your door based on its built-in sensor and lets you know if your door is left ajar. Plus its fingerprint reader is highly accurate but has a large sweet spot for you to throw a digit over it from a variety of angles.

Lockly Flex Touch: was $189 now $106 @ Amazon

If you don't want anyone to know you have a smart lock, the Lockly Flex Touch is for you. Its fingerprint reader sits just below the lock hidden from view. Beyond app control, it can store up to 99 fingerprints and works with a traditional key. However, you'll need a smart home hub to control it remotely over the internet.
