Expert Reviews
Tested by tink expert

A great smart lock for anyone looking for a quick and painless upgrade for their standard single cylinder deadbolt. The August Smart Lock 3rd Generation's activity log shows you a timeline of everyone who's accessed the door and which action was performed. Guest codes are perfect for those who offer their home on a house sharing platform - give your guests a temporary code that expires after a given period of time. Although the lock only works via Bluetooth by default, using it with August Connect also allows for remote access over Wi-Fi.

Product Information

  • No locksmith required: Installing the August Smart Lock 3rd Generation is painless. You can perform a simple retrofit installation on any standard single cylinder deadbolt - all you need is a standard Philips screwdriver. You can even continue to use your regular keys as normal.
  • Auto locking: The lock uses Bluetooth to connect with your smartphone, recognizing when you're within the range of the smart lock. It then locks and unlocks the door depending on your presence, allowing for keyless entry.
  • Grant temporary access: The days of stuffing a spare key underneath a plant pot are over! You can share temporary keys via the app. This can be using a one-off key, or a key available at a certain time each day for people such as construction workers, babysitters or your Airbnb guests.
  • Activity log: Included in the app is an activity log that shows you who accessed the door and when, as well as the action that was taken (door opened, locked, unlocked). This can be a great feature for customers who want to keep an eye on their elderly family members.
  • For all your devices: You can use the same app to access all of your August devices - including the August Connect, August Smart Keypad, August Doorbell Cam Pro, and August Smart Lock Pro. You can control your entire home security network from one location.

The August Smart Lock, 3rd Generation in action

A smart lock that you can install completely by yourself and which lets you keep your existing locks and keys. The 3rd Generation of the August Smart Lock can be retrofitted over an existing deadbolt lock.

Is the August Smart Lock compatible with my home?

It's important to ensure that you have a door lock which is compatible with the August Smart Lock. The smart lock is compatible with most-single cylinder deadbolts, the most common type of lock found in North America. These are identifiable by the fact that they work with a single cylinder deadbolt that operates with a key on the outside and a thumb turn on the inside. The deadbolt and door handle are also separate. The Bluetooth lock is not compatible with Mortise style locks (often found in apartments), rim cylinder locks or interconnected locks.

You can also ask either the Google Home or Amazon Alexa voice assistants to lock your door or check the status of the door (voice-control requires that you also have the August Connect).
