Upgrade your door with the Assure Lock, a smart lock with a sleek touchscreen keypad for key-free entry. The lock is Connected by August allowing you to lock/unlock, share access and see who comes and goes all using your August app, from anywhere! For ultimate convenience, your Assure Lock will unlock automatically as you approach the door and it will relock once the door is closed! Plus, you can lock, unlock or check current status with voice assistants including Amazon Alexa, Google Assistant or Siri. The lock features a backlit touchscreen keypad so even when you don't have your phone, you can unlock your door without the hassle of keys. It's super easy to use and installs in minutes with just a screwdriver on standard doors (1-3/4" to 2-1/4" thick).
