Upgrade your door with the Assure Lock SL, the slimmest smart lock on the market with a touchscreen keypad for key-free entry. The lock comes with the Connected by August Kit that allows you to lock or 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 (with the included August DoorSense installed)! Plus, you can lock, unlock or check current status with voice assistants including Amazon Alexa, Google Assistant or Siri. The lock is 100% key free meaning its tamper proof and there's no keys to lend or lose. It features a backlit touchscreen keypad so even when you don't have your phone, you can unlock your door without the hassle of keys. The Assure Lock is super easy to use and installs in minutes with just a screwdriver on standard doors (1-3/8" to 2-1/4" thick).
