Conveniently secure your front door with or without a key by replacing your old standard deadbolt with the Yale Zigbee Push Button Deadbolt Assure Lock. This electronic, motorized deadbolt offers a pushbutton keypad on the outside and a thumbturn on the inside, as well as a traditional keyhole. To lock/unlock the door, input your 4-8 digit code into the pushbutton keypad, use a traditional turnkey (two included), or turn the indoor thumbturn. Plus, you can integrate this Zigbee lock into your Zigbee network with the optional Zigbee Network Module.
