Replace your old standard deadbolt all while adding another layer of home security to your property with the standalone Yale Assure Lock Touchscreen Deadbolt. This electronic, motorized deadbolt will allow you to easily secure your front door with or without a key because it offers a touch-capacitive 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 keypad, use a traditional turnkey (two included), or turn the indoor thumbturn.
