Permanently eliminate lock picking and secure your door with the Yale Assure Lock SL Key-Free Deadbolt, Standalone (No Smart Module). This keyless motorized deadbolt replaces your standard turnkey lock with a touchscreen keypad which uses a 4-8 digit code to unlock the door from the outside and a standard indoor thumbturn on the inside. The keypad features one-touch tap locking and 30sec auto locking, which can give you peace of mind as you leave. As a no-cylinder "key-free" model, the deadbolt prevents lock picking or bumping.
