The Baldwin Square Single Cylinder Deadbolt is keyed only on the exterior with an associated thumb turn on the inside that can quickly and easily lock or unlock the mechanism. Single cylinder locks are most commonly used to secure entrances in residential locations due to safety and ease of use. Patented side locking bar technology offers improved security by protecting against lock bumping, an attack technique used to defeat conventional pin and tumbler locks.

The Baldwin Square Single Cylinder Deadbolt features SmartKey technology. This re-key technology allows you to re-key your lock in seconds. It also features stainless steel racks, pins, and side locking bar for increased strength and security. Fully reversible to fit both right handed and left handed doors.
