Right Handle Mechanical Door Lock Keyless Digital Code Keyless Entry Keypad Password Security Combination for Wood Metal Plastic Door Stainless Steel 304 (Not Deadbolt)

We chose this door knob over others because of its lack of a battery. It was easy to install and works exactly how we had hoped it would. We are thinking of getting a second one for another door. I highly recommend it to others.

Nice but needs a light or light up keys.

Works great on our office doors.. no battery operation, once we got the hang of how they worked all was good
