The KeyMark is a pin-tumbler lock made by Medeco. The KeyMark is designed for installations where key control is more imporant than resistance to physical attacks, but it does offer basic defenses against picking and destructive entry.[1] KeyMark is best known for its restrictive keyway, marketed as the "Security Leg"™.
Principles of operation
- See also: Pin tumbler (Principles of Operation)
