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. KeyMark is best known for its restrictive keyway, marketed as the "Security Leg"™.

Principles of operation

The KeyMark is a standard pin-tumbler lock that uses six pin stacks. The key raises all pin pairs to the correct height and the plug can be rotated. KeyMark models that use interchangeable cores have a dual shear line mechanism similar to those found in BEST locks. No security pins are used in the Keymark.
