ABSTRACT:
A high security lock has a protective shell with a hole in it. A lock body is held within the shell by an end plate having a loop around the body. A plug having an end flange is rotatable in the body and is pierced by a keyway defining an edge notch in the end flange. A guard plate is disposed in the hole and over the end of the plug and is arranged to rotate in the shell with the plug by a tab disposed in the edge notch so that a restricted opening through the guard plate is kept in alignment with the keyway.
