ABSTRACT:
A lock has a drive member which is moved to actuate the lock. A plurality of elongate members are connected to the drive member, one end of each elongate member being inserted in a respective spring-biased plunger. A first contoured element locates the plungers in position. An appropriate key must be inserted with a contoured surface in contact with a second set of plungers to align passages in the second set of plungers with the ends of the elongate members to enable the elongate members to move, thus permitting the lock to be opened.
