Abstract
A lock system is provided having a lock housing and a lock barrel, a keeper shoulder, at least one full positioner shoulder, and a positioner shoulder having a U-shaped channel. A lock plug having a keyway and tumblers is received in the barrel for rotation between locked and unlocked positions. The tumblers include a key tumbler, a positioner tumbler and a keeper tumbler. The lock plug is rotatable between a first rotary position and a second rotary position. A control key is received into the keyway to retract the lock tumbler and partially retract the keeper tumbler. Removal of the lock plug from the lock barrel requires rotation of the lock plug from the first rotary position to the second rotary position and the presence of the control key within the lock plug when in the second rotary position.
