Abstract

A cylinder lock includes tumbler pin assemblies and a secondary locking element associated with at least one of the pin assemblies. The secondary locking element is biased outwardly to engage a locking feature formed in the bore of the housing to prevent the plug from rotating within the bore. A portion of the associated primary pin assembly extends through the secondary locking element and into the keyway and is movable independently of the secondary locking element. The secondary locking element includes at least one control feature that is directly or indirectly engaged by a key inserted into the keyway to cause the secondary locking element to move inwardly toward the plug so that the secondary locking element disengages from the locking feature or to permit the secondary locking element to be moved inwardly toward the plug so that the secondary locking element can disengage from the locking feature.
