ABSTRACT:
A rekeyable cam lock has a plug rotatably received in a cylinder. The plug has a keyway and pin tumblers and is provided with a circumferential groove rearward of the pin tumbler. The cylinder has a bore to receive the plug and a pair of transverse holes to receive a U-shaped clip in registration with the plug groove. The clip engages the groove, permitting rotation of the plug but preventing its removal from the cylinder. When the clip is removed from the holes, the plug is forwardly removable from the cylinder to facilitate rekeying of the lock.
