Abstract: A key-actuated cam lock includes a lock housing having a first end and a second end. The lock housing includes a bore that extends from the first end to the second end to house a plug body. The plug body includes a first end, a second end, and a plurality of spring-biased tumblers that can be engaged with a key to open and close the lock. The first end of the lock housing includes a circumferential inner rim that is sized to house the first end of the plug body. A closure plate that includes a key opening partially covers the first end of the plug body. A generally cylindrical metal cap is attached to the first end of the lock housing to securely cover the first end of the~lock housing, the first end of the plug body and portions of the closure plate. The first end of the lock housing, the closure plate and the metal cap collectively define a lock face.
