Abstract: A padlock includes a body with a primary channel that rotatably receives a sleeved cam. The sleeved cam contains a vending style lock with a deployable lug. The lug aligns with a window in the sleeve of the sleeved cam and extends through the window into a lug compartment in the body when locked. The cam of the sleeved cam moves locking members (e.g., balls that mate with hemispherical notches in a shackle), when the sleeved cam rotates between locked and unlocked positions. The padlock may be rekeyed by replacing the lock plug.
