Abstract: A cam lock for cabinets, drawers, drug cabinets, credenzas, sliding doors, lockers, mail boxes and other door type applications is compact in size, fits an existing cam lock opening and provides electronic access via a keypad or other electronic access. Using batteries, such as AAA size batteries or smaller, the lock has electronics that release a lock turn knob or handle when the correct code is entered. Preferably a set of electronic contacts is included at an accessible position on the lock housing to allow both master access and power jumping with a common manager's implement, for situations of lost codes and/or battery failure. In a particular embodiment the lock is long, narrow and low in profile so as to fit on the margin of a steel or wood file cabinet, compatible with the cam lock opening already provided.

Abstract: An electronic cam lock accessible either by PIN code or wirelessly transmitted code from a user's credential has a compact electronics housing that fits neatly and unobtrusively in office furniture, including metal or wood file cabinets. The housing has a rear-extending driver, which may be within a cylinder, preferably positioned where the driver of a cam lock of conventional keyed configuration would be located. One form of the lock is front-recess mounted. In another form the housing is inside-mounted, fitted within the usually one-inch top rail or vertical side rail of a file cabinet, with the electronic access terminal and a rotatable knob exposed for the user. The locks can be connected in a wired or wireless network for controlling access by time or by personnel, or for auditing entries.

Abstract: A combination lock, such as a dial combination cam lock, has a mechanical key override, the mechanical key extending through the manual knob of the cam lock. For a lost mechanical key situation, or to change the mechanical key, a special key or device can be inserted to enable the knob and key core or plug to be rotated to a further position not normally available. In this position the key, knob and core can be removed, then replaced with a different key and core, preferably using the same knob.
