Abstract: An alarm clock housing with lockable keypad enclosure that includes a time/alarm entry keypad. The lockable keypad enclosure is lockable with an enclosure cover combination locking mechanism that includes a receiving tube cavity formed into the molded alarm clock housing member, a locking solenoid with a normally extended retractable locking bolt, three rotary combination wheels each having a shaft receiving aperture and a shaft conductor contact, a split conductor wheel shaft including three nonconducting gaps along the length thereof, and left and right rotary shaft contacts each with a conducting lead wire. The normally extended retractable locking bolt is sized and positioned to be extendable into the locking bolt receiving tube when the pivoting enclosure cover is pivoted into the closed position.
