Abstract: Lock systems for selectively securing and accessing an enclosure include a housing having a movable locking member disposed therein, with the housing being suitable for installation on the enclosure interior, for example proximate a door. A drive device disposed in the housing is operable to move the locking member between locked and unlocked positions, to correspondingly engage and disengage the door. A receiver responsive to signals transmitted by one or more remote control units selectively operates the drive device. Some embodiments include a wireless remote control unit as well as a wired remote control unit, and may couple with an external power supply to power various components of the lock system.
