Abstract
A multifunction lock unit is disclosed. The unit is a single, contained unit that includes a base box near an overhead door and a deadbolt in the base box that protrudes into a hole in the overhead door to lock the overhead door. The deadbolt is extendable into the hole and retractable out of the hole. The unit also includes an actuator in the base box coupled to the deadbolt and configured to extend and retract the deadbolt. There is a wireless communication module that can receive a signal from a control unit to extend or retract the deadbolt via the actuator, and send a signal to the motor unit to raise or lower the overhead door. The unit also has a light on the base box for displaying at least two colors of light to show a status of the unit.
