Abstract:

A secure lock box system for secure storage and retrieval of a stored key includes a key fob device that requests access to a lock box by inductive or optical communication. The individual key fob is authorized for access to the lock box by prior radio communication with a key fob controller that validates the key fob. A lock box controller in combination with applied pressure to a latch hook conserves power and controls access to the key by operation of a low power solenoid and a latch mechanism. Tampering with the lock box is detected by a piezo film motion sensor that provides a signal to a microprocessor, which is awakened from a low power condition by the signal. Upon access grant or an unauthorized attempt at access to the lock box, a message is transmitted from the lock box to an annunciator. The annunciator relays a message concerning the attempted access to a server where a log is created and stored. The server and key fob controller maintain data concerning one or more key fob devices and provide separate authentication data for each. The annunciator warns of any unauthorized access attempt or tampering with the lock box.
