1. In an electronic lock system for operating an electro-mechanical lock box having an input port for an electronic key with a power source, the addition of a radio data link to relay information to a nearby receiver with a connection to an autodialer modem capable of connecting to a central site computer comprising:(a) a housing that adapts to the lock box and accepts the electronic key while maintaining electrical contact between the lock box and the key; (b) means for attaching said housing to the lock box, with said housing containing a miniature radio transmitter with antenna, which is powered from the power source via said electronic contact between the lock box and the electronic key; (c) circuitry within the housing to convert the electrical pulses from the electrical contact with the lock box to the electronic key in a form that can be electrically applied to modulate the radio transmitter in the housing; (d) a receiver located in a nearby location to the lock box which is tuned to the frequency of the radio of the radio transmitter in the housing; (e) an auto-telephone dialer connected to the receiver to call a central site computer to retransmit the lock box data to the central site computer for final processing; (f) a central site computer to service a plurality of lock boxes, interpret the data and process the data into meaningful reports.
