Image Number 5 for United States Patent #5373282.
A security key control information system and method for vehicle dealerships and the like is provided. A key storage device A mounted to each vehicle window has a compartment for storing access keys B to the respective vehicles and contains a sensing device H which produces a signal indicating whether an event related to that vehicle is routine or hostile. A second device may be permanently attached to the vehicle for regularly transmitting identifying information as to that vehicle. Both devices report the information by radio through an intermediate transmitter network to a computer D inside the dealership which records the information along with the time of the event. The information is stored for subsequent retrieval for the purpose of generating reports useful to the dealership management. If an event is hostile, appropriate action may be taken including suitable signaling.
