Electronic security system for controlling access to an automotive vehicle. The security system includes a computer system having a processor subsystem connected to selectively enable or disable an ignition system of the automobile and a memory subsystem having ignition, valet and reprogramming key codes and first, second and third validation codes stored therein. To control access to the vehicle, an encoded signal containing a device code and an authorization code is propagated to the processor subsystem where the codes are compared to the ignition key, valet key, reprogramming key and validation codes. If the propagated device and authorization codes match the ignition key and first validation codes, the processor subsystem enables the ignition system for a pre-selected time period. If the propagated device and authorization codes match the valet key and second validation codes, the processor subsystem enables the ignition system. Finally, if the propagated device and authorization codes match the reprogramming key and third validation codes, the processor subsystem reprograms the memory subsystem to modify the key and/or validation codes. |
