ABSTRACT:
A method and tool is provided for deciphering electronic codes and recreating lost or missing vehicle ignition keys for vehicle ignition systems in which an ignition key is employed which has a diode containing one of a plurality of possible electronic codes which must be sensed to operate the vehicle. Once the mechanical key code is determined for the cuts on the key by removal of the ignition lock portion, a key blank without cuts but containing a diode having one of the possible electronic codes is inserted into the lock portion, and a tool is inserted into the steering column which has been opened by the removal of the lock portion to move the rack gear to operate the ignition switching assembly to the start position. If the diode code on the key blank is the correct code, the engine will start. If it is the incorrect code, a different key blank containing a diode having another one of the possible codes is inserted in the lock portion, and the foregoing procedure is repeated until the engine starts.
