Wow, that is unusual. But, considering how complex these systems are today, nothing really surprises me. You would think that it should at least show something in history in the way of a code, but anything is possible, I guess. On the older pass lock systems we used to bypass the ignition lock cylinder and the password XXXXX soldering a resistor into the line so it would always start. I have not tried it myself and I am not sure which of the other two wires are involved, but I am going to pass a note on to you that I received from another technician who is very knowledgeable and I trust what he says completely. It would just be a matter of removing the covers to get to the harness and then trying one of the other 2 wires and if it doesn't work, that would only leave one other wire as a possible. I will post it below, just in case your interested in giving it a try. I am going to try it the very next chance I get, but so far this week have not had an opportunity. If you do, let me know the results. Thanks
You wire a 2200 ohm resistor across the 5 volt reference and return on the sensor wires-there are 3 wires-power ground and return-the yellow is the return and that is the wire you jumper to the 5 volt reference.Then relearn the theft deterrent using the 30 minute procedure of going to start-leaving the key on until the security light stops flashing-turn the key off for 20 seconds and repeating the procedure until it starts,
