I doubt it has anything to do with the key. I don't know allot about the factory security systems in these cars but I don't think there was any chip teck in the keys so that means as long as they allow you to turn the ignition switch then it's not the problem. Out of curiousity where are you located? Also, is there any way we could talk on the phone? It would speed up the exchange of info. Let me know. I'm in Florida with nothing to do for a few hours.
