Hi Pete, actually the answer is both. The original key has to go in the ring where the chip is. and the new key and cylinder have no chip.
My son bought it on ebay and installed it. It does work to start the car. it just won't stay running. It was for either 9-3 or 9-5.
So bring it to a dealer is the best advice you can give me?
I don't think anyone can help me. I guess I will have to take it to a dealer. I hope it won't cost too much. Thanks pete for all your help. Bev
I really have no idea how to rate your expertise, I'm not sure if I just dont like your answer as I can't afford to have a dealer help. I will any way yoiu think is best. Just let me know. Bev
