Question

Answer
hi john....if car has security system disable it...you will need to know if it is passlock 1 or 2 . i have never run into a factory installed system that won't let the car run...if yours is the system that has the key chip check to be sure that the chip is not damaged. you can get new key from a dealer...hope this helps
