HelloCustomer Here is the procedure for resetting the security system on your car. Please reply if you have any questions:
Time required, approximately 10 minutes.
The BCM and the PCM will learn the new code on the next start attempt.
We have tried this about 5 times and the security llight will not go out. We also tried unhooking the battery and hooking it back up and tried the ignition thing again and the security light still will not go out..........is there anything else we can try.
Thanks for your help :)
Does the vehicle have to go to the dealer to be scanned or can we take it to a garage with a scanner?
