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.

  1. Insure that the battery is fully charged.
  2. Turn the ignition switch from the OFF position to the CRANK position attempting to start the vehicle. The vehicle will start and then stall.
  3. Leave the ignition switch in the ON position while observing the security indicator.
  4. When the security indicator turns off, which can take up to 10 minutes (wait at least 10 minutes, turn the ignition switch off. Wait 10 seconds.

The BCM and the PCM will learn the new code on the next start attempt.

HelloCustomer you will need to get the vehicle scanned for the security code, otherwise you will start to have to throw parts at the vehicle.
Customer: replied 8 years ago.

Does the vehicle have to go to the dealer to be scanned or can we take it to a garage with a scanner?


Expert:  Jay replied 8 years ago.
I guess it depends, if the regular garage has a scanner that can scan for the security codes, which I think they will, then that will be fine but the dealer I know will definitely be able to do it.
