Try this Reset / Relearn for the Security System: Be sure Battery is fully charged & connected With a master passkey III key (Black), turn ON the ignition, with the engine OFF. Observe the Security telltale, after approximately 10 minutes the telltale will turn off. Turn OFF the ignition, and wait 5 seconds . Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes . IMPORTANT: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. With a master passkey III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password You will have to do this a total of 3 times.
