You have a problem with the Passlock system. I'm giving you the relearn procedure. This may or may not work. If it doesn't work, that means there is a failure elsewhere in the circuit and it will require a Tech2 scan tool to be able to diagnose it.
PASSLOCK 10 MINUTE RELEARN
AUTO LEARN
Time required, approximately 10 minutes:
1. Insure that the battery is fully charged.
2. Use the scan tool in order to clear the DTCs.
3. Turn the ignition switch from the OFF position to the CRANK position attempting to start the vehicle. The vehicle will start and then stall.
4. Leave the ignition switch in the ON position while observing the security indicator.
5. When the security indicator turns off, which can take up to 10 minutes, turn the ignition switch off. Wait 10 seconds.
6. The BCM and the PCM will learn the new code on the next start attempt.
