Try it again, Important: Do not remove the key from the ignition during this procedure. If the key is removed, the procedure will have to be performed from the beginning.

Turn ON the ignition, with the engine OFF.
Attempt to start the engine, then release the key to ON. The vehicle will not start.
Observe the SECURITY telltale. After approximately 10 minutes, the telltale will turn OFF.
Turn OFF the ignition, and wait 5 seconds.
Repeat steps 1-4 two more times for a total of 3 cycles/30 minutes. The vehicle is now ready to relearn the Passlock√ Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.
Important: The vehicle learns the Passlock√ Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

Start the engine. The vehicle has now learned the Passlock√ Sensor Data Code and/or password.
With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.
If this does not work, only other fix is to have it reprogrammed with a tech 2. If not you might have done something wrong or forgot to plug something in, the relearn usually works, follow this info and post back with what you find.
Was this
