Ok, you need to do the relearn procedure

30minute GM relearn procedure:

1-TurnON the ignition,with the engine OFF.

2-Attemptto start the engine,then release the key to ON (vehicle will not start).

3-Observe the SECURITY telltale(this is the security light), after approximately 10minutes the telltale will turn OFF.

4-Turn OFF the ignition, and wait 5 seconds .

5-Repeat steps 1through 4 two more times for a total of 3 cycles/30 minutes(the vehicle is now ready to relearn the Passlock(TM) Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK). IMPORTANT: The vehicle learns the Passlock(TM)Sensor Data Code and/or password ***** the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

6-Start the engine(the vehicle has now learned the Passlock(TM) Sensor Data Code and/or password).
