I am sorry that you have not been helped yet. I just came online and saw your question
You need to put a charger on the battery and charge overnight. If security message still appearing, then you need to do the relearn procedure
30 minute GM relearn procedure:
1-Turn ON the ignition, with the engine OFF. 2-Attempt to 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 10 minutes the telltale will turn OFF. 4-Turn OFF the ignition, and wait 5 seconds . 5-Repeat steps 1 through 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).
