Turn the key into the off position, then turn all the way on with out turning the motor over and let it sit like that for 10 min without touching it. This will reset the anti theft program in the cars computer. After 10 min turn the key to the off position and then try to start the car. It works everytime in this situation. Cars come into my shop all the time for this same issue and other shops stick it to people that are not aware of this common GM defect. I hope this helps and saves you from being ripped of by greedy shops.
