Now the car is at home and won't start

Question: My girlfriend has a 1999 Pontiac Grand-am, the upper radiator hose went on it. We had it towed to a garage and repaired. Now the car is at home and won''t start. How do I reset the security system, or disable it. Already Tried: Locking and unlocking the doors! Answer: Disconnect the battery. Insert the correct ignition key and turn the key to the "ON" position (not start). Then with the key left in the "ON" position, connect the battery. It is now reset. If you turn the key to start and nothing happens, it is not from the security system. The security system just turns off the fuel, so the engine would still crank over. If it is not cranking over. You will need to make sure you have a good battery (out of a car that does start) Just because the radio and lights work, does not mean it has enough juice to turn over the starter.
