It depends on which anti-theft system yours has . VATS , PASSKEY 1,2etc... your vehicle is not new enough to have PASSKEY 3 . There are videos on you tube on how to by pass it . You need to find out what resistance yours has , go to radio shack or some other electronic store an by that size resistor . Then you need to find the right wires under the dash coming from the steering column ,if your ignition switch is in the column .Then solder the resistor to the two wires . Does you ignition key have the pellet on the side ? The two wires your looking for are white inside a yellow or orange sheath , plastic shield .

If the lights on the dash all come on but the engine wont turn over it could be a problem with the VAT security system. Your key has a little chip on it between the teeth and the handle. This is a common problem with GMs', often just replacing the key is necessary but sometimes the VAT module needs to be replaced.

problem could be the ignition key and switch or the theft deterrent module relay is bad or the theft deterrent module is faulty.this is a dealership fix.

Check the wire from the module to the crank sensor. They go bad. Usually from oil leaks. Is it saturated with oil where it goes under the engine? Also check for power and ground on the two wire plug on the drivers side of the module. It isn't the ecm or anything with it. The ignition system on the 3.1 will work with the ecm unplugged. The ignition system is a stand alone system. It sends signals to the ecm for the fuel injection.
