leave your key in on postion do not try to restart it, don't even touch it
your theft light should be either blinking or on...
you can either crawl out of your car "not doing anything that would cause your interior light or any other battery functions" or sit and wait like... 15-20 minutes until the theft light goes out.. then turn the key off and try to start again vaoila...

he is decribing the key learn procedure.. and it doesnt work if your car is in a no-start condition. if you got a new ignition installed, your passlock resistance might be different than what your bcm wants. i advise you to take your car to the dealer to have them re-program the key

now i have installed a new steering column because that is what GM recommends and a new computer and nothing is fixed. they did reset my code for a bad fan switch though so not a total loss. lol now they are wanting to have it towed like 2hours from here to hook it to a machine that bypasses the theft system but i have already spent too much money on this car. any suggestions?
