SOURCE: dont know how to reset or bypass gm theft system car is not starting .It tries and quits.
this is one way to reset it :
first make sure the battery is fully charged , then do the following:
key in the ignition but do not crank the motor, just leave it at the
ignition mode for ten minutes ,then turn it off POSITION for 5 seconds then REPEAT again 2 more times. at the 3 rd time youre gonna notice the ANTI THEFT light on dash to blink. when doing the last step , remove key , inserted again and turn on motor , good luck , AJ

This usually works.Lock the doors with the remote.Press lock twice sounding the alarm.Then press the unlock button twice.Your car should start now.If that doesnt work try this,Lock the car again with the remote once.Go over to the passenger side door and use the key to unlock the door then press in the door unlock all doors.Hopefully by now it worked.Now if none of these work your security probably malfunctioned and theres only two things that will work,One is disconnecting the battery for 5 mins then reconnecting.unlock doors.the start.If that doesnt work you'll have to take it to the dealer to get the security reset or replaced.The steps I have wrot you are the diagnostics to reset it.I hope these work for you and good luck.See ya had have a great day..

Try this I got it from the emission wiz
Put your key in turn it on dont start wait 10 mins remove key wait 10 seconds repeat this a total of 3 times. If that dont work try a different key do the same thing. This relearns your key to the ignition it started with Gm cars and trucks from 1999 to to 2006. It is a big problem but there is no recall that I know of. If that dont work a dealer needs to probably replace and reprogram your ignition switch and keys

I just had this to happen to me - here's what you do - when it will not crank - turn your key over to ACC and let it stay on here for 15 minutes, the THEFT SYSTEM light will stop flashing. Turn your key back to OFF then turn it over as normal when starting and it will start right back up! Found it out from an auto store! One lady paid over $700 and then found this out!!!
