1996 cavalier theft system light stays on and car doesn't start?

I JUST wrote in here 15 minutes ago pleading for someone to answer this because I had the EXACT same problem-just replaced the cluster, tried ressetting the codes by pulling off the positive cable, and my car would not run...After reading and searching for clues and answers on this website, I found that someones answer-try to lock the car and unlock the drivers side door WITH the key- the anti theft ligh stopped flashing and the car started right up and ran fine! I hope ur as fortuante as I was cuz, man that was frustrating... Thanks a million WikiAnswers (and those who helped answer)!
