2002 Firebird won't start sometimes and security light comes on. This is becoming more frequent.?
I turn the key, and the engine does not attempt to crank over. The security light comes on. After waiting for 3-4 minutes, the security light shuts off and I can try to start it again. It used to be a infrequent problem, and would start after the light went off the first time, but now sometimes I am trying for a half hour to get it to start. I have tried unlocking my doors with my key instead of my remote, and I have switched to my second key, but nothing has helped, as the problem is just getting worse. I have found no combination of any sort of having the doors locked or unlocked, open or closed, it will start at random. Could it possibly be the ignition switch that needs changed?

Apparently your 2002 Firebird uses GM's original Passkey Passive Anti-Theft System. There is a resistor in the key that mates with contacts on the ignition housing. That is normally the trouble spot - those contacts. You can try cleaning the contacts with a Q-tip and alcohol (may as well clean the keys, too) but if that doesn't do it you will need a new ignition cylinder. The only good news: keys are not expensive, and the ignition cylinder itself are not shockingly expensive.
