Question about Chevrolet Monte Carlo
The SECURITY light is a common problem on GM cars. The key is not just a key, it also communicates with the ignition/lock cylinder, and then to the TDM (theft deterrent module) also known as the computer. When these parts dont communcate properly, the car thinks its being stolen and turns off the starter. The hard part is finding out which part is failing. Mechanics can use this to their advantage and change everything, running up a large bill. I have found that bypassing the system is the most cost effective method and you also never have to worry about the problem EVER again. Ive bypassed dozens of GM vehicles, and never had any issues after that. Here is a link that explains the problem and offers some solutions.

Re: Reset monte carlo anti theift
The reset is correct , key in on position do not try to start if you do you have to start all over . Wait ten minutes , then turn key to off position then repeat 2 more times after third time turn key to off take key out then place key back in ignition then it should start if not there is something else wrong . Also hook a battery charger up to vehicle prior to starting this process so you won't run the battery down .270-556-7357 text with questions
