The system MUST be reset by the dealer. They have to download info into the theft system module. No way around it. They use a handheld unit called a Tech 2 which, after you download the vehicles info, has to hooked to another computer mainframe, then info is downloaded to that and then taken back to the car. There is no bypass.

My car wont start ,how do I reset the theft system on a 1999 monte carlo


Is the theft light on the dash lit ? If so turn the key onto the run position till the theft light goes out, about 10min. Turn key off for a few min. then start , hope that helps. If not have to have it checked for codes in the (BCM) body control module or the (PCM) powertrain control module !

Security light came on last night while i was driving now my monte carlo wont start all the lights come on it just wont start


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.
