The VATS (Vehicle Anti-Theft System) module, often referred to as BCM (Body Control Module), is designed to enhance vehicle security by preventing unauthorized engine starts. It utilizes a resistor embedded in the ignition key to communicate with the vehicle's electronic systems, ensuring that only the correct key can start the engine. If an incorrect key is detected, the BCM disables the fuel delivery or ignition system, effectively immobilizing the vehicle. This system helps reduce vehicle theft and enhances overall safety.

Can a 1998 Firebird body control module be reprogrammed?

When you replace the body control module with a used BCM you will need to know the VATS code for the key. It may be possible to get that code if you have the VIN # from the donor car. A new key then has to be made to match the donor BCM. At a cost of around $30 for the key it may be worth it. Otherwise you will have to buy a new BCM at around $300. Good luck!

How do disable or bypass the anti-theft system in your 89 Firebird - It randomly won't start for bc of this?

Disabling the VATS system is not the right answer. Bypassing the VATS system on a '89 Pontiac Trams Am requires grounding the crank/start wire on the VATS box (located behind the dash, behind the console) and purchasing a bypass module, which is used in order to allow the fuel injectors to operate. Baker Electronix offers a DFVATS module for this purpose.
