My car doesn't start I by-passed the VATS system but it still wont start. I was told I need to replace the Theft Deterrent Module in order to start my car. But I don't know where it's located. Also does it need to be reprogrammed after I replace it?

I am still having trouble with the same car 97 Pontiac Bonneville. I need to remove the BCM ( Body Control Module). I have located it, but I am having trouble removing it in order to get the part number to get the replacement. Please tell me how to remove it without causing any damage to the BCM? Thanks

I finally was able to remove the BCM it was actually very simple! Can you tell me where the anti-theft module is located? Or the TCM (theft control module? Even though I had a professional to bypass the VATS system is it possible he got it wrong,because my security light still flashes.And everything that I have read tells me that my problem is dealing with security system and having the right OHM . Please don't miss understand me I really appreciate all of your assistance
