Car starts and then shuts off. The problem is the is the security system for the ignition system. Is there a way to bypass the security system?

Starts everytime and shuts right down? Usually an indication of the security system. I had to bypass a 98 Malibu because of this. A lot of those era Chevys had problems. Check the videos on it. I don't know exactly what one your car has. 2005 impala security bypass YouTube

depends on design on unit, on most you can simply disconnect system power and youre good to go. other in line systems require un installing the unit. either way sounds like the system is causing more problems than its solving. i would suggest removing it entirely

The security icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

It is common practice to "bypass" only a section of the VATS system and believe you have gotten it all. Go to this link for info and the better way to bypass the system.

The problem might be your Vats security system. This causes the car to either "not start" or "shut down" while running, or start for 5 seconds and then die. (depending on the system) If the security light flashes, i guarantee that this is what the problem is. 1st trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my regal for more than a year.

Cheap fix: Bypass the chip in your key. Temporary, but effective.

Never worry again fix: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it out, and throw it away. I just did this in my Regal. Took about an hour. Took longer to find the thing than it did to fix the problem. For a list of cars effected by this problem. See the NEWROCKIES link on the right side of their page.........

I think it is related to the GM security system. If your ignition key has the little chip or resistor in it, then this could be the problem. The system is unreliable and stops working without any warning.When it malfunctions, it shuts down the starter. If that is in fact what has happened, the dealership will want $1000 to fix it, unless, of course you still have warranty. The following website has a bypass system that works. Visit the website and read about the problems with the security system and the bypass: http://newrockies.ca/vatsbypass.

You need to either replace the ignition lock cylinder or bypass the security system. If you need help with either one, repost.

Yes, I can tell you how to bypass the security system. First does the ignition key have a resistor pellet in it?
