    Never had a problem with the security system until we changed the alternator now the damn light comes on and we can't start the car. Isn't there a way to bypass the security system?

    Incidentally, what was the initial problem?Did you try to start the car one day as you might normally have, and weren't able? Did you have a spare key made and now you can't start the vehicle? Please elaborate, because the VATS is tied into the whole vehicle through the ECU.

How do i get the proper security code for my 95 pontiac bonneville sse, so i can replace the lost ignition key?


There are 15 possible codes. They are listed on this site. It is possible to bypass that part of the system and then use a regular key. With a little effort and know how, you could fix this rather cheaply. Alot of info on this site. http://vatspasslockpasskeysecurityhelp.yolasite.com/

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.........

Security light is flashing and the car wont start 1997 pontiac bonneville sse


The security system (VATS/Passkey) installed on these GM cars is anti-owner more than an anti-theft. There are 3 parts involved: 1) The chip-key 2) The lock cylinder 3) The TDM (aka the brain of the system) if any of these parts fails or is even slightly malfunctioning, the car stays stuck where you are and you only get a dealer asking you about 1,000$ to fix it. And all the 3 parts have a quite short lifespan. Way too many people got in this situation (including myself). I don't recommend any partial solution or any used parts as it would happen again way too soon to be acceptable and if it happens 100 miles from home (like it happened to me....) it's a big burden. I finally made it to save my beloved 94 Park Avenue (with the same system that is installed in your car) with a solution that I found on the internet and that bypasses the entire factory security system, all 3 pieces altogether and you can even remove the TDM at the end and use 99c keys without chip. The product I used is at http://newrockies.com and is still working perfectly after 5 years. Don't go to the dealer!

You can easily bypass the entire VATS system. There is a clear write-up here on this website:http://newrockies.ca. This was the only thing that saved my 94 Park Avenue with the same security system.
