Here is a great write-up on the subject. This will get rid of the entire VATS system. It was the only thing that saved my 94 Park Avenue. http://newrockies.com/vatsbypass

I had the problem and when i took it in they wanted a ridiculous amount of money to fix it.. It is the security system failing. i did a ton of research and found a module that u can install yourself that will bypass it and allow the car to start every time.. i did mine like 5 years ago and i havent had an issue since.. you car is on the list year make and model for having this problem i guess its really common in GM vehicles .. Check out this website they have great customer service and if for some reason it does not work they will refund you 100% of your money!! I hope this helps ya i know how frustrating it is.

Have an Oldsmobile 1997 Achieva security light stays on and won't everyhing but still won't start , would like to know would the Pro VATS Full Bypass work on it.


If the security light is on, then you have a failed antitheft system. This light is only for this. If you bypass the system, your car will work perfectly again.

Car was rinning perfect. One day it would not start. there was nothing, no clicking ,bell and guages were working. Jump start was nothing. Installed a new battery there was nothing. Went bact back 2 hours...


It sounds like you have an issue with your PassLock security system. I had the same with my 2002 Impala. Key turns OK, but won't start, won't crank. Wait 20-30 minutes, and car starts normally. There is usually a clue from the Battery and Security lights.
The problem starting to happen once a month, and eventually 1-2 times a week.
There are several write-ups on this problem for several GM cars for 2000-2006(?). Search this website, and search the web.
The official solution is to replace the ignition switch. The best solution is to bypass the Pass Lock system. I went ahead and did a full bypass, which involves cutting wires and adding resistors to the ignition circuit. I have not had a problem since.

1997 oldsmobile 88 won't start the security light


Im guessing you tried to bypass the key in the ignition/steering column. This is ok unless the actual problem was in the TDM (theft deterrent module) In this case, the 2 wire bypass does nothing. There is another way to bypass this. Check out this link for tons of info and some DO IT YOURSELF options. Ive done several key bypasses and tons of full bypasses. They both work well, it just depends on what part is failing. I think you need the full bypass to eliminate that TDM.

I have a 2003 alero olds that starts and runs for awhile then engine stops i have changed 3 fuel pumps still same problem and i can try the next day it may run for awhile then stops again sometime i can...


It's that infamous "chip" in the key that becomes a nightmare to many. The security light may or may not start flashing. Sometimes it stays on steady. Gradually the car begins not cranking anymore or if it cranks it will start and die in a second. Randomly it will do this more and more often until it won't start anymore. VATS, PASSkey and Passlock immobilizer systems are killing cars all over North America, they have a short lifespan and are certainly more effective against owners than thieves. Here is how you save your car
QUICK FIX TRICKS
1st trick, Try a spare key that is newer or used less. The pins wear down with use and so do the keys causing the security to fail.
2nd 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. If its shutting down while running, I'm sorry I have no quick fix...
CHEAP FIX: Bypass the chip in your key. This is temporary, but effective until the TDM (theft deterrent module) in the dash poops out. Then you're kinda screwed. I was told that these types of key security systems have a 6-10 year life span. Sucks for us. This link explains the "Key Issue" pretty well.
----- http://vats.likeabigdog.com/

If you're gonna tear your car apart anyway, just do this next fix and bypass it all together. Its more money, less work, and a PERMANENT fix. Up to you tho.

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. It took longer to find the "Theft Deterrant Module" than it did to fix the problem. They sell a unit for 200 bucks to totally bypass this system FOREVER. life time-money back and all that. Finally did this in my car. Well worth the 200 if you've looked into getting this replaced... It can cost anywhere from 600-1000 bucks. If you do buy this, please purchase it thru this link.
----- http://newrockies.ca?ap_id=judd0081 ----- With this fix, you can take that whole Vats, passlock, passkey system out of your car all together. Good info on both sites.

It works for:
Any GM or Isuzu Vehicle with VATS or PASSKey or PASSLock security systems.
If your car has the chip in the key or in the lock cylinder, then you can save it with this Full Bypass.

Ignition keeps going into security car starts then stalls and security idiot light flashes


ignition switch problems on these cars are notorious, you can bypass the anti-theft module by placing a resistor inline so that the module 'thinks' the correct key is not an attempt to steal the car. the anti theft is located behind the glovebox and the resistor costs 15 cents at radio shack, not as hard to do as it sounds and it fixes it for good.

I have a 96 Olds Cutlass Supreme that intermittently won't start


If the lights on the dash all come on but the engine wont turn over it could be a problem with the VAT security system. Your key has a little chip on it between the teeth and the handle. This is a common problem with GMs', often just replacing the key is necessary but sometimes the VAT module needs to be replaced.
