On mine I bypassed it with this solution after it was locked down for weeks: . This one will bypass the entire system and not only the key and lock cylinder. I wanted to kick the whole system out of my car and never hear about it anymore.

The security system prevents the engine from cranking and the injectors from getting power. You can bypass the system but it is not an easy job.

My car starts and runs for 5 seconds. It had a new key cut and computer replaced prior to me purchasing it. I have tried to reprogram the system but the security light wont go out after leaving the ke

This is definitely the security system. It now doesn't match your computer. It must be bypassed or replaced. Best way for the money is to bypass. Here is a link to help you with this problem.

What is causing my 91 park avenue doesn't always start. after it sits for awhile it will start. what is causeing this

Could be neutral safety switch. Try starting in neutral instead of park. When a starter begins to fail, it will get "tight spots" where it gets stuck. How did you fix the security? Skirt off the time people only bypass the ignition and key with a resister, this leaves part of the security system still in the vehicle, causing the same "no start" situation. Here is a link on that.

My 1994 buick park avenue will just turn off randomly while im driving and all i have to do is stop put it in park and turn off the key then start it like normal and then i can drive. sometimes it does...

The problem is your Vats security system. This causes the car to either "not start" or "shut down" while running. (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.

Cheap fix:
----- Bypassing the key

Never worry again fix:
----- With this fix, you can take that whole Vats, passlock, passkey **** system out of your car all together. Good info on both sites. I just did the NEWROCKIES bypass on my regal. Worth the 200 bucks, did it myself in under and hour

How do you disconnect the security System in a 1992 Buick Park Avenue

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 exact 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 and is still working perfectly after 5 years. Don't go to the dealer!

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?

It is ALOT cheaper to get the security fault repaired then to try to bypass the system.It is a veryyyy time consuming task and doesn't always work.

Don't know if your car has a security system, but it may be your key. There is a very tiny electronic piece on the key of my Buick Park Avenue 1995. If damaged, it may activate/desactivate the security system randomly.
Hope this helped you.
