How do I bypass 1992-94 buick park avenue security system?

It is very difficult to bypass because the anti theft system and immobilizer is there to stop exactly what you are trying to do.

It is better to fix it rather than finding a way to defeat it. Have a read.

You just fit a Bypass Pulley. This takes the place of the AC compressor, the belt and routing stay the same.

i think i know the issue.. your security system is failing. it happen to my car a few years ago.. i found a module that you can install yourself and it will bypass all of it and your car will start and run every time. you should check it out . if for some reason it doesnt work they will refund you money .. hope this helps

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.

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.

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.

----- 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

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.

You will find a great write up on this website:http://newrockies.ca . That was the only way I saved my 94 Park Avenue that has the exact same system.

I've got my own one stuck for weeks and this was the only thing that brought it to life again : http://newrockies.ca/vatsbypass

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.
