    do u have a name brand for the electrical cleaner so i can know what im looking for? what does the resistor look like and where it is located exactly? I went to the mechanic and he did disconnect the security alarm sytem with the car starter. so i have to manually open the car door. when I went back and told him the security light continued come on he did say that is part of the car and cant be disconnected.

I should have asked a few questions, like did the car start and run with the light on. If it did then the resistor probably isn't bad. I assumed the car wasn't starting so that's my fault. It could be the alarm module itself has gone bad(but doubt the car would start). So more likely one of the sensors that the alarm uses to protect your car, like the door sensor or the trunk sensor or even just a ground wire to one of them or alarm module itself and the cars computer should tell you if it's one of those. You can take your car to Auto Zone or Advantage Auto and ask them to check the computer codes for free, Advantage gives you more and better info. You can buy any brand of electronic cleaner from places like best buy, circuit city or even radio shack. Just ask a clerk for assistance and tell them you just want the spray that you can use on printed circuit boards or elctronic parts. The resistor is located on the part of the key that goes in the ignitionif you still want to try it but I would have codes checked first. It's a little bump right by where you would hold the key but close to where the teeth are on the key. If it's the alarm module then I'll have to do some research to find it's location for your year of Bonneville. I will check back to see what you found out. In the middle of moving so not so quick on replies and sorry for that.

Does it have a factory alarm? Do you have a second set of keys, if so try the extra key first. Your keys should have come with a extra little chip not in the key that tells what resistor they need to replace the key. Your key has a resistor in it that allows the car to start so it could just be the key. If it's not the key that needs replaced then the alarm module under the dash is bad. Unless the resistor in the key did in fact go bad which I have never heard of happening, then that would be a cheap fix. If it doesn't work with the other key then the security module under the dash is bad but can be bypassed but you won't have an alarm. It's really a very easy fix. I've heard of the ignition and/or key getting dirty after prolonged use and have been told that you can clean the key by rubbing and eraser over the resistor a few times and then spraying an electronic cleaner in the ignition and inserting the key in and out while it's still wet. Haven't heard of that happening much at all though. Battery has to be disconnected to do that though or could cause more problems. Electronic cleaner dries really fast and wouldn't harm anything. If you want to spend $10 bucks to give that a try it might be worth a shot. The right way to fix it is the replacing the key or alarm module if it's not just dirt film. Theres a panel under the stearing column that you remove but I will have to do some checking to tell you where the module box is located but I doubt you want to do this yourself. I think the dealership has to match the key to the module unless you have the chip? Not sure if they can just use the bad key or not. Dealerships charge between $60 and $100 just to pull the vehicle in the door so pray you have that little chip or that they can just use the key. But CALL a dealership first and ask if they can use a bad key without having the little I.D. chip. I guess to answer your question YES it could very well be the key itself. Hope this helps some!

What you need to do there is to turn the ignition switch on and off three times, leaving it on the third time. Leave it on for about fifteen or twenty minutes and the light should become steady. then you can start the engine. (I usually put a jumper battery on it to make sure it does not knock down the battery too far) If that fails to work, then the problem likely is in the switch or the security module.

This is most likely a break down in the security anti theft aspect of the vehicle. When the computer can't read the keys transponder or chip properly, it goes into anti theft mode and turns off the starter. Check out this link for info and answers.

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!

My security system in my 1992 pontiac bonneville is blinking and my car wont start what can i do, i have a reset key where do i put it


Sounds like your theft modulator has gone bad. The same thing happened on my 94 Deville. Try Disconnecting the positive cable from your battery for 10 minutes to reset the system. If That doesn't work look into replacing the theft modulator.
