Default security system issue

My bonney is playing games with me! I've recently noticed that my security set up on my car doesn't work any more, I think it started about 2 months ago when I started my car and the security light came on and stayed on I tried restarting it and the light still stayed on, the next day the light was back off. I noticed the alarm wasn't working when I left my keys inside and i reached in through the window to unlock it, normally my alarm should have sounded but the light didn't even stay on? Any ideas would help greatly! thanks for your help again!

The car is starting ok, and your concern is the alarm not working...is that correct? We'll have to find someone who may have a '92 FSM to find out how things are wired.

Do you have another key that you can try and see if it works better? If not, try a search on VATS or VATS bypass for the starting problem. The alarm - we'll have to wait for someone who has more information on that.

VATS is the system used to keep the car from starting unless the right key is used. The bypass puts a resistor in the wiring to take the place of the resistance of the pellet in your key. Doing a search on those will give a much more detailed explanation.

VATS = Vehicle Anti Theft System. It is a box under your dash that measures the resistance of the chip in your key. The chip in your key is a resistor and there were I think 6 different resistances that were used by GM. To bypass the resistor in the key you need to measure your keys resistance and buy a resistor from Radioshack that matches the resistance. Install it inline with the wire that goes to the box from the ignition switch, and then pop the chip out of the key. The car will then start without the chip. I had problems with my 95 and had it disabled. Is your alarm aftermarket? I may be wrong but I thought when the install aftermarket alarms they do the bypass. Anyway if you need it bypassed you can usually have an alarm shop do it for about $50. If you decide to do the bypass just do a search on VATS and you will find a link to the diagram for installing the bypass. Good luck.
