The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM. (Theft Deterrent Module) The TDM is what tells your computer that the correct key is being used and that it is "OK" to allow the vehicle to start and run. These 3 parts must be in CONSTANT communication. If the key is in the ignition, then these parts are sending important signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, (normally due to a failing/broken part) the car goes into antitheft mode. The car misinterperates this and thinks its being stolen or hotwired because it is NOT getting that signal from YOUR specific key. There is where the security light turns on and shuts down your vehicle. So basically, if that light is on, your system has some sort of failing part. This can start as an intermittent "no start", to your vehicle not running for days at a time, to the vehicle NEVER starting again. The problem is electrical and computer based, so don't count on an easy reset button, or the problem fixing itself. The hard part is isolating which part is the problem. You can spend a thousand dollars through a mechanic very easily. I have had great luck with bypassing the entire system. This way the problem will never return. It actually CAN'T ever return because it is eliminated. This can also be done yourself at a much cheaper cost. Read through this link very carefully. You'll find alot of information and pictures, along with ways to help you fix this.

SOURCE: 1995 Buick Riviera SC: traction and the security light
traction switch is located next to drivers left knee on bottom of dash....you should be able to turn off the traction light there by just turning on the traction control.....the security light is telling you that there is a problem with your security system....could just need a new key with a new computer chip....make sure the key is clean and dry when using so it can read the chip....the security light comes on whenever your start the car and stays on for approximatley 2 minutes and then should go out....it is just a reminder....try this and see if it works....lock the door using the power switch on door.....close door and see if the security light comes on....watch and it should go out after about 2 minutes...if it does then your alarm is activated and working....to disarm you need to unlock the driver door with the key...anything else will set the alarm off and the lights will start flashing and the horn honking...after you set the alarm off you will always have to use the key to unlock the drivers door to turn off the alarm and reset the security system.

Let the car sit undisturbed for 10 - 15 minutes, then try to start it. Check the owners manual if you have it. Sometimes, on various cars letting them sit awhile will allow the system to reset itself. On others sometimes rapidly turning the key from off to on, without turning to start 3 to 8 times within 10 seconds and then on the last turn to the on position leave it there until the horn chirps, at that point turn the key directly to start, or turn off first and turn to start. If all this fails, a GM dealer can reset the system.
