95 Monte Carlo's are equipped with GM Passkey II. A wire runs from the computer up to the ignition switch and back to the computer (The 2 wires run into the steering column inside an orange shroud. The wire measures resistance from a resistor in the key. If you have a loose connector or if the resistor on the key is worn down... the computer cannot read the correct resistance and thinks the car is being stolen. If the computer cannot read the resistance at startup, it will disable the starter and fuel injectors for three minutes. The easiest fix (although it disables this security feature) is to measure the resistance in your key (the little chip on the part of the key that goes into the ignition) using a multi-meter, then buy a resistor from radio shack of the same reistance; then hook the resistor to the two small wires in the orange shroud underneath the dash going into the steering column (leaving the wires coming out of the steering column dead). This way, the computer always reads the correct resistance. If you're worried about losing your security feature, you can also place a toggle switch on the wire to disconnect the resistor when needed.

If you don't want to get this hands - on... take it to a dealer for a new key and possibly ignition switch (40 for key / 90 for ignition switch)

Because the VATS (Vehicle Anti-Theft System) Chip in your key may be dirty or you might need a new one. I'm having the same problem and the Chevy people are trying to charge me about 90 bucks to fix the problem. Try dipping an eraser part of a pencil in alcohol, rubbing both sides of the chip with it and waiting five minutes. You may need to get it fixed quickly or your car may not start after a while.

Because I'm cheap, I sprayed some brake clean into my ignition lock cylinder and on the key and ran the key in and out of the ignition about 100 times. That was three years ago and I haven't had a security light since. Or, if you feel uncomfortable with that, and you have a second key, just switch keys.

mine goes off for everything. when my alarm was triped, when my ABS is messed up, when there is anything wrong with my car other then oil, gas or the brake light. for me its the catch 22 light. if you recently got in a fender bender it can be a pinched or severed wire were you were hit. That is why my ABS was inop, after i fixed it the light finally stoped bugging me. hope that helps give you an idea were to look, my owner manual actually had some good info in it for once! Frank

hey guys i just went through all of the above with the security light very easy to fix i just went to the source which was radio shack and bought a resister that's brown red red pulled the wire apart that runs to the ignition this is simple its yellow n has 2 white wires inside put 1 end of the resister on 1 side the other 2 the other white wire and wammo she works so 2 all good luck n don't think 2 hard cause my head hurts time for a beer!!!!!!!!
