Sometimes you can reset the security light on a Monte Carlo. Open all the doors and then lock them and close them. Next, use the key to unlock the front driver's side door. If this doesn't work, the car should be taken to a mechanic who can diagnose the problem. When the security light goes on, it can mean something in the security system is failing.

Changing the brake light switch in your Chevrolet Monte Carlo is quite simple. The brake light switch simply plugs in and out.

This is the light for your security system. Shows that it is working.
The security system shuts the whole car down so that it cant be stolen.
How do you take a rheostat out of a 2003 monte carlo
The light may turn on due to uncleanliness of the start key. For this reason, it must be cleaned.
kind of had same problem but turned out to be something else but a guy who had a Monte Carlo pulled up to us and told us if our problem was the security light to turn on the ignition to the on position do not start car and leave for 10 minutes and then turn off and then try starting car and that should reset the security light he said it happened to him and that is what Chevy told him to do and it worked for him.
unhook a battery cable for about 3 minutes and re-hook.
