My security light on my car wont start what to do on 1996 Chevrolet Lumina

My car is a 1996 chevy lumina

Asked by for the 1996 Chevrolet Lumina
You did not say if the car will start or not. Assuming you have a no start condition along with a security lamp, the problem typically requires the replacement of the ignition lock cylinder and keys. If you have another ignition key you want to try it first.
