Today, my security light started coming on preventing me from starting the car. Nothing on the car has changed since. If I wait about 5 minutes, it stops and I'm able to start the car. I've tried cleaning the key to no avail. It's a 95 Camaro 3.4L.

 

my 96 does this from time to time.

might be a silly but which part of key are u cleaning? it not the key so such much as the little square reader on the key that needs to be clean around the edges, an most times i hvae to wiggle the key to make sure i got a good contact.

if all else fails gona have to get a new key from a dealer or ebay with the same code as ur key. seach for my thread on this an it give u the ebay link an also in thread tell u how to get th ohms of the key.

 

If cleaning the key's resistor pellet works, great. If it doesn't, then the problem is most likely the wiring inside the ignition lock. Replace that and make sure the new keys are cut with the same resistance pellet as your current key. New keys are generally bought from a dealer, but any locksmith who carries the resistor-pellet keys can cut it for you as long as they match the old key.

 

Try using an eraser to clean the pellet. If it doesn't work look up vats issues and you should be able to find out whats going on.
