Hi all,

I have a 2003 Chevy Malibu LS. Occasionally, my theft system light will come on when I start my car. I usually have to wait 10 minutes until it deactivates. I don’t understand why it does this!

If you have an aftermarket remote start I would look at that first as a source of the problem.

Maybe it is your key. Try using your spare key.

I have never had a anti theft system.

I’ll be getting the key checked out. Thanks all!
