THE CAR SECURITY LIGHT CAME ON AND NOW STAYS ON BUT I DON'T HAVE A SECURITY SYSTEM.
1997 Buick Century • 125,500 miles
It just popped on when I started the car. The car ran fine. I turned it off and on about 4x and it started each time fine.
You have a factory security system i posted a description of how it works.
Thank you. What do I need to do now? Purchase another key? My spare key that I've never used since I got the car 5 years ago didn't help. The light was still on. Am I not going to be able to start my car eventually?
The most common reason is the wire going to the ignition cylinder breaking.
I posted trouble shooting for your issue let me know what you find.
