I noticed that my security light came on and my door locks quit working. Car turned off the security light doesn't flash anymore just stays on solid. Locked or unlocked when the door is opened the factory alarm goes off. I have switched relays around bought new ones and nothing. Still doesn't lock or unlock. What to do now? The only thing I can think of is taking it to the dealer.

Hi BLACKBIRD97, Welcome to 2carpros and TY for the donation

You need to bring it in and have the theft detterent module and body control module checked thoroughly this is where you concerned problems are coming from
