I changed the battery on my 2001 cadillac deville, and now my radio dont work. it displays theft lock can i unlock it?.. how?.. help please!.
IF when you purchased your car you didn't set your own personal code you will have to take this to your local GM dealer and they can pull the code that is set at the factory and unlock your radio.THe proceedure for setting your own code then unlocking radio is in your owners manual.The dealership I worked for did this for free.
