how do i disable car security on a 01 cadillac its causing my car not to start
If the battery is fully charged then do this: make sure all of the doors are closed, on the drivers door use the key to lock then unlock the door, that should reset the system.
If you're trying to use a new or replacement key, it must be a transponder key. It must also be programmed into the car's computer system so the car will recognize the key and allow you to start the engine. HTH. -Jim
