I disconnected the electric to my 2002 GMC sierra truck and now the radio theft device has locked .?
We had to replace the fuel pump in my car yesterday and the battery was disconnected while we worked on it. I don't know what the code is to be able to use the radio now that the truck is repaired. I called the car dealership and they said they could call GM to get an over ride code but that it would cost me $90.00. Does anyone know how to retreive the code or over ride the system so I can use my truck radio again?
