I recently disconnected the car battery not knowing that the factory radio would require a password in order to use it again. Apparently the radio has a anti theft system that will lock the radio. Does anyone know how i could get it to work w/out having to take it to the dealer? thanks ---

Some previous owner might have written the code on the back of the owner’s manual. I have also heard that some nice dealers would give you the code over the phone when provided with the VIN. ---

You may also find it on a sticker in the trunk. That sticker or the number in the manual may not work if the owner had changed the code, but I would guess not many change the code.
