I just purchased a used 2008 Edge and the keyless entry factory code card is not in documentation. Does anyone know where to look for the code within the car? I looked in the fuse box, nothing. Someone mentioned the PCM module - and I have no idea what that is or where to look for it. I don't want to spend $75-125 for Ford to scan it. It defeats the purpose of buying a used Edge (save $). Thanks
