Would replacing my battery on my 04 Grand Am GT shut my stereo down? My owners manual states it has a passlock system, and when the key is removed from the ignition a little red light starts flashing on it. The manual also states that the stereo uses part of the VIN to be set, but being I bought this car used, I don't know which numbers to use. I tried the last 4 numbers of the VIN with no luck. Does anyone know how to reset my stereo once the battery is replaced or should it reset itself? If the latter is the case, maybe I have another problem then. It's a Monsoon stereo if that makes a difference. Any help will be greatly appreciated.
