2003 Pontiac Grand am Radio?

[Andrew C]

Is it true, if you competly unhook the battery in a 2003 Grand Am SE1 it will need to re-programed or will lock and only a GM dealer can unlock it?
The radio brand is a Moonsoon with the amp.

False, you may lose the pre-set stations, just reset them.

If its off for a long time yes you could lose the code. If you are just changing the battery no it should be fine. We have cars get dead batteries and they sit for a while before we find then and we don't have to reprogram them so its safe.
