2001 Galant/radio Code?

Hi! Everyone, I Really Need To Find Out The Radio Code. The Battery Died In Car. Got The Battery Charged, Everything Was O.k. Turned The Radio On It Asked For A 4 Number Code. Thank's For All The Help.

I called a nearby dealer with the serial number on the radio and got the code.
If you just pull the cover and look on the bottom of the radio, it mught be really ocward position but if you have kids they can look from that small place and then use that serial number for code
