Ford Focus CD-6000 Radio/CD Player Security Code?

PLEASE could someone assist me with this? I own a Ford Focus 1.6 (2004 model) with a CD-6000 sound system... Recently I had to recharge the battery, and as a result the radio has been locked. I've moved so much in recent months that I've now lost my service manual and keycode for the radio! I can provide you with the vehicle details as well as serial number. Otherwise, is there a site where I can generate the code myself? I live in South Africa, and unfortunately in a small town with no local Ford dealership. I have called dealerships in the bigger cities, but they refuse to help me unless I drive there... I would really appreciate any assistance! Thanks! :)
