im after a few new keys for my MK1 Focus RS as i only have one! problem is it is not a genuine key and i dont no the correct part number for it can some1 tell me is this is the correct key??

ebay number 370370589149

there 60 odd quid each at ford plus the blade and thats ridiculous,

Ford gave me these numbers

blade 1063692
brain bit 1233541

but i think these are jsut their catalougue numebrs or something

car is a 2003
i post this in RS section already but no help as yet, if someone could give me the number or there genuine key that would be great

thanks luke
