ok i have removed the whole ignition from the bike, but dont know how to get the barrel out from the rest of it. any help would be greatly apreciated

well, i seem to have lost my keys to my recently purchased 1990 TZR 125. I was wondering if, to a complete mechanical virgin like myself, is it difficult to change the ignition barrel and the one in the seat and petrol tank too? I am devistated as i was so proud that it lasted on my 700 mile adventure up and down the country (which is pretty much all the riding i have done on it so far), and now i cant even ride it.
