You'll get a new key, but they're only held on by 3 allen head bolts, then job done. This one comes with a new seal as well.http://www.ebay.co.uk/itm/Motorcycle-Motorbike-Fuel-Tank-Cap-Cover-OEM-Style-for-Yamaha-FZS-600-1998-2001/291848621661?hash=item43f3888e5d:g:9IoAAOSw0UdXtHjR
With your other hand (to the one turning the key) have you tried pushing down at the front of the Cap gently (front of the bike side), helps the mechanism to turn more easily?

On the basis that there is fec all to the mechanism other than the lock barrel and a spring loaded plunger that latches the lid of the tank shut, chances are, opening the cap (which pushing down on the cap to avoid breaking the key) followed by liberal amounts of WD40 and key twisting into the barrel and mechanism to clean it all up and then a load of grease to keep it moving freely, will probably solve the issues.
tis good in theory but in practice if it's worn out it's worn out! if you can't remove/replace the tumbler pins then I guess it's focced!
