tried putting oil into the barrel didnt seem to do anything and the other keys are just as bad any ideas of a price i will be looking at for a new key with it being cut aswell?

not sure if i have this in the right section but here gos just brought my self a fz6 2006 model great bike the only problem is the ignition is a pain in the back side to turn on sometimes it works straight away others it takes ages any ideas why it does this and what i can do to sort it?as i dont really fancy having to buy a new ignition kit as im sure it wount be cheap.
thanks
