Hey all you MC21 guys! In a nutshell, if nsr250eeeee is in the USA, Honda has no codes and most locksmiths have no codes. May be the same situation in other countries, too. The correct key blank is available from Honda for a couple bucks, #35121-MN9-611. Buy 2 and keep a spare. Code is marked on the barrel of the lock assy; Andy already gave removal instructions. With your new key blanks and with barrel in hand, try your local "real" locksmith, like the one Matt described. If you still can't get the keys cut then kindly pm me and we'll get this squared away right quick, eh. You do want to ride again, don't you?
