Well worn barrel key fell/popped out of tumbler when I went to start my bike today. Its now stuck between the ´ON and ´OFF position. And I can not get the key back in it either. Anyone out there have any ideas on how to get it back to one position either off or on? I´ve tried WD40, picks and screwdrivers but nothing seems to be working. It also appears that the tumbler moved back into the frame around 1/2 inch.
