Terry, the rubber hammer is a good idea, i'm sure that would have helped, but i got it out last night. once it starts to move at all, progress is quick. sad to hear the cylinder may not be ok if a key wont go in. its a key from a 40 pickup. the cylinder looks good, no damage, so no one is fixing them? i see from forum searches its a FK series, later lock, all brass, no plating. any idea where to send it to a lock doctor?
