I have a cupboard my in-laws brought back from France in the 60's (the piece may actually have been made in Germany, but no one knows for sure). Of course, the key to the drop-down shelf was lost during a move, and, although I have purchased about a hundred old barrel keys, I've been unable to get the lock open.
Some keys move an internal lever 1/4 turn, but then is interrupted before completing the last 1/4 turn.
I need some good instructions for impressioning a key for this lock. I received a number of blanks among the keys I bought, so I have something to work with. I have read a number of articles on how to do this for regular pin locks, but have been unable to find anything on barrel-keyed furniture locks.
TIA for your help.
Regards, Allan.
