Matter of fact, now you have me thinking about learning it again.
How do I pick the lock on an ordinary, probably 1960s, metal file cabinet? I have one that I snagged from next to a dumpster — 4 drawers, in really nice condition. But can’t get into it, and don’t really want to get into prying and hacksaws, etc, that would do serious cosmetic damage. I’m sure the lock is no big deal, but don’t have a clue how to go about picking it, or trying to obtain a key for it. It’s not worth paying a locksmith to come out and do it, since their basic charge, at least in my area, is more than the cabinet is worth.
