Hah, I love this sort of story. Recently I was on site and we needed some electrical as-built drawings. They’d been stashed in a tool box, which was locked (and pretty well designed to protect the padlock from bolt cutters / angle grinders). Unfortunately one of the guys had taken the key with him and it was now a two hour plane flight away. They already tried and failed to cut the lock, and were getting an angle grinder to just cut in through the lid (it was ~3mm steel sheet, so hardly impenetrable, but destroying the toolbox would not have been ideal) when I pulled the pin out of the hinge and recovered the drawings that way.

Turns out watching Pirates of the Caribbean wasn’t a waste of time after all. ;)
