C2.5 - A group of four pirates has a treasure chest and one unique lock and key for each pirate. Using hardware that is probably already lying around their ship, they want to protect the chest so that any subset of three of these pirates can open the chest using their respective locks and keys, but no two pirates can. How do they set this up?

All the pirates uses their individual key and lock for the locking down of each the four sides of the lid of to the chest. Among the pirates, if three of them decides to open their latches, they can be able to lift the top by essentially using the fourth (locked) latch as a hinge to open the top. (We have several solutions or ways to do this.)
