get a lil thicker pin and drill the hole out towards the inside of other side of the pin so as to not drill too much out on the short tide and buy you a thin shank masterlock of your own choosing or a numerical lock and have your own combo.... then NOONE would have the key unless they take 5,000 masterlocks with them to undo it...
