Exhibit: Treasure Chest
You can be sure that anything that would usually be used to open a chest is nothing to do with what’s going on here, so forget the key and the dials etc. The Key Fob, which says “This is the key to the Treasure Chest”, is the key. It contains a magnet which operates the lock when you hold it flat against the brass lock plate with the lettering facing forward. Once you’ve opened the chest, try opening it again with the lid up, so you can see the lock operate.
