Key to the Bunker
The key belonged to the Men of Letters and was kept in a box which was decorated with their crest - the Aquarian Star. Inside the box is "the key to where every object, scroll, spell, ever collected, in a thousand years, under one roof". Basically, the Men of Letters had stored all the supernatural knowledge that they had possessed. If the Box were to be hunted down by any "evil being" (demons, monsters, etc...) it would be safe when stored in the area where they had placed all their scrolls and secrets because the area itself is branded with symbols to ward off every kind of evil ever created.
It is now in possession of the Winchesters after their grandfather, Henry Winchester, died at the hands of a demon, Abaddon, while the demon was out hunting for it.
