During the war in 1775, soldiers found and opened the Black Door in the Drowning Cave, thereby releasing demons. In order to seal the door shut, Benjamin crafted a padlock and a key from Whispering Iron — which he claimed had been tempting him. He later crafted numerous other keys, which were hidden in Keyhouse Manor for many generations. The keys can be exchanged between owners, however they must be willingly given, and cannot be taken from the Locke Children by force.
Note: ⸸ indicates that the key solely appears in the Netflix series; they are not mentioned nor appear in the graphic novels.
These keys can be seen in art, but were unused. Names are not official.
