What Is the Symbolism of Skeleton Keys?

From pendants to fine art, literature to songs, key symbolism permeates cultures worldwide. A key opens a lock and thus provides access. Skeleton keys, sometimes called passkeys, have usually been crafted or altered in some way to provide access to more than one lock.


The skeleton key got its name because of the shape of the opening it fits in. Rounded at the top with a narrowing triangle at the bottom, the keyhole resembles a stylized skull. Another name for key is clavicle.


Keys provide access to locked rooms, cabinets or boxes. Thus, key symbolism indicates opening or discovering that which is hidden or secret. Because skeleton keys usually can open more than one lock, they are often considered a powerful symbol.
