What is the meaning of a skeleton key tattoo?

The skeleton key symbolizes the uncovering or unlocking of secrets and mysteries. Coming from a time when keys of this sort could open just about anything from treasure chests to old attic doors, skeleton keys go hand in hand with intrigue and adventure.

Skeleton key tattoos may symbolize the closing off or breaking free from a troubled past or difficult life event. Skeleton keys and other lock and key tattoos can also symbolize love that's a perfect fit or a key to the heart, where each person in a couple sports a piece of the symbol to form the complete tattoo.
