Key to the Dead Man's Chest

The Key to the Dead Man's Chest is an item featured in Disney's Pirates of the Caribbean.

Dead Man's Chest
Davy Jones kept the key on his person, until it was stolen by Will Turner. However, James Norrington later took the heart for himself, handing the empty chest over to Jones' crew. Jones unlocked the chest himself aboard the Dutchman, and learned of the heart's disappearance.

At  World's End
Ian Mercer had the key, in his possession.

Later, Jones steals the key back after killing Ian Mercer to reclaim his heart back, but Jack already had it. He tried stealing the chest back, but had a brief fight with Jack Sparrow. Jack later obtains the key after cutting off one of Jones' tentacles and took it to open the chest.
