The Magical Key is a special key found in The Legend of Zelda. This unique key has the ability to unlock any Locked Door, and has unlimited uses. This item will make Small Keys virtually useless, as it does exactly what they do, but much more efficiently. The Magical Key is found in the eighth dungeon of the game, Level 8: The Lion. It is one of two items Link can collect in this dungeon, including the Book of Magic.
