Location
The Gnarled Key is given to Link by the Maku Tree. Link had to first find the Wooden Sword in the Hero's Cave to open the gate to the Maku Tree. Once the gate was open, Link gained access to the Maku Tree, who gave Link the Gnarled Key. Why the Maku Tree possessed the Gnarled Key in the first place is unknown.
