Big Keys,(ALttP | TWW | TMC | TP | ALBW)[1] also known as Boss Room Keys,(Series)[2] Nightmare Keys,(LA)[1] and Boss Keys,(OoT | MM | OoS | OoA | PH | ST | CoH)[1][3][4] are recurring items in The Legend of Zelda series.

Location and Uses

Big Keys are one of the three standard dungeon items, the other two being the Compass and the Dungeon Map. They are generally harder to find than Small Keys and are used to open the big door leading to the boss' chamber.

A Link to the Past

In addition to opening doors, Big Keys are also used to open the Treasure Chests containing a dungeon's item in A Link to the Past. Doors unlocked by the Big Key may not necessarily lead directly to the boss.

Link's Awakening

Nightmare Keys open access to a Dungeon's Nightmare in Link's Awakening.

The Big Key from the Goron Mines must be put together by obtaining the three Key Shards from the Goron Elders in Twilight Princess. In the Snowpeak Ruins, the Big Key is replaced by the Bedroom Key, as said dungeon is actually the mansion residence of Yeto and Yeta.

Link must carry the Boss Key in his hands rather than in his inventory in Phantom Hourglass, making him unable to attack and vulnerable to attacks.[5]
