The Power Room Key is a lightning-shaped key that unlocks the power generator room at CloudRunner Fortress in Star Fox Adventures. After Fox escapes the dungeon and frees Gradabug, the chief engineer of CloudRunner Fortress, who gives Fox the Power Room Key to turn of the wind lifts. The Power Room Key does not turn on the power, the three Light Gems turn the power on.
The room is full of toxic gas at first but after you activate the power the gas will go away.
