The Golden Key is an item which unlocks the Golden Chest in Sanctuary. This chest contains weapons of purple or magenta rarity, and relics may be blue or purple. All loot is scaled to the character used to open the chest at the time. Golden Keys are single use, impossible to trade, and are not dropped as part of loot in Borderlands 2.

An easier alternative, for PC users, is to use an edited profile.bin file that generates infinite keys.
