- For tips on obtaining Key Molds, see Guide:Farming Biome Keys or Key Molds.
Biome Keys are Hardmode items used to open the Biome Chests in the Dungeon. Opening a chest consumes the key. Though unusable until Plantera is defeated, they can be dropped at any time during Hardmode. On the Desktop version, Console version, and Mobile version, each key has a 0.04% (1/2500) chance of dropping from an enemy in the key's respective biome. On the Old-gen console version and , they are not dropped directly and must be crafted from versionBiome Key Molds.
Any enemy in the biome that will drop coins when killed can drop the key, not just biome-exclusive enemies. Keys cannot be dropped by Meteor Heads, enemies spawned by a statue, critters, or any enemy spawned by a Celestial Pillar in the Lunar Events . Additionally, enemies in hybrid biomes have a chance to drop any key from their composite biomes. The biome is determined by which biome the player currently is in, not the enemy killed.
Any Biome Key dropped prior to defeating Plantera will display the tooltip "It has been cursed by a powerful Jungle creature" and will be unable to open its respective chest until Plantera is defeated. However, cursed keys are usable in worlds where Plantera has already been defeated.
