"A key with a dead scorpion attached."
Scorpion Key (サソリのカギ sasori no kagi ) is a key item in Resident Evil 7: Biohazard.
The Scorpion Key is used to unlock doors with the scorpion decoration. One door connects the Main Hall to hallway that leads to the Processing Area, and one door is on the 2nd floor of the Main House and opens up Grandma's Room. The key is not required to pick or use to complete the game.
The Scorpion Key is located in the Processing Area, shoved inside a corpse on the table.
On Madhouse difficulty, the Scorpion Key is locked in the bird cage located in the Main Hall and can be acquired at the cost of 3 Antique Coins.
