|Doctor's House - Corpse, Village (Forest) - Corpse|
|Crafting||This item cannot be crafted.|
|Notes||Unlocks locked door in Doctor's House.|
It unlocks the door to the southernmost shack at the Doctor's House. The Rusty Key can be obtained by killing the Madman hiding inside the second building at the Doctor's House or in the Village (Forest).
- The door to the shack can also be broken down.
- The key can also be looted from the Madman in The Village, this is presumably an oversight.
