The motel room key is a tool used to unlock the door from the motel room that is shown on the key's tag. The key has no other purpose, and cannot be used on any of the other doors in the motel. The room number that is shown on the key's tag will display one of six possible rooms randomly for each playthrough.
The room itself is used to continue the progress of the player's journey. After resting in the room, the player will be able to select a new route from their Map Book.
It costs DM 20 - 40 (the price of the rooms will increase as the player progresses), and can only be purchased from Motels.
