The Speedboat Key is required to use the most western exit after completing the mission, which is the speedboat located in the Seine river, on the west side of the palace grounds. To get to it, you need to walk past the helicopter and down some stairs behind it.
The Speedboat Key is located on the second level of Palais de Walewska, inside the smaller western room out of the three rooms with entrances from the northern corridor overlooking the catwalk on the ground below. It is lying on the north side of the desk which is found on the north side of the room.
- There is also a speedboat to use as exit for the World of Tomorrow mission, but that one does not require a key. This is presumably because that one belongs to Agent 47 or the ICA, while this one don't.
