Do you get the location key for your starting location at setup?
The designer's later ruling and the rulebook's Moving your pawn step both say the key is claimed on entering a new location.
No. Keys are claimed only when you enter a location on a move, so you must leave and come back to the starting location to take its key. Searching also needs that location's key, so you cannot search there straight away. The designer later reversed an older ruling that let you start with it.
