Apartment Keys

The Apartment Keys are a set of keys Henry Townshend must obtain in Silent Hill 4: The Room. They are found hanging on a wall inside of Room 105 of the Apartment World. The room belongs to the superintendent of the apartment's real world counterpart, Frank Sunderland, and can be used to unlock every apartment inside of the building excluding Room 303.

The keys cannot be used to enter Room 105 during Henry's second visit to the Apartment World, as the door is locked by other means.
