Room 500 Key

The Room 500 Key is a key Travis Grady finds in Riverside Motel in Silent Hill: Origins.

During his exploration of the motel, Travis unearths more and more pieces of his painful past, thanks to the items and memos he finds scattered around the place. One of these items, a wedding ring, helps him to complete the Calendar Puzzle, allowing him to get the Room 500 key.

The key unlocks the door to Room 500 in the Otherworld version of the motel, leading Travis to a boss fight.
