Toy Key

The Toy Key is a key given to Henry Townshend by Young Walter Sullivan halfway through Silent Hill 4: The Room. Young Walter slips it under the door of Room 302 in an envelope along with a letter as a gift for his "mother". Later, when Henry goes to the Subway World for the second time, he can use the key to open the toy box in the northeast subway car on the Lynch Street Line platform to obtain the filthy coin.
