Keys of Liberation

The Keys of Liberation are the keys that allow Henry Townshend to leave Room 302 in Silent Hill 4: The Room. Henry can find them after breaking down a wall using the Pickaxe of Hope. Breaking down the wall reveals a hidden room in which Walter Sullivan performed the ritual that allowed him to create his twisted "world" and separate himself from his physical body. Examining Walter's suspended corpse reveals the keys are kept in his coat pocket, and after taking them, Henry can dispel the chains that bar his exit of Room 302. These keys are said to have a hand in passing through from the Real World to the Fog World, and even the twisted Otherworld versions of Ashfield.
