Archives Key

The Archives Key is a key Travis Grady finds in the Otherworld version of the Cedar Grove Sanitarium's basement in Silent Hill: Origins. In order to get it, Travis must go through an elongated process:
 * The first time he sees the key, it is found in the bottom of a tub in the female hydrotherapy room (2nd Floor, Fog World version). Travis needs to empty the tub, otherwise the hot water would scald him, so he drains the water out, along with the key.
 * The next time he finds the key (though he can't see it), it is stuck inside a toilet in the last stall of the women's restroom (1st Floor, still "normal" version). He flushes it, sending the key to the basement.
 * At last, after changing to the Otherworld version of the building, Travis makes it to the east pipe room of the basement, where the key is lying in a drain and can be picked up.

The archives key unlocks the archive on the 2nd Floor, where Travis can find items, a mirror, and more clues about his past.
