In the original versions of the game, the Armor Key can be recovered from the mansion's
greenhouse, which is inhabited by a
mutant plant. In the Arrange Mode present on the
Director's Cut release, the key has been placed on the
east terrace next to
Forest's body. In the
remake,
Chris and
Jill can find the Armor Key resting in a pedestal in a room guarded by a trap. If one of them pulls the key from the pedestal, a trap involving a suit of armor will activate and close in on them with rotating blades on a shield. To bypass this trap, they must find the
Imitation of a Key and set it in place of the Armor Key. Regardless of where it is found, the Armor Key works the same. Once collected, it will unlock many doors in the mansion, including rooms that lead to collection of the four
Death Masks. It is also used to unlock a room leading to where
Richard Aiken is laying wounded by a snake bit..... I hope this helps :)
