The Emblem Key is a key item used in Resident Evil. It is disguised as a brooch displaying the emblem of the Spencer family.
The Emblem Key is used to unlock the office in the 1F east wing of the Spencer Mansion. Its nature as a folded key disguised as another object is similar to the fake key needed to obtain the Armor Key. When obtained, the player must examine the brooch to reveal its true nature.
