An interchangeable core or ic is a compact keying mechanism in a specific "small format" figure-eight shape. Unlike a standard key cylinder, which is accessible for combinating only via locking device disassembly, an interchangeable mechanism relies upon a specialized "control" key for insertion and extraction of the essential (or "core") combinating components.
