The correct answer is: Multiplex Key Blank

In a multiplex key system, the term for a key blank that is utilized is known as the multiplex key blank. This type of key blank is designed specifically to work with a multiplex lock system, which allows multiple different keys to operate a single lock or multiple locks with an efficient design. The mechanics of these systems typically involve various configurations that permit distinct combinations and keying to ensure security and flexibility. Each key blank in a multiplex system is carefully designed to match the intricate keyway of the lock it operates, ensuring reliability and compatibility. Other terms in the choices, such as composite keyway and key way ward, refer to different concepts in lock design and key operations but do not specifically denote the key blank used in a multiplex key system. Therefore, the term multiplex key blank accurately describes the component in question, highlighting its specialized role within the broader framework of key and lock mechanics.
