A key blank and a key that supports the key blank and includes a grip portion that houses a locking / unlocking display mechanism, and the locking / unlocking display mechanism includes:
A slide member that slides in the longitudinal direction of the key blank in contact with the lock side by inserting the key blank into the lock;
A biasing member that constantly biases the slide member toward the distal end of the key blank;
A lock mechanism for fixing the slide position of the slide member to a different position according to an operation in the rotation direction of the grip portion;
Position determining means for determining a slide position of the slide member,
key. A key provided with a gripping part that supports a key blank and the key blank and contains a lock / unlock display mechanism,
The locking / unlocking display mechanism is
