Abstract

A key holding device includes a key cylinder capable of retaining an auxiliary key which is a vehicle key that is not a master key. A rotor is rotatably arranged in the key cylinder. The auxiliary key is insertable into the rotor. A tumbler is rotatable with the rotor in the key cylinder. The tumbler holds the auxiliary key in a manner irremovable from the key cylinder in accordance with the rotational position of the rotor. A key lock mechanism is capable of locking the rotor in a state in which the tumbler holds the auxiliary key in a manner irremovable from the key cylinder. A control unit selectively switches the rotor between a locked state and an unlocked state by controlling the key lock mechanism so as to permit removal of the auxiliary key when the rotor is in the unlocked state.
