Each rotary lock element includes an inner peripheral hub disposed on the shaft and including a radial bore extending from an outer periphery of the hub to an inner periphery of the hub, and an outer peripheral wheel surrounding the hub. A shaft engaging member a wheel engaging member are disposed in the radial bore, with the wheel engaging member extending partially outward of the outer periphery of the hub for engagement with one of a plurality of inner peripheral pockets in the wheel to rotationally fix the wheel with the hub. When the locking shaft is moved from a normal operating position to a code change position, the shaft engaging member of each dial is partially receivable in a corresponding recess in the locking shaft, and the wheel engaging member is receivable into the radial bore to rotationally disengage the wheel from the corresponding hub.
