Abstract: A door lock actuator having unlock, lock and superlock modes includes a rotary input member that positions a pivotally mounted output lever in an unlock position, a lock position or a superlock position. The door lock actuator also includes a pivotally mounted superlock lever that has a bypass position and a block position. The rotary input member maintains the superlock lever in the bypass position when the actuator is changed between lock and unlock modes so that the output lever can be moved back and forth between the locked and unlocked positions and moves the superlock lever from the bypass position to the block position when the actuator is changed to a superlock mode so that the superlock lever is moved to the block position to prevent the output lever being moved to the unlock position.
