The latch plate has a first end extending beyond the casing and a second end inside the casing. An engaging wheel is rotatably received in the second hole of the mount plate and releasably engages with the second end of the latch plate. An actuating wheel is rotatably received in the first hole of the casing and is rotatable to a position to engage with the engaging wheel to rotate therewith. A switch button is mounted outside the casing and securely attached to the actuating wheel to rotate therewith. When the auxiliary lock assembly is in a lock position, unlocking from an outside of the door plate is prevented when the second end of the latch plate is engaged with the engaging wheel.
