Insert the part outside into it, and screw down the knob to see if the square tongue can be turned out normally. If there is no problem, then the lining board of the lock body (namely the exposed part of the lock body installed on the side of the door door) should be fixed with the matching screw of the lock core.       Maintenance of separate locks       When opening the door, do not force the key to turn the door.
