One. How to repair a door handle that doesn't return to its original position when operated manually.
1、Internal locking mechanism malfunction.
You can first try to unlock the door with a key to see if the internal lock mechanism is binding. If there is a sticking or resistance when turning the lock, it may not return to its original position. In this case, you can add a small amount of edible oil or pencil lead powder into the lock to lubricate it and restore its function. If the handle is stuck and not returning, try turning the key from the inside.
2、The holes are misaligned.
If the holes are misaligned, causing friction instead of rebound, try realigning them first. If this does not work, remove the handles, unscrew them, and realign them from the inside. The same procedure applies if the misalignment of the front and rear panel connection holes prevents rebound.
3. Malfunction of the locking body itself.
If the door handle does not return to its original position due to a fault in the lock mechanism itself, it is necessary to disassemble the entire handle and install a new one to avoid future problems.
Two. How to remove the door handle
First, use a tool to unscrew the screws that secure the handle's side, typically three screws. Two of these are located on opposite sides of the handle, and are used to fix the door lock. The third screw is used to position the handle.
First, unscrew the two screws on both sides of the door lock. While unscrewing, use your hand to hold the doorknob to prevent the screws from loosening and falling suddenly, which could injure your feet or damage the floor tiles or wooden flooring. once the screws are removed, you can also remove the doorknob and the cover. At this point, you will see the screws used for positioning, which can then be removed to disassemble the entire lock body.
