Therefore, it will always be in an unlocked position and cause the door to lock regardless of what number of times you push the button for opening.
Additionally, the issue could be caused by an electromagnet that is damaged or a wire that causes the lock to not function.
This kind of issue can be caused by contact with water, force blunt, or extreme temperatures.
