Hello, can someone tell me how to remove the thing in the lock. Have the feeling I only have to solve the lower part and then the problem would probably be solved but unfortunately it is difficult to solve the two hacks at the same time. And I have the feeling that there is tension on it, the thing bangs me through the area when I manage to solve it or there is no danger? The pictures from the side are the same, whether I turn to Open or Close.
