Preparing The Handles
First remove the white handle rod clip. This is fairly easy, I pinched the tabs together with some long nose pliers. Keep this part you will need it later.
Second remove the lock rod. This could go very wrong if you don’t take some care. Make sure you do not brake the black part of the lock unfortunately it is only plastic. First lift the white clip and move the rod from under it, then the rod will just drop off. You are left with the white clip inside the black lock mechanism. Carefully squeeze the tabs together and it pops out easily if you get it just right.
