i think hes saying, that i wont pass a wof if i dont have my interior lock knobby things, becuase i wanted to take the knobs off my interior locks, so if someone smashed the window, they still wouldnt be able to unlock the door, so theyd have to climb thru the window etc. simple solution, put on for wofs, take off for the rest of the 5.99 months untill the next wof.
