S4 TII - Key won't turn in driver's door
 

The driver's side door handle (entire inset piece) is loose on the FC I bought. When I open the door, I just have to be careful not to pull too hard. When I put the key in the door, it won't turn at all.

Is the handle assembly broken or could it just be disconnected?

The handle is only attached by 2 nuts, so one of them could be loose.

The lock could be messed up. Mine sticks when trying to lock it. If I try it enough, it will go.
