And now when I put the front driver's side one on, the door won't lock, and it also won't shut securely when I have it unlocked, I have to press the lock button for the door to shut securely, but even then, the door isn't locked. Someone help please.

 

when i replaced my frt speakers i had trouble with my panels. had to start with speaker hole first than lift cover raelly hard to push in place than push down it. had to do each side 3 / 4 times before it was secure
