Hmm, before I forget ... you also have to put on the knocker lock. The only trick with that one is a little spring that slides in vertically behind it.
Here's a pic of it in place to show its location. I'm holding it 'cause it'll fly off if I don't ....
The spring fits into the little vertical channel behind it. I found that I had to press the bottom of the knocker lock into position, and then pry the top away from the chassis a bit and drop the spring into place, then press it down so I could push the top of the knocker lock into place. If that makes any sense.
