I made a quick video of the operation of the door latch system.
One thing to point out that the video doesnt show is to give some more detail about the lock. This is the lock that came with our ACS ignition switch. This works out great because the same key will fit our baggage door, pilot side door, and ignition. I made a metal bracket to give it more stability. There are some photos which show the final product. Also, the door lock was placed on the aft side of the door handle, which means the door handle covers the lock on the outside of the door. This just kind of ended up this way and fortunately worked out just fine. There is a little play before the lock catches the gear so in order to lock the door, the handle must be turned about 30 degrees to expose the lock. It actually looks pretty neat on the outside because the lock is almost completely hidden when the door is shut. Probably very slightly more aerodynamic like this too.
