Our AD trucks only have one keyed lock. Passenger side. You lock the drivers door (push interior handle forward) slide over exiting via the passenger door and lock. The leading theory I've read is this keeps drivers out of the traffic lane when unlocking the door. Sounds good to me.

What is “AD”? Also, are u telling me my truck comes like this….passenger side lock only?
I am going to try and do the drivers side push down lock method. I did not know this. Doesn’t show this in my O&M for the 52.
Thnx!
