Like many others I have been staring at the non-locking rear hatch in anger, and occasionally opening it when the truck was locked to have the alarm go off.
I finally took out the panel, cleaned and lubricated all the connections. Got it working again, we will see for how long.
While I was in there, I lubricated every moving part I could find, and re-tapped some wires and checked to make sure everything was secure before buttoning back up.
Now, on to fix the drivers lower heated seat not working!
