2016 F150 Door Lock Knob Sticks

This video shows how I fixed a problem on a 2016 Ford F-150 where the door lock knob would stick. The knob would not come up all the way when I would hit the button the first time. If I hit the unlock button multiple times then it would come up far enough. I found this was because the knob was rubbing the inside of the door panel. I took the panel off and put some grease on it and that seems to have fixed it.
