Before purchasing this kit, I'm wondering if there will be any problems with the locking mechanism.  If I lock the truck, it locks the tailgate.  I didn't see any mention of this in the installation video, yet I saw a vague comment in the feedback section about a truck installation taking an additional hour due to something similar.

I just want to know if there is anything to be concerned with.  I have a 2015 Ford F-150 Supercrew.
