Newbie question. In my quest for knowledge on these trucks, i cant seem to find an answer in my manual. How do i get the doors to not autounlock when i place in park. I go to St Louis occassionally and prefer my doors to not unlock when im in the city.

I don't think that's an option. The older trucks had a lock with speed but never not unlock.

The older trucks had the option to only unlock when you shut the truck off. I want to say it also had the option to never auto-unlock, but I would have to try it and see.

The new ones might not have those options.

You might be able to do it with a Tech2.
