I'm glad to see this conversation going, because I've been trying to figure out how to have the truck lock it's self or be able to do it from the rear hatch area.

I'm a real estate photographer and haul around a lot of gear, frequently accessing it during a shoot. It's frustrating to (my truck is smart key) have all of the doors unlock when accessing the hatch and then have to either go to the front door to press the handle or dig the keys out of my pocket to relock the truck...often done while juggling thousands of dollars of camera gear.

My Tahoe would unlock the hatch only and then relock it when it closed. IMO that's a much better system for someone like myself who uses the vehicle to work.

Any ideas?
