I tested mine, curious if my having the keys at the drivers door would allow someone at the front passengers door to open the lock/door before I did so....it didn't.
Of course, with the keys on your person, you may open any door in any order, including the rear hatch.
What I have noticed is that if you use comfort access to open the front passessnger door first, it will open the drivers door at the same time...or so it seemed to me.

Quite trick, me thinks.....
