If all 4 doors are unlocked, then yes you can open the trunk as it sits there without the fob in your pocket...at least that is the case with the '14 as I recall. I don't like that. If I'm waiting for the kids to get in the car, someone could easily pop the trunk while I sit there playing with the phone and run off with anything back there before I have a chance to realize it. Bad feature. Should be with fob only from outside.
