I've searched the forums and elsewhere but I can't seem to find an answer as to how to lock the car with a passenger inside. The other night two of us went to the store. I decided to stay in the car but wanted the doors locked. I kept the fob and used the lock feature on the touchscreen to lock the car. I assumed that when the driver returned I would have to unlock the doors for them but they simply pushed the rear hatch button/release thing and the back opened up. I hadn't noticed them even walking up to the car and it really startled me. They then came around and opened the driver's door with no problem. Is this expected behavior?
