My '17 Boxster (no E&D) will only finish the locking if the boot is opened and THEN the doors are locked. Opening the boot with the doors already locked (eg.--returning to the car with shopping) leaves the doors unlocked when the boot is closed.Hi Mike. No need to relock the car. If you get out, lock the car, then pop either trunk, once you close the trunk, the car should automatically lock itself and set the alarm again. Someone please correct me if I'm wrong, but I'm 95% certain. And it doesn't matter if you have Entry & Drive or not. Even a non Entry & Drive car will do the same, as long as you lock the car, then pop the trunk after, it should re-lock itself once you close the trunk.
