If you put the top down and lock the doors with the key fob, you can only unlock the trunk with the key fob. Once the doors are locked, the trunk release on the door is disabled as well as the trunk release with the VW emblem. If you open the door, the alarm goes off and the trunk is still locked. You need to lock the rear seat passthrough with the key or someone could crawl into the back seat, reach through the opening, and release the trunk with the emergency trunk release. Non US cars get an ultrasonic package in their Eos so you can't even reach inside the car without setting the alarm off.
