The driver's door should open with the key. Then you'll have to access the trunk through the backseat. There is an emergency trunk release located inside the trunk. To gain access, there is a pass-through in the rear seat. Put the rear armrest down, open the pass-through, and move the release up with your fingers. The release is glow-in-the-dark.
