Hmmm why dont you just open te trunk with your key, push the back seats down and climb in that way? I just looked and there isnt a seat release in the trunk, but all you have to do to get them down is get a long flathead screwdriver and stick it between the seat and the "back" of the trunk that overlaps over the seat opening...just feel around until you feel the release mechanism...you should be able to push the release to the side and push the seat down. It will take some trial and error, but you should be able to get it.
