There is a way...
Remove the rear license plate, find the center of the panel drill a 1/4" hole
about two inches down from the top of the panel (should be behind the plate when
it is put back in place). If you are lucky the hole is already there.
Then you can use a screw driver to turn the latch on the trunk.
Local auto parts store should have a plastic plug you can put in the hole if you
Be careful when drilling to not damage the latch when you get through the sheet
Admittedly it creates a hole in the sheet metal, but it is behind the rear license plate, and it is small.
