I do have the hatch access in the back thank you. I will experiment with it in case the switch fails.
Regarding the trunk lid. I am wondering for those with this problem, if neodymium magnets might help. I have not looked at the trunk for an appropriate location, but if you install one or two of appropriate strength on the body and a thin piece of metal in the lid, it might hold the trunk down. These magnets come in various strengths and can be very strong and you must be careful working with them.
I recently had my interior vent covers covered and did not want to put screw holes through the vinyl and wanted them easily removable so I screwed two magnets on each side - each 1 1/2 inch long by 1/2 inch by 3/8 inches deep. I then used Gorilla super glue to attach two very thin sheets of metal on the inside part of the vent cover which happened to be overlapped with the vinyl. The vinyl was glued strongly enough that when the metal was glued to it , it did not separate when pulling the vent from the magnets.
The vents held in place from the front mounted magnets alone with no need for any additional support on the top bottom or rear. Plus they come on and off easily. And they held exactly in place when I test drove it even at 55 mph. No vibration or rattle.
