On mine, I had the upholstery guy build in access holes in the back seat, so I can just reach in & pull the pin, if necessary. Also, I moved my battery switch under my back seat, just in case I kill the battery.
Do you have external hinges? You can always pull the pins on the hinges, and slide the hatch backward enough to get your hand in and pull the pin.
Otherwise, I have heard guys just muscle em up & break em, or pull the screws out. There was a thread on OSO a few weeks back, where the guy had this very problem. If you perform a search, I bet it's still there.
