Some of those did have an internal button release, so if you can push the external button and nothing is opening, I feel that it will be a failing lock return spring, you can try pushing down on the boot as you push the button, from memory the fuel tank is behind the rear seat, but if not and it has the split seat option get into the boot and release it manually otherwise you may have to drill out the lock and manually probe the release to try and trigger it open, obviously this will destroy the lock so it is an option of last resort, persistence may release the lock and when open you will have to examine the mechanism to determine if it can be repaired or needs replacing.
