Any repair shop (body shop or auto repair shop) should be able to handle trunk repair. You may want to look through your local yellow pages. Have you tried spraying a lubricant into the latch assembly, sometimes it help to lube it and use a screw driver to flip latch/lock to locked position and then release with key or trunk release button several times. Rust is prone to jam locks and latches. Most local auto parts stores carry these latches in stock, and it is relatively easy to change out. Let me know if you need further help.

There is an emergency release on the latch itself inside the trunk.Should have a red tap on a small cable.you will need to crawl into the trunk to release the latch.Good luck!

No it don't, to replace fuel pump, gas tank will have to come down.

Latch may have come loose and dropped, look at paint makes to confirm this. The latch may be already tripped, you need to unlock and at the same time lift the fall piece with a screw driver.
