Answer
Push on the rear seat cushion towards the rear and pull up. That takes the cushion out. You will see the seat belts have a bolt in them. Remove the two bolts. Grab the rear seat backrest at the bottom and pull upward. Now the rear seats are out. There are three 10mm head bolts that hold the latch on. If you don't go inside the trunk, you will need long extensions on your ratchet. Remove the tree bolts and the trunk will release.
Once trunk is up- remove the clip that holds the lock in place. There will be a rivet or a screw holding this retainer on. Once removed, pry downward and lock will come right out. Reinstall latch and lock and you are done.
