Couple Dumb questions...

Run the front seat forward as far as it goes to give you more room to remove the rear seat. I usually use my foot to kick the rear seat bottom rearward while I lift up a bit on the top edge. As was mentioned, once the bottom is out you can see the attaching point on each side that hold the upper section. Once it's out, you can remove the cardboard filler (if it's still there) and gain access to the trunk. I use a ratchet with 4 feet of extensions and a 1/2" socket to take the latch loose. Then the lid will come up and you can pull the lock cylinder to get a key made. Hood latch cables can be a pain. First I would lube everything in site while I work the cable as much as it will let you. If there is a kink where you can reach it, try to straighten it out a little and try again. If it still won't release, I would try to take apart some of the front end parts to gain enough access to either trigger the latch or unbolt it. Sometimes there is a little guard in the way so it will take some doing to get it loose without damage.
