Go to an auto parts/Harbor Freight and pick up some cheap plastic trim tools, it is easier if you have a variety of sizes.
Start on one side, there are 3 clips on each side, and 2 in the front, I started from the side because if you start on one of the edges you will probably rip the material on the lid.
Get one tool between the top (soft leather like material) and the bottom (hard plastic) and start to pry apart.
once you have the first tool pretty far inside, get another one and do the same thing in another spot on the same side, once you have both going you will now just pull it apart.
2 or 3 screws hold the handle in place, and just reverse the steps to put it back together, just be patient when prying the pieces apart and lining them back up when putting back together.
Might as well put a chrome handle in while you are at it, I have done this in my last two trucks.
