Remove 3 large screws and there should be another small one by the lock mechanism.
I recommend putting duct tape ( one that does not leave a residue) on all corners and edges just in case.
The panel is held on by clips on the bottom and sides. You just have to pull it out starting at the bottom. It is not too hard. Once you have the bottoms and sides clear you have to push up hard from the bottom and it is off.
You will have a lock cable and some wires dangling but they are easy to take off.
It might be useful to have another hand the first time.
Take your time putting it back on and lining up the top of the panel.
Try not to break the clips putting it back on. I broke a couple and when I went to the dealer to get some they just gave me a handful - it seems they must break quite a few as well.
