I've opened a couple, not hard. I used visegrips to get the 4 screws out and replaced with stainless steel button heads. Then you need a screw driver or two and an exato knife. Use the screw drivers to start a gap to get the exato in to start cutting the silicon bead seal. As you work your way around cutting as you go, it will open more and more and get easier and easier. You can easily permanently bend your cover, so just bend it to flex it, not permanently deform it. You'll get a feel for it quick. Good luck.
