I got stuck at step 5 in this tutorial

I saw that there are 2 gold color mounting clips, but I couldn't pull it hard enough to remove it. It looked kind of lopsided too (one clip is higher than the other side). Do you guys just remove it with your finger? How hard do I have to yank it? Will I damage anything if I just get some wire hanger and yank it out? Thanks...
