Removing Keyboard Cover

I want to remove the little blue bar on the top of my i5100 that covers the keyboard screws.  I get the general idea (pry with a piece of plastic in the grove on the right side) but I can't seem to get it to pop up.  How much pressure should I use here (I feel like if i flex it too much it's gonna break) and what's the best tool to do this with (preferably things that most people have on hand?)
