How to take a key off my keyboard?

Hey all,

So I have a 2010 MacBook Pro 15 inch. It's in really good shape in my opinion.. I clean it often and make sure to do things like not to eat over the keyboard, etc. Well, I've noticed that the "v" key is feeling weird. It kind of makes a click sound when I press down on it. I can't tell if anything is under it but it's really annoying. It's gotten to the point where whenever I press the "v" key I kind of lose track of what I was typing in the first place because the key feels weird. It is not sticking down or anything..it just makes a noticeable clicking sound when I press it.

Do any of you know of any tutorial videos on how to maybe remove the key and put it back on? Maybe something is under it by chance? I didn't buy apple care so I highly doubt taking it to the store will help. Since it sounds like a minor problem, maybe they wouldn't mind taking a look at it or maybe even fixing it if it's a really quick fix? Thanks for the help and advice!
