If it is a laptop...It might be difficult....but with a screw driver or a pencil will work.
if you havent done it before i suggest you get it done by someone before you end up killing the keyboardWhat keys do I press on my keyboard?
If it's a normal keyboard, lever it off. If it's a keyboard, often you need to push down and slide it towards you. It might be different for your one though :/Why don't these keys work on my keyboard?
