Now that you've gotten this far, I hope you are ready for the bad part. The select button is the one button that is not easily removeable. I have never replaced one but it is attached to the circuit board whereas the rest of the buttons are not. At least with the above steps you can take a look yourself and see if it is worth trying to fix. At the end of the day if you decide it is not worth it, perhaps an upgrade will be the best course of action.
