My shift key comes out of my toshiba laptop, and freaked that it came out and now thought I was going to get the livings beatings out of me. So I researched on the internet on how to fix keyboard buttons. I REALLY recommend this website. http://www.laptoprepair101.com/laptop/2007/03/20/key-fell-off-keyboard/comment-page-110/#comment-133080
It helped me with all my keyboard button problems.
Good Luck. :)
