Al P Ward , you can pop those keys of the individual keys, and see if the switches still work, if you depress those. If they do not work, you will have to replace the keyboard. Check this [http://www.youtube.com/watch?v=TvXPCG8PNBY|video] for a tutorial on how to pop them off, and on [http://laptoppartstore.weebly.com/replace--remove-toshiba-satellite-l300-l305-keyboard.html|here] how to take the keyboard off. Hope this helps, good luck.
