Two number keys do not work on my toshiba laptop. I have removed them and they do not seem dirty. Is ther something I can do to fix it?
If giving a good cleaning doesn't help it, you may wish to simply jump to buying a replacement keyboard.
My old laptop had a similar problem, the E key stopped functioning, and for just $6 I picked up a new one off ebay, and it was solved. (Make sure it's from the same make/model of laptop!)
