Replacing laptop keyboard?

[fresh_and_flii]

I turn my back for one second to look at something and when I turn back around my friends cat was laying on my keyboard on my laptop. I go to get her off and she pulls a key off and I accidentally pulled one out myself. I go to fix the metal hooks that hold the keys together and three of them broke. Is it possible just to fix the side of the keyboard that the keys broke off from? Which was on the left side where the num lock is.
