The keyboard on my macbook died about a year back, i was looking for a way to fix it. I went a while with an external keyboard but this was too cumbersome so i looked up how to fix it and chose to fix it myself
The repair was fairly easy, just a bit more difficult than installing RAM but needed to be done.
Be careful when removing screws so you don't mix them up. Also you need to listen for the click of he connector before putting the system back together.
