There is no need to take the topcase off, since the keyboard isn't accesible from underneath. If its just a cleaning job you can pop off the keycap and try your luck. Video showing the process [http://www.youtube.com/watch?v=2Kg6EfuR-6Y|here]. Mostly dead keys are the result of a spillage and require the exchange of the whole topcase.
