I have two kinds of key problems with my MBP. The first is when pressing a key doesn't enter a character on screen. The second is when pressing a key enters two characters on screen.
Like you, I have found continued use to be a solution for the first problem. To speed up the process you can press down very hard on an affected key. My guess is that this eventually breaks apart any particles that were blocking the key from working.
I haven't found a solution to the second problem though.
