Of course! Don't even have the keyboard actually attached, have some guy in the gallery push the buttons too... Add those sound effects in post-production as well. No wonder there are no themes that enable your computer to beep and chirp like in the movies.

Alternatively have the keyboard set up as one big "anykey" to advance the animation. The advantage of this being that keyboard strikes would be synced with screen updates, if there is ever a shot where you can see both the fingers and the screen (which is typically avoided, but still).
