Could you de-copyright things in this manner? Say I make locks that only open when they hear music from Disney's lion king. Are you allowed to play that song to open the lock, even without opening it? Does it matter if it was disney or me that made the lock? Silly example of course, can't think of any better. Feel free to substitute your own.
