Maybe the time for the keys to reunite hasn't come yet, if you remember the chapter 282, Yukino spoke about a legend according which the keys will open the gateway that will change the world, everybody thought about Eclipe, but the more I think the more I believe this gateway isn't Eclipse but is the only thing which can stop Zeref before he destroys the whole world, maybe something created 400 years ago to stop Zeref if he become too dangerous
