Collecting the Mystery Keys

This isn’t focusing on what’s inside the box, but gathering the keys. As we all know Castle Mania (or Mane-ia according to a screenshot) airs next Saturday. I have a hunch that they might find their first key there.
 
Another thing to note, the keyholes are oddly shaped, hmmmm. What do you guys think?

Each keyhole is different. The keys are actually physical, too. That’s different.

Assuming the season finale is a two-parter, they have 22-23 episodes to find the keys. Which means they have to find one in every 3-4 episodes. The first key will be found in 4x03 or 4x04. Six keys, six ponies. They will find their respective key in their key episode.
 
If >>479410 is not just a Dash’s self-insert fanfic, my hope (wish) is that Dash finds her key during her epic adventure with Daring Do.
 
Maybe one of the keys is in the comic book?

You should make the title “collecting the mystery keys” or something then

They don’t look for the keys at all during the season, and in the final they buy them from the Mann Co. store. (jk)

Maybe the keys are hidden elsewhere?
 
Maybe they don’t need to be manifested, just found.

“My treasure? If you want it, you can have it.  
Seek it out! I left everything in my life at that place!”  
And so did the great age of piracy begun

All six keys in EP 25/26!

That makes so much sense, it’s kind of scary.

@Background Pony  
Probably this.

It’ll be like the special stages in Sonic. And Tails screws them over every time.

There’s a massive assumption going on here that the keys will be slowly gathered over the course of the season. That might not happen.
 
I might go that way, but don’t assume that now and get disappointed. It’s entirely possible this arc won’t really resume until the end of the season.
 
Keep in mind that even if that is the case, that’s 6 keys over 20 something episodes. They won’t find one each bloody week.

I had this crazy idea of half the keys this season, the next three being saved for S5.

Here’s a thought, maybe they’ll make a movie for all the keys, like some sort of adventure/questing type movie, It would be reasonable to expect another FiM movie at some point, anyway.

I’m guessing the keys are not located in some kind of ruin or old temple but instead in each of the Mane6’s “hearts” and in one of each chars “Key” Ep. once they have done something meaningful or discovered something about themselves their key will appear to them.
 
Also guessing whatever is inside the box is what gives them their “Rainbow Powers”.

Get them by defeating a boss?

They’ll probably have to trade two refined for them.

@Trickquestion  
Keys go for way more than that.

Buy them from Gaben.

A part of me fears they’ll just rush the plot like what happened with Jake Long, though after watching Castle-Mania, I have some faith in the show restored.

It’s in the last 3 episodes of season 4

If you watch the entire season and then the last 2 episodes u learn they get there keys in every episode after twilight becomes a princess and gets the box it explains this in episode 25 and the box is opened in episode 26 along with twilight finding her key
