Depends on which keys you mean.
If you mean the collection keys used to open the chests in Snowhill, Briarwood, Blackspore, and Sanctuary then those are found in "Rare Robgoblin junk piles."
Only the rare ones, However you can buy them from other players as well, (normally around 1,000 coins each). One key, however, from the Snowhill collection is from a quest.
If you want keys on free realms, then you have to look for Rare Robgoblin junk piles..GOOD LUCK!!! XD
You need all the keys to that one collection. Some collections have 5 keys, or 8 keys.
you get them from keys so btw the keys are in sactary:)
Add them into the trade window.
there in robgoblin junk piles
You have to hold shift and use your arrow keys at the same time to slow walk in Free Realms.
rare robgoblin junk
collect robgoblin junkpiles and get keys
You can either buy them from a player, or get them from collecting all the useful keys, and opening the chest in Blackspore.
Open the Ayani Chest, it's actually pretty easy, get all the fancy keys i think.
They are the items that help you open the treasure chests in free reams.
To slow walk in free realms hit the shift key and then use the arrow keys to move. But yu have to keep hold on the shift key.
