Must be you. You get the keys by completing maps 100%, so depending on when you started to play, you could’ve gotten some already.
If not, quickest would be completing the hometowns (all available through LA gates) and hoping for a few keys.
That said, I made a few MK chests but was unlucky with all of them. So, it’s not like you definately miss out on anything if you don’t get them.
I’ve opened over 20 chests and haven’t got anything from it. I recommend to do Mad King event instead and when the dungeon is closed you can farm keys by leveling up human warriors (commoners) and doing personal story quest at lvl 10 (You only have to do story quest and nothing else). If do skip cutscenes you can make a run in about 25 minutes but it depends how you value your time, you can also buy them for 1-2$ each.
The easiest way to get keys is probably to convert your gold and silver into gems then buy keys from the gem shop. Converting a little over 4 gold pieces would get you 5 keys. After that, you probably can convert some of the consumables from the chests to make madking chests.
