I noticed a few things which seem to make them appear. After you start collecting keys and the more you open the board, making specials which clear space, but mostly I think it's just the more you match, the more they appear. I got into a rhythm my passing try(am waiting for it to come out on iPad to compare to PC in my post)....after I'd collected all the keys whenever I matched one a new one would appear, sometimes even more than one on the board. But they can also get stuck in the same section the initial unlocked keys appear in & I didn't always even notice them at first. To get those you either have to be lucky to have the same colors around them or move candies around on the main board to bring them down. But yeah I think it's mostly the more you match, the more you get.
