Actually, I think you can find hardmode chests in a softmode dungeon. That's how I've been getting mine, since most of my worlds were either put into hardmode before 1.2 or I just never bothered. I also got the Corruption, Hallowed, and Crimson keys in a few minutes of random farming each, guess I just have dumb luck. :P
