Haha good for you, for the key you need to go to L2-9 to kill the Soul Ruler (be sure it's not Soul Hunter), during the process you just keep running to destroy the machine, don't bother stepping on the trap, just stand still when the ice block come, and stay down til it's over you.
the chance of a key box dropped from Soul Ruler is about 3/5 rate, good luck! =]
