Needing some help with this one. After looking back I can identify the matching key numbers:

24 15 6 27 12 28

But that is wrong when I enter in those numbers.
The key answers themselves are no help especially with the answer to key 28 being that long sequence of numbers

Any help?

Never mind… I figured it out.
Ahah! The symbols!
