Stuck

So you can't unlock the door? 1. Use your stick to knock down the item in the locker room 2. Decipher the item's meaning. Get out of the locker room and read the blue poster for a hint. 3. You'll know what to do with the Fire of Hades msg once you unlock the door

I have NO idea what this means. And I can't decipher the item's meaning.

Your NNID is kearnodalyetsutriax. Odds only, evens out.

So it says:To Solve Memo B Shift 1 Key To The Left On QWERTY Keyboard. Still a little confused there.

The keypad for entering public keys and passcodes is also QWERTY right? So if a code says "ESYRT", it means "WATER" since you have to read one key to the left.

???

What do they mean by "key"?

OHHHHH Nvm I get it now Thanks!
