Pokemon B/W 2 Save File Editing Question.

[the4got10-1]

Hi all.

I am trying to get some White 2 exclusive keys on my Black 2 save file. From what I understand, they are:

- Easy Mode Key (as opposed to Hard Mode)

- Iceberg Key (as opposed to Iron Key)

- Treehollow Key (as opposed to Tower Key)

As seen in the picture attached though, the third option has apparently been combined into a "City Key" on PKHex. I assume checking this option will unlock both keys at once. Will this interfere with the game's event flags when I reach the point in the Black Tower where I am supposed to obtain the Tower Key?
