Can I unlock white forest in black 2 on the internet?

Question

I want to play gen 5 and I prefer to black version because it represents the ideal, but I love the forest. I know in black/white 2 they can exchange the key to unlock black city and white forest in each version. My question is do I have to connect to other people face to face to unlock forest in black 2? or can I get the key on the internet(using wifi connection)?

With these games being old I think it's fair to recommend you just use a save editor e.g. PKHeX.

The Key System can only receive new keys from other games over local communication.
