Activating codes before launch?

So I just got one of my halo 5 controllers yesterday and my question is, should I wait till I get the game before putting in the code for the visor, or it doesn’t matter?

What I’ve done is put them in, but kept the codes just in case.

Okay, will probably do the same! Only 20 days left now!

You can activate them now.
