Presumably the codes would have been put inside the box during production, so Larian would need to open the games to give people codes before shipping (unless they have some kind of barcode system where they can look up the codes for each copy, or something).

You mean assuming it is done early enough? Larian will probably use as much time as they have to get as many updates as possible in the initial release.
