If you ordered digital through origin, you will get your retail key starting the 16th.
If you ordered digital through anywhere else, they should tell you when you get your retail key.
If you ordered a physical copy, and have said physical copy, your retail key is in, on, or around the box
If you ordered a physical copy, and do not have said physical copy, your retail key is in, on, or around said box that you are not in possesions of.
NONE of this has any bearing on your Early Access, any key that you have received up until now, that hasn't come from a box is 99% likely to be a pre-order kay and not a RETAIL key
