Where did you read that it has to be claimed by Monday (which is the 15th)? As far as we know there is no such limit on codes, Bethesda has informed us that we will be able to offer the Early Access (which is why we added it to the store page) for May 22nd. Keys are still to be delivered by them, as soon as we get the greenlight to send them out we'll do that - which hopefully will not be too far away.

I know it's frustrating waiting for keys, but we can't send them out any sooner sadly. Don't worry, you will get your Early Access.
