After purchase, you will receive an SMS with a link to the “My Camping Key” app and an SMS with an activation code. You can now immediately start using all the benefits included on the card.
By the way, there is also a free version called Camping ID. You won’t get any discounts, benefits, camping insurance or the camping catalogue sent to you, but at least you can check in quickly and easily and you won’t have to show any ID.

Do you already have an active CKE? Then it will probably go out sometime during the season. You can already extend the validity by 12 extra months via the above link, so you know that your CKE will last the whole season until next year and that you won’t suddenly find yourself at the reception with an expired Camping Key Europe, which of course means extra waiting time.
