The Cook-Key® is an accessory that enables TM5 users to send recipes from Cookidoo®, the online cooking platform, directly to the display of the TM5 via wi-fi. It attaches to the interface on the side of the Thermomix TM5. It is available for purchase from a Consultant or in the online e-shop at shop.thermomix.com. It is not necessary for the TM6, as Cookidoo® is fully integrated.
