For TM6 there is no need for this since the Cook-Key® has been eliminated. The TM6 has an integrated WiFi module that allows easier, more efficient, seamingless communication with the internet.
For TM5 registering your Cook-key® in the Thermomix® Cookidoo® recipe portal is no problem. After signing in to Cookidoo®, you activate the Cook-key® in your user profile using its serial number.
Just log in to your Cookidoo® -> account -> My Devices -> add device -> Cook-Key® and enter the Cook-Key® identification nummer.
Every serial number is unique. The connection between the Thermomix® recipe portal and the Cook-key® will only work by entering the correct serial number.
Alternatively, you can also activate your Cook-key® via the iOS or Android apps.
Important: A cook-key® may be activated on only one device at a time. If you want to use the cook-key® on another device, the Cook-Key® must be deactivated from the previous Cookidoo® account. www.cookidoo.com ->account -> My Devices -> deactivate the Cook-Key®.
