Once your Zunder key fob has been delivered to your home, you will see that an information card with a unique, personal and non-transferable activation code is included. You can activate this in the Zunder APP under “Profile>Key fobs”. If you have more than one key fob, you can add all of them here. Enter the code you received (keep this code in case you need it again) and a name that identifies the key fob. You’re all set for your next easier charging session!
