Lock • After unlocking the vehicle via NFC, you can still lock it using other methods (e.g. your smart key fob or emergency key). We recommend carrying your smart key fob or phone with you. • Please keep your NFC card safe. Protect it from impact, bending, high temperatures, strong vibration, and damage from liquids. • You cannot use the NFC feature during vehicle updates. Please carry the smart key fob with you to unlock the vehicle. • When unlocking or locking the vehicle via NFC, please log into the NIO app and redownload the NFC key if you are unable to obtain an authenticated NFC key. If an authenticated NFC key is not detected, please ensure that the vehicle matches the NFC account.
Then reopen the NFC app and unlock the mobile phone screen to unlock or lock the vehicle again. If NFC still doesn't work, please contact NIO. 13
