TYPES OF KEYS BLUETOOTH
However, to use the phone hands-free, access your phone's contacts, play media from it, etc., you must also pair it and connect it as a Bluetooth device (see Pairing a Bluetooth Phone). Once a phone has been authenticated, it no longer requires an internet connection to be used as a phone key for Model Y. Therefore, if more than three phone keys are detected and you want to authenticate or pair a different phone, move the other connected phone key(s) out of range or turn off its Bluetooth setting. Model Y can connect to three phone keys simultaneously. To view a list of keys that can currently access Model Y, or to remove a phone key, touch Controls > Locks (see Managing Keys). Follow the prompts on the mobile app and vehicle touchscreen to set up your phone key.

The key card is used to "authenticate" phone keys to work with Model Y and to add or remove other key cards, phone keys, or key fobs.
