Using your phone to access your Model Y is a convenient option. Your phone's Bluetooth connection is recognised as you approach, and doors unlock when you press a door handle. Similarly, when you exit and walk away with your phone, the doors automatically lock (if the Walk-Away Door Lock option is enabled).
Follow these procedures to authorise your phone before using it to access your Model Y:
The mobile app will indicate that your phone has been successfully authenticated when Model Y identifies your key card. Touch Done.
Touch Controls > Locks to display a list of keys that can currently access Model Y, or to delete a phone (see Managing Keys).
Note: Once you've authenticated your phone, you can use it as a key to access your Model Y. You must pair and connect to the phone using the Bluetooth settings in order to use it hands-free, access your phone's contacts, play media from it, and so on.
Note: The Model Y can connect to three phones at the same time. If you want to use or authenticate a different phone, move the other connected phone(s) out of range or switch off its Bluetooth setting if more than one phone is identified.
Note: Once a phone is authorised, it no longer needs to be connected to the internet in order to communicate with Model Y. Bluetooth is used to communicate with the Model Y via authenticated phones.
Note: While Bluetooth can communicate across distances of up to 30 feet (9 metres), performance can vary depending on the phone you're using, ambient interference, and other factors.
Note: If your Tesla Account has numerous vehicles attached to it, you must first switch the mobile app to the vehicle you want to enter before you may use the phone as a key.
