Types of Keys
- Phone key - You can set up your personal phone as a "phone key" that communicate with Model 3 using Bluetooth. A phone key supports automatic locking and unlocking.
- Key card - Tesla provides two key cards that communicates with Model 3 using short range radio-frequency identification (RFID) signals. The key card is used to "authenticate" phone keys to work with Model 3 and to add or remove other keys. Unlike the phone key, the key card does not support automatic locking and unlocking. In situations where your phone key has a dead battery, or is lost or stolen, use your key card to unlock, drive, and lock Model 3.
Model 3 supports a total of 19 keys, which can include phone keys and key cards.

Model 3 can connect to three phone keys simultaneously. 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.
Once a phone has been authenticated, it no longer requires an internet connection to be used as a phone key for Model 3. 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 Bluetooth).
Some smartphones with NFC capability can be used to lock/unlock your vehicle, just like using a key card. Ensure the Tesla mobile app is correctly paired to your vehicle and enable the NFC function on your phone. Once enabled, simply hold the phone to the driver's side door pillar to lock or unlock the door. Refer to your smartphone's instructions for specific information on how to do this.
Tesla provides you with two Model 3 key cards, designed to fit in your wallet.
Once inside, power up Model 3 by pressing the brake pedal within two minutes of scanning the key card (see Starting and Powering Off). If you wait longer than two minutes, you must re-authenticate by placing the key card near the card reader located in the wireless phone charger on the center console. When your key card is detected, your two minute authentication period restarts.
