Three Types of Keys
- Phone key - You can set up your personal phone as a "phone key" that communicates with Model 3 using Bluetooth. A phone key supports automatic locking and unlocking.
- Key card - Tesla provides a key card 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 key cards, phone keys, or key fobs. Unlike the phone key and key fob, 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.
- Key fob - The key fob allows you to press buttons to open the front and rear trunks, and unlock, lock, and drive Model 3. The key fob also supports automatic locking and unlocking, if available in your region (see Passive Locking and Unlocking) and can be used as a backup to your phone key. The key fob is an accessory sold separately.
Model 3 supports a total of 19 keys, which can include phone keys, key cards, and up to four key fobs.
Using your phone as a key is a convenient way to access your Model 3. As you approach, your phone's Bluetooth signal is detected and doors unlock when you press a door handle. Likewise, when you exit and walk away with the phone key, doors automatically lock (provided the Walk-Away Door Lock feature is turned on; see Walk-Away Door Lock).
Before you can use a phone to access Model 3, follow these steps to authenticate it:
- Download the Tesla mobile app to your phone.
- Log into the Tesla mobile app using
your Tesla account username and password.NoteYou must remain logged in to your Tesla account to use your phone to access Model 3.NoteIf multiple vehicles are linked to your Tesla account, you must ensure that the vehicle you want the mobile app to access is currently selected on the mobile app.
NoteModel 3 communicates with your phone using Bluetooth. Keep in mind that your phone must have enough battery power to run Bluetooth and that many phones disable Bluetooth when the battery is low.
- Your phone's general Bluetooth settings are enabled.
- Bluetooth is enabled within your phone's settings for the Tesla mobile app. For example, on your phone, navigate to Settings, choose the Tesla mobile app, and ensure the Bluetooth setting is turned on.
- Access to your location is enabled. Open the Tesla mobile app in your phone's settings and select . For the best experience, keep the mobile app running in the background.
- Allow Mobile Access is enabled on the vehicle touchscreen ( ).
- While sitting inside the vehicle with a key card handy, open the Tesla mobile app and touch Set Up Phone Key on the main screen, or navigate to . Follow the prompts on the mobile app and vehicle touchscreen to set up your phone key.
To view a list of keys that can currently access Model 3, or to remove a phone key, touch (see Managing Keys).
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 Pairing a Bluetooth Phone).
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 behind the cup holders on the center console. When your key card is detected, your two minute authentication period restarts.
If you have purchased the key fob accessory (available for purchase from Tesla stores or online at http://www.tesla.com/shop), you can quickly familiarize yourself with this key by thinking of it as a miniature version of Model 3, with the Tesla badge representing the front. The key has three buttons that feel like softer areas on the surface.
- Front trunk - Double-click to unlatch the front trunk.
- Lock/Unlock All - Single-click to lock doors and trunks (all doors and trunks must be closed). Double-click to unlock doors and trunks.
- Rear trunk - Double-click to unlatch the rear trunk. Hold down for one to two seconds to open the charge port door.
Once inside, power up Model 3 by pressing the brake pedal within two minutes of pressing the unlock button on the key fob (see Starting and Powering Off). If you wait longer than two minutes, you must press the unlock button again, or place the key fob near the card reader located behind the cup holders on the center console. When your key fob is detected, the two minute authentication period restarts.
When approaching or leaving Model 3 carrying the key fob, you do not need to point the key fob at Model 3 as you press a button, but you must be within operating range.
Radio equipment on a similar frequency can affect the key. If this happens, move the key at least 30 cm away from other electronic devices (phones, laptops, etc.).
In the event that the key fob's battery is dead, you can still use it to drive the vehicle by scanning the key fob on the card reader located on the driver's side door pillar (like the key card).
Instructions for changing the battery are provided in Replacing the Key Fob Battery.
Passive Locking and Unlocking
Due to market region or vehicle configuration, passive locking and unlocking may not be available for your vehicle.
Locking and unlocking Model 3 with your key fob is conveniently hands-free. Although you must be carrying a paired key fob, there is no need to use it. Model 3 has sensors around the vehicle that can recognize the presence of a key fob within a range of approximately two meters. Therefore, you can keep your key fob in your pocket or purse and simply pull on the door handle to unlock. When carrying your key fob with you, you can also open the trunk without having to use the key by pressing the rear trunk's exterior door handle. If Walk-Away Door Lock is enabled, Model 3 automatically locks when you exit and the key fob is no longer in range (see Walk-Away Door Lock). Passive locking and unlocking is automatically enabled when you pair your key fob to Model 3.
Although you can use the same key fob with multiple vehicles, it can only be paired to one vehicle at a time. To activate a paired key fob to a different vehicle, touch the flat side onto the driver's side door pillar and click any button on the key fob to confirm.
Replacing the Key Fob Battery
Under normal use, the accessory key fob (available at https://shop.tesla.com) has a battery that lasts for up to one year, depending on key fob version and selected vehicle settings. When the battery is low, a message displays on the touchscreen.
