How to Add and Remove Keys on Model 3

Three Types of Keys

Model Y supports three types of keys:

Phone key – You can set up your personal phone as a “phone key” that communicates with Model Y using Bluetooth. A phone key supports automatic locking and unlocking.

Key card – Tesla provides a key card that communicates with Model Y using short range radio-frequency identification (RFID) signals. 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. 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 Y.

Key fob – The key fob allows you to press buttons to open the front and rear trunks, and unlock, lock, and drive Model Y. The key fob also supports automatic locking and unlocking, if available in your region and can be used as a backup to your phone key. The key fob is an accessory sold separately.

CAUTION: Remember to bring a key with you when you drive. Although you can drive Model Y away from its key, you will be unable to power it back on after it powers off.

Managing Keys

To display a list of all keys (phone keys, key cards, and key fobs) that can access your Model Y, touch Controls > Locks. An icon displays next to each key to indicate whether the key is a phone key, key card, or key fob. Use this list to manage keys that have access to your Model Y.

Model Y supports up to 19 keys. When you reach this limit, you must delete a key before adding a new one.

NOTE: You can use the same key for more than one Model Y. This prevents you from having to deal with multiple keys when you switch vehicles. If you customize the name of an authenticated key card or key fob on one Model Y (by touching the pencil icon), any other Model Y to which the key card or key fob is authenticated also displays the changed name.

Adding and Removing Keys

To add a new key card or key fob:

NOTE: When adding a key fob, ensure it is at room temperature. Pairing a key fob that is very cold can be unsuccessful.

  1. On the touchscreen, touch Controls > Locks then touch + in the Keys section.
  2. Scan your new key card or key fob on the card reader located behind the cup holders on the top of the center console. After the new key card or key fob is recognized, remove it from the card reader.
  3. Scan a key card or key fob that has already been paired to the vehicle to confirm new key pairing.
  4. When complete, the key list includes the new key. Touch the associated pencil icon to customize the name of the key.

To add a new phone key:

NOTE: You must enable Bluetooth on the phone and have the Tesla mobile app installed and connected to your Tesla account.

  1. While sitting in Model Y, open the Tesla mobile app (if you have multiple Tesla vehicles, select the appropriate vehicle), then touch Phone Key > Start.
  2. Scan an authenticated key card or key fob on the card reader located behind the cup holders on the top of the center console.
  3. When the mobile app notifies you that pairing was successful, touch Done. The key list on the touchscreen (touch Controls > Locks) includes the newly authenticated phone key. The name of the phone key is determined by the name used in the phone’s settings.

Removing a key:

When you no longer want a key to access Model Y (for example, you lost your phone or key card, etc.), follow these steps to remove it.

  1. On the touchscreen, touch Controls > Locks.
  2. In the key list, find the key that you would like to delete and touch its associated trash icon.
  3. When prompted, scan an authenticated key card or key fob on the card reader to confirm the deletion. When complete, the key list no longer includes the deleted key.

    NOTE: Model Y requires at least one authenticated key card or key fob at all times. If only one key card remains on the key list, you cannot delete it.

How to use phone as a key with Model Y

Phone key

You can set up your personal phone as a “phone key” that communicates with Model Y using Bluetooth. A phone key supports automatic locking and unlocking.

Using your phone as a key is a convenient way to access your Model Y. 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).

Before you can use a phone to access Model Y, follow these steps to authenticate it:

  1. Download the Tesla mobile app to your phone.
  2. Log into the Tesla mobile app using your Tesla Account user name and password.
    NOTE: You must remain logged in to your Tesla Account to use your phone to access Model Y.
  3. Ensure that your phone’s Bluetooth settings are turned on.

You must have your phone’s Bluetooth setting turned on AND you must also ensure that Bluetooth is turned on within your phone’s global 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 enabled.

NOTE: Model Y communicates with your phone using Bluetooth. To authenticate your phone to use it as a key, the phone must be powered on and Bluetooth must be enabled. 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.

  1. Ensure location access is enabled by viewing the mobile app in your phone’s settings and selecting Location > Always. For the best experience, keep the mobile app running in the background.
  2. Ensure that Allow Mobile Access is enabled (Controls > Safety & Security > Allow Mobile Access).
  3. In the Tesla mobile app, touch PHONE KEY then touch START to search for your Model Y.
    When your Model Y is detected, the mobile app asks you to tap your key card.
  4. Tap the key card against the Model Y card reader on the door pillar or center console.

When Model Y detects your key card, the mobile app confirms that your phone key has been successfully authenticated. Touch DONE.

If the key card is not successfully scanned within approximately thirty seconds, the mobile app displays an error message. To retry, touch PHONE KEY again in the Tesla mobile app.

To view a list of keys that can currently access Model Y, or to remove a phone key, touch Controls > Locks

Authenticating your phone allows you to use it as a key to access Model Y.

Model Y can connect to three phone keys simultaneously. Therefore, if more than one phone key is detected and you want to use, or authenticate, a different phone, move the other connected phone key(s) out of range or turn off its Bluetooth setting.

Unlike the mobile app, once a phone has been authenticated, it no longer requires an internet connection to be used as a phone key for Model Y. Authenticated phone keys communicate with Model Y using 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.

NOTE: Although Bluetooth typically communicates over distances of up to approximately 30 feet (9 meters), performance can vary based on the phone you are using, environmental interference, etc.

NOTE: If 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.

How to add and remove keys on Model 3
