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.
