Adding Keys from the Mobile App
If you are the owner of the vehicle, you can pair a new key
using the Tesla mobile app. Adding keys from the Tesla
mobile app can be helpful in the event that you don't have a
working key card or key fob.
NOTE: Pairing a key with the mobile app is supported with
version 4.29.0 of the Tesla mobile app on vehicles with
software versions 2022.40 or higher.
1.
While inside or near the vehicle, open the Tesla mobile
app on your smartphone.
2. In the mobile app, touch Security & Drivers, then touch
Add Key Card.
3. Scan your new key card or key fob on the card reader
located on either wireless phone charger.
NOTE: When adding a key fob, ensure it is at room
temperature. Pairing a key fob that is very cold can be
unsuccessful.
4. When the key is paired successfully, the mobile app
shows a confirmation message. Touch Done in the mobile
app and remove the key card or key fob from the card
reader.
When complete, the key list on the vehicle touchscreen
includes the new key. Touch the associated pencil icon to
customize the name of the key.
Removing Keys
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 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.
Replacing the Key Fob Battery
Under normal use, the accessory key fob 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.
To replace the key fob battery:
1. With the key fob placed button side down on a soft
surface, release the bottom cover, using a small flat-
bladed tool.
2.
Remove the battery by lifting it away from the retaining
clips.
3.
While avoiding touching the battery's flat surfaces, insert
the new battery (type CR2032 ) with the ‘+’ side facing
up.
NOTE: Wipe the battery clean before fitting and avoid
touching the battery's flat surfaces. Finger marks on the
flat surfaces of the battery can reduce battery life.
NOTE: CR2032 batteries can be purchased from any
retailer that sells batteries.
