3. While avoiding touching the battery's flat

align the tabs on the cover with the
corresponding slots on the key fob, then

until it snaps into place.
Attaching a Lanyard
To attach a lanyard, release the bottom cover
as described above. Place the lanyard over the
pin located between the slots on the widest
side of the key fob. Re-align the cover and
snap into place.
Managing Keys
To display a key list that shows all keys
(phones, key cards, and key fobs) that can
access your Model 3, touch Controls > Locks.
An icon displays next to each key to indicate
whether the key is a phone, key card or key
fob. Use this list to view, add or delete keys. To
add or delete keys, you will need a key card
that has already been authenticated.
To add a new key, touch +, then follow the
onscreen prompts. When complete, the key
list displays the new key. If the key is a phone,
the key list displays the name of the phone. If
the key is a card or key fob, you can customize
its name by touching the associated pencil
icon.
Note: Key fob pairing should be performed
when the key fob is at room temperature.
Pairing may be unsuccessful if the key fob is
cold.
Note: To add a phone, the phone must be
running the Tesla mobile app and connected
to a Tesla account, and Bluetooth must be
enabled. You can also use the mobile app to
add a phone key. For details, see
Authenticated Phone on page 7).
Note: You can use the same key for more than
one Model 3. 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 3, any other Model 3 to which the key
card or key fob is authenticated also displays
the customized name.
When you no longer want a key to access your
Model 3 (for example, you lost your phone or
key card, etc.), touch its associated trash icon
on the key list, then follow the onscreen
prompts to confirm the deletion. When
complete, the key list no longer includes the
deleted key.
Note: Model 3 requires at least one
authenticated key card at all times. If only one
key card is included on the key list, this key
cannot be deleted.
Note: Model 3 supports up to 19 keys. When
this limit is reached, you must delete a key
before adding a new one.
