Keys
To drive the vehicle, scan the key fob on the
phone charger.
1. Place it at the top of the left phone
charger, against the center divider.
2. Point the front of the key fob to the left.
3. Swipe downwards.
Instructions for changing the battery are
provided in Replacing the Key Fob Battery on
page 12.
NOTE: You can use the same key fob with
multiple Model X vehicles provided you
authenticate it (see Managing Keys on page
14). However, key fob works with only one
Model X at a time. Therefore, to use a key fob
for a different Model X, touch its flat side
against the card reader on the driver's side
door pillar.

NOTE: Model X supports up to four different
key fobs.
CAUTION: Protect the key from
impact, high temperatures, and
damage from liquids. Avoid contact
with solvents, waxes, and abrasive
cleaners.
Passive Locking and Unlocking
Locking and unlocking Model X 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 X has sensors around
the vehicle that can recognize the presence of
a key fob within a range of approximately six
feet (two meters). Therefore, you can keep
your key fob in your pocket or purse and
press the door handle to unlock and extend
the handle. When carrying your key fob with
you, you can also open the trunk without
having to use the key by pressing the
liftgate's exterior switch. If Walk-Away Door
Lock is enabled, Model X automatically locks
when you exit and the key fob is no longer in
range (see Walk-Away Door Lock on page
19). Passive locking and unlocking is
automatically enabled when you pair your key
fob to Model X.
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.
NOTE: For increased security, passive locking
and unlocking disables after being stationary
for five minutes while within vehicle range
when the vehicle is not in use (for example,
you are standing outside your vehicle). In this
situation, you must shake or press a button on
the key fob to re-enable passive locking and
unlocking.
Replacing the Key Fob Battery
Under normal use, the 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.
