NOTE: You can use the same key fob with multiple
Model Y vehicles provided you authenticate it (see
Managing Keys on page 10). However, key fob works
with only one Model Y at a time. Therefore, to use a key
fob for a different Model Y, touch its flat side against the
card reader on the driver's side door pillar.
NOTE: Model Y 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 Y 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 Y 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 simply pull on the door
handle to unlock. 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 door handle. If
Walk-Away Door Lock is enabled, Model Y automatically
locks when you exit and the key fob is no longer in range
(see Walk-Away Door Lock on page
locking and unlocking is automatically enabled when
you pair your key fob to Model Y.
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.
