How to use Key Fob with Model 3

If you have purchased the key fob accessory (available
for purchase from Tesla stores or online), you can quickly
familiarize yourself with this key by thinking of it as a miniature
version of Model 3, with the Tesla badge representing
the front. The key has three buttons that feel like softer
areas on the surface.

  1. Front trunk – Double-click to open the front trunk.
  2. Lock/Unlock All – Single-click to lock doors and
    trunks (all doors and trunks must be closed).
    Double-click to unlock doors and trunks.
  3. Rear trunk – Double-click to open the rear trunk. Hold down
    for one to two seconds to open the charge port door.

Once inside, power up Model 3 by pressing the brake
pedal within two minutes of pressing the unlock button
on the key fob. If you wait longer than two minutes, you must
press the unlock button again, or place the key fob near
the card reader located behind the cup holders on the
center console. When your key fob is detected, the two
minute authentication period restarts.

When approaching or leaving Model 3 carrying the key
fob, you do not need to point the key fob at Model 3 as
you press a button, but you must be within operating

Radio equipment on a similar frequency can affect the
key. If this happens, move the key at least one foot
(30 cm) away from other electronic devices (phone,
laptop, etc.).

If the key fob does not work (for example, its battery is
dead), you can touch its flat side against the card
reader on the driver’s side door pillar (like the key card).

NOTE: You can use the same key fob with multiple
Model 3 vehicles provided you authenticate it (see
Managing Keys on page 11). However, key fob works
with only one Model 3 at a time. Therefore, to use a key
fob for a different Model 3, touch its flat side against
the card reader on the driver’s side door pillar.

NOTE: Model 3 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

Passive Key Fob

Due market region or vehicle configuration, Passive Key
Fob may not be available for your vehicle.

Locking and unlocking Model 3 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 3 has sensors around the vehicle that can
recognize the presence of a key fob within a range of
approximately three feet (one meter). 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
trunk’s exterior door handle. If Walk-Away Lock is on,
your vehicle automatically locks when you exit and
senses that the key fob is no longer in range, Passive
key fob is automatically enabled when you pair your
key fob to your vehicle.

The key fob can only be paired to one vehicle at a time.
If you want your key fob to passively lock and unlock
for a different vehicle, touch the flat side of the key fob
onto the driver’s side door pillar or center console card
reader. You only need to do this once to pair it to your
desired vehicle. You must pair your key fob every time
you use it with a different vehicle.

NOTE: Only key fobs with the TESLA logo printed on
the flat side have the passive locking and unlocking
functionality. Key fobs with the MODEL 3 logo printed
on the flat side cannot passively lock and unlock your

NOTE: For increased security, your key fob disables
itself after five minutes of being stationary while in
range but the vehicle is not in use. The vehicle will not
lock or unlock passively when this occurs. Shake or
press a button on your key fob to wake it up.

Replacing the Key Fob Battery
Under normal use, the accessory key fob has a battery
that lasts for up to five years, depending on key fob
version and selected vehicle settings.

  1. With the key fob placed button side down on a soft
    surface, release the bottom cover.
  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: CR2032 batteries can be purchased through
    online retailers, local supermarkets, and drug stores.

  4. Holding the bottom cover at an angle, align the tabs on
    the cover with the corresponding slots on the key fob, then
    press the cover firmly onto the key fob until it snaps into place.
  5. Test that the key fob works by unlocking and locking your vehicle.
