Tesla Model 3 Owner's Manual page 7

To use a key card to unlock Model 3, briefly
tap it against the hidden RFID transmitter
located below the driver assistance camera on
the driver's side door pillar. When Model 3
detects the key card, exterior lights flash
twice, mirrors unfold (if Mirror Auto Fold is
on), and doors unlock.
Once inside, you can drive away if you power
up Model 3 by pressing the brake pedal (see
Starting and Powering Off
within 15 seconds of scanning the key card
against the transmitter. If you wait more than
15 seconds, you must re-authenticate yourself
by placing the key card near the RFID
transmitter located behind the cup holders on
the center console. When your key card is
detected, your 15-second authentication
period restarts.
Note: It is important that you position the key
card within an inch or two of an RFID
transmitter to allow Model 3 to read it. You
may need to physically touch the center
console or driver's side door pillar with the key
card for the RFID transmitter to detect it, and

on page 37)
you may need to hold it against the
transmitter for one or two seconds.
Note: The Walk Away Lock and Walk Up
Unlock features operate only when using an
authenticated smartphone. When you walk up
to/away from Model 3 carrying only your key
card, Model 3 does not automatically unlock/
lock even if these features are turned on (see
Walk Away Lock on page 10 and
Unlock on page 10).
Caution: It is a good idea to always carry
your key card with you in your purse or
wallet to use as a backup in case your
authenticated smartphone has a dead
battery, or is lost or stolen.
Forgetting an Authenticated
Smartphone
In situations where you no longer want your
smartphone to access Model 3 (for example,
your smartphone is lost or stolen), contact
Tesla support to disable the Tesla mobile app.
If you have access to your smartphone and
you no longer want the smartphone to be
used as a key to your Model 3, simply delete
the Tesla mobile app from the smartphone
using the same method you use to delete any
other app. Once the mobile app is removed,
the smartphone can no longer communicate
with Model 3.
Mobile App
In addition to allowing you to use your
smartphone as your Model 3 key, the mobile
app allows you to:
• Lock or unlock Model 3 from afar.
• Check charging progress and receive
notifications when charging has started,
has been interrupted, or is complete.
• Heat or cool Model 3 before driving (even
if it's in a garage).
• Locate Model 3 with directions, or track its
movement across a map.
• Flash the exterior lights or honk the horn
to find Model 3 when parked.
• Start Model 3 remotely.
• Park or unpark Model 3 using Summon
