Instead of a traditional key or key fob, Model 3
supports two types of keys:

•

Key card - communicates with Model 3

using short range radio-frequency
identification (RFID) signals. Allows you to
unlock, drive, and lock Model 3 by tapping

the key card against a Model 3 RFID

transmitter.
Note: The key card is necessary to allow,

or "authenticate", a smart phone to work

with Model 3. It is also considered a

backup key in case your authenticated
smart phone runs out of battery power, or

is lost or stolen.

•

Authenticated smart phone -

communicates with Model 3 using

Bluetooth. Supports automatic locking

and unlocking, driving, as well as multiple

other functions using the Model 3 mobile

app. An authenticated smart phone is the

preferred key because you never need to

remove it from your pocket or purse.

Each type of key is detailed below.

Caution: Remember to bring both your
key card and authenticated smart phone
with you whenever you drive Model 3.

Tesla provides you with two Model 3 key
cards, designed to fit in your wallet. The key
card identifies you as a vehicle owner and
communicates with Model 3 using RFID
transmitters located under the driver
assistance camera on the driver's side door
pillar and behind the cup holders on the
center console. The key card communicates
with the transmitters within a short range of
approximately one or two inches. Keep this in
mind when expecting Model 3 to recognize it.

You will also need your key card to
authenticate a smart phone (see 

 on page

7).

To use the 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 Model 3, you can drive away if you
power up within 15 seconds by pressing the

brake pedal (see 

page 37). If you wait more than 15 seconds

before powering up, your authentication

period expires. To re-authenticate yourself,

place the key card near the hidden RFID

transmitter behind the cup holders on the

center console so that Model 3 can detect it.

Once 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
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 smart phone. 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
