2021 MAZDA MODEL CX-5 key

Modification and Add-OnEquipment
Mazda cannot guarantee the immobilizer
and the theft-deterrent systems' operation
if the system has been modified or if any
add-on equipment has been installed.
CAUTION
To avoid damage to the vehicle, do not
modify the system or install any add-on
equipment to the immobilizer and the
theft-deterrent systems or the vehicle.
Immobilizer System
The immobilizer system allows the engine
to start only with a key the system
recognizes.

If someone attempts to start the engine
with an unrecognized key, the engine will
not start, thereby helping to prevent
vehicle theft.
If you have a problem with the
immobilizer system or the key, consult an
Authorized Mazda Dealer.
CAUTION
Radio equipment like this is governed by
laws in the United States.
Changes or modifications not expressly
approved by the party responsible for
compliance could void the user's
authority to operate the equipment.
 To avoid damage to the key, do not:
 Drop the key.
 Get the key wet.
 Expose the key to any kind of magnetic
field.
 Expose the key to high temperatures
on places such as the dashboard or
hood, under direct sunlight.
 If the engine does not start with the
correct key, and the security indicator
light keeps illuminating or flashing, the
system may have a malfunction. Consult
an Authorized Mazda Dealer.

NOTE
The keys carry a unique electronic code.
For this reason, and to assure your
safety, obtaining a replacement key
requires some waiting time. They are
only available through an Authorized
Mazda Dealer.
Always keep a spare key in case one is
lost. If a key is lost, consult an
Authorized Mazda Dealer as soon as
possible.
If you lose a key, an Authorized Mazda
Dealer, will reset the electronic codes of
your remaining keys and immobilizer
system. Bring all the remaining keys to
the Authorized Mazda Dealer to reset.
Starting the vehicle with a key that has
not been reset is not possible.
▼ Operation
NOTE
The engine may not start and security
indicator light may illuminate or flash if
the key is placed in an area where it is
difficult for the system to detect the
signal, such as on the dashboard or in
the glove compartment. Move the key to
a location within the signal range,
switch the ignition off, and then restart
the engine.
Signals from a TV or radio station, or
from a transceiver or mobile telephone
could interfere with your immobilizer
system. If you are using the proper key
and the engine fails to start, check the
security indicator light.
Arming
The system is armed when the ignition is
switched from ON to off.
The security indicator light in the
instrument cluster flashes every 2 seconds
until the system is disarmed.

Disarming
The system is disarmed when the ignition
is switched ON with the correct
programmed key. The security indicator
light illuminates for about 3 seconds and
then turns off. If the engine does not start
with the correct key, and the security
indicator light remains illuminated or
flashing, try the following:
Make sure the key is within the
operational range for signal transmission.
Switch the ignition off, and then restart the
engine. If the engine does not start after 3
or more tries, contact an Authorized
Mazda Dealer.
NOTE
If the security indicator light flashes
continuously while you are driving, do
not shut off the engine. Go to an
Authorized Mazda Dealer, and have it
checked. If the engine is shut off while
the indicator light is flashing, you will
not be able to restart it.
Because the electronic codes are reset
when the immobilizer system is repaired,
the keys are needed. Make sure to bring
all the keys to an Authorized Mazda
Dealer, so that they can be programmed.

NOTE
The engine starts by pressing the push
button start while depressing the brake
pedal. To switch the ignition position,
press the push button start without
depressing the pedal.
Do not leave the ignition switched ON
while the engine is not running. Doing
so could result in the battery going
dead. If the selector lever is in the P
position, and the ignition is in ACC, the
ignition switches off automatically after
about 25 minutes.

switch the ignition off, set the parking
brake, and make sure the selector lever is in
P position:
Leaving the driver's seat without switching
the ignition off, setting the parking brake,
and shifting the selector lever to P position
is dangerous. Unexpected vehicle
movement could occur which could result
in an accident.
In addition, if your intention is to leave the
vehicle for even a short period, it is
important to switch the ignition off, as
leaving it in another position will disable
some of the vehicle's security systems and
run the battery down.
ACC (Accessory)
Some electrical accessories will operate
and the indicator light (amber) illuminates.
NOTE
The keyless entry system does not function
while the push button start has been
pressed to ACC, and the doors will not
lock/unlock even if they have been locked
manually.

This is the normal running position after
the engine is started. The indicator light
(amber) turns off. (The indicator light
(amber) illuminates wh en the ignition is
switched ON and the engine is not
running.)
Some indicator lights/warning lights
should be inspected before the engine is
started (page 4-12).
