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
Authorised Mazda Repairer.
Always keep a spare key in case one
   
is lost. If a key is lost, consult an
Authorised Mazda Repairer as soon
as possible.
If you lose a key, an Authorised
   
Mazda Repairer will reset the
electronic codes of your remaining
keys and immobilizer system.
Bring all the remaining keys to an
Authorised Mazda Repairer 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
fl ash if the key is placed in an area
where it is diffi cult for the system
to detect the signal, such as on the
instrument panel 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 fl ashes 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
fl ashing, 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 Authorised
Mazda Repairer.
NOTE
If the security indicator light fl ashes
   
continuously while you are driving,
do not shut off the engine. Go to an
Authorised Mazda Repairer and have
it checked. If the engine is shut off
while the indicator light is fl ashing,
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
Authorised Mazda Repairer so that
they can be programmed.
