immobilizer system or the key, consult an
Authorized Mazda Dealer.

Mazda cannot guarantee the immobilizer
system
’s operation if the system has been
modified or if any add-on equipment has
been installed to it.
NOTE

stays on when the ignition switch is
turned to the ON position, the
engine will not start.

or from a transceiver or a mobile
telephone, could interfere with your
immobilizer system. If you are
using the proper key and your
engine fails to start, check the
warning light. If it is flashing,
remove the ignition key and wait 2
seconds or more, then reinsert it and
try starting the engine again. If it
doesn
’t start after 3 or more tries,
contact an Authorized Mazda

Authorized Mazda Dealer and have
it checked. If you shut off the

• Since the electronic codes are reset
when repairing the immobilizer
system, the keys are needed. Bring
all the existing keys to the
Authorized Mazda Dealer.
NOTE
•The keys carry a unique electronic
code. For this reason, and to assure
your safety, obtaining replacement

They are only available through an
Authorized Mazda Dealer.
• Always keep a spare key, in case
one is lost. If a key is lost, contact
an Authorized Mazda Dealer as
soon as possible.

all the remaining keys to the
Authorized Mazda Dealer to reset.

has not been reset is not possible.
To avoid damage to your vehicle, do
not modify the system or install any
