WA R N I N G
Do not leave the key in your vehicle with
children and keep them in a place where
your children will not find or play with
them:
Leaving children in a vehicle with the key is
dangerous. This could result in someone
being badly injured or even killed. Children
may find these keys to be an interesting toy
to play with and could cause the power
windows or other controls to operate, or
even make the vehicle move.
CAUTION
Because the key (transmitter) uses
low-intensity radio waves, it may not
function correctly under the following
conditions:
 The key is carried with communication
devices such as cellular phones.
 The key contacts or is covered by a
metal object.
 The key is near electronic devices such
as personal computers.
 Non-Mazda genuine electronic
equipment is installed in the vehicle.
 There is equipment which discharges
radio waves near the vehicle.
 The key (transmitter) may consume
battery power excessively if it receives
high-intensity radio waves. Do not place
the key near electronic devices such as
televisions or personal computers.
To avoid damage to the key (transmitter),
DO NOT:
 Drop the key.
 Get the key wet.
 Disassemble the key.
 Expose the key to high temperatures
on places such as the dashboard or
hood, under direct sunlight.
 Expose the key to any kind of magnetic
field.
 Place heavy objects on the key.
 Put the key in an ultrasonic cleaner.
 Put any magnetized objects close to
the key.

A code number is stamped on the plate
attached to the key set; detach this plate
and store it in a safe place (not in the
vehicle) for use if you need to make a
replacement key (auxiliary key).
Also write down the code number and
keep it in a separate safe and convenient
place, but not in the vehicle.

If your key (auxiliary key) is lost, consult
your Authorized Mazda Dealer and have
your code number ready.

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
