2019 MAZDA MODEL MX-5 MIATA RF battery replacement

Keys
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 driver must carry the key to ensure the
system functions properly.

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.
NOTE
The keyless entry system operation may
vary due to local conditions.
The keyless entry system is fully
operational (door/fuel-filler lid lock/
unlock) when the ignition is switched
off. The system does not operate if the
ignition is switched to any position other
than off.
If the key does not operate when
pressing a button or the operational
range becomes too small, the battery
may be weak. To install a new battery,
refer to Key Battery Replacement (page
6-33).
Battery life is about one year. Replace
the battery with a new one if the KEY
indicator light (green) flashes in the
instrument cluster (for vehicles with a
type A instrument cluster (page 4-26),
messages are displayed in the
instrument cluster). Replacing the
battery about once a year is
recommended because the KEY warning
light/indicator light may not illuminate
or flash depending on the rate of battery
depletion.
Additional keys can be obtained at an
Authorized Mazda Dealer. Up to 6 keys
can be used with the keyless functions
per vehicle. Bring all keys to an
Authorized Mazda Dealer when
additional keys are required.
