Keys
CAUTION
Radio equipment like this is governed
by laws in the United States.
Changes or modifi cations 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/liftgate/trunk 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 dead. To install a new battery,
refer to Key Battery Replacement (page
6-40 ).
Battery life is about one year. Replace
the battery with a new one if the KEY
indicator light (green) ashes in the
instrument cluster. Replacing the battery
about once a year is recommended
because the KEY warning light/
indicator light may not illuminate or
ash 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.
