NOTE
The keyless entry system operation may
      
vary due to local conditions.
The keyless entry system is fully
      
operational (door/liftgate 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
6-36 ).
Battery life is about one year. Replace
      
the battery with a new one if the KEY
indicator light (green) fl ashes in the
instrument cluster (for vehicles with
a type A instrument cluster (page
4-32 ), 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 fl 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.
