This system uses the key buttons to
remotely lock and unlock the doors,

The system can start the engine
without having to take the key out of
your purse or pocket.
It can also help you signal for attention
or help.
Operating the theft-deterrent system is
also possible on theft-deterrent
system-equipped vehicles.

System malfunctions or warnings are
indicated by the following warning
lights or beeps.
Check the displayed message for more

NOTE
The keyless entry system operation
may vary due to local conditions.
The keyless entry system is fully
operational when the ignition is
switched off. The system does not
operate if the ignition is switched to
any position other than off.

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 6-29).
Battery life is about 1 year. Replace
the battery with a new one if the
messages are displayed in the
instrument cluster. Replacing the
battery about once a year is
recommended because the KEY

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.
