Keyless Entry System

Keyless Entry System

This system uses the key buttons to remotely lock and unlock the doors and the liftgate, and opens/closes the liftgate.

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.

For vehicles with the type A instrument cluster, check the displayed message for more information and, if necessary, have the vehicle inspected at an Authorized Mazda Dealer, according to the indication.

  • KEY Warning Light (Red)

    Refer to Warning/Indicator Lights (Search).

  • Ignition Not Switched Off (STOP) Warning Beep

    Refer to Ignition Not Switched Off (STOP) Warning Beep (Search).

  • Key Removed from Vehicle Warning Beep

    Refer to Key Removed from Vehicle Warning Beep (Search).

If you have a problem with the key, consult an Authorized Mazda Dealer.


If your key is lost or stolen, consult an Authorized Mazda Dealer as soon as possible for a replacement and to make the lost or stolen key inoperative.

  • 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 (Search).

  • 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 (Search), 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.
