Mazda 3 Owners Manual: Keyless Entry System
This system uses the key buttons to remotely lock and unlock the doors and the liftgate/trunk lid, and opens the trunk lid.
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.
Operating the theft-deterrent system is also possible on theft-deterrent systemequipped vehicles.
Press the buttons slowly and carefully.
System malfunctions or warnings are indicated by the following warning lights or beeps.
- KEY Warning Light (Red) Refer to Warning/Indicator Lights on .
- Ignition Not Switched Off (STOP) Warning Beep Refer to Ignition Not Switched Off (STOP) Warning Beep on .
- Key Removed from Vehicle Warning Beep Refer to Key Removed from Vehicle Warning Beep on .
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.
| 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 .
- Battery life is about one year. Replace the battery with a new one if the KEY indicator light (green) flashes 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.
