How many keys does the Mazda3 come with?
1 Answers
Mazda3 comes with four keys: two electronic and two mechanical. Remote Key Introduction: A remote key utilizes the wireless remote function of the central locking system, allowing you to unlock and lock the doors from a distance without inserting the key into the lock. Remote Key Working Principle: In simple terms, the key first emits a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator (motor or electromagnetic coil) performs the locking or unlocking action.
