Why does the old Mazda6 not have a horn sound when locking the car?
2 Answers
Because the battery consumes too much power. Here is some related information about Mazda: Introduction: Mazda, officially Mazda Motor Corporation, is a Japanese multinational automaker listed on the Tokyo Stock Exchange (TYO), ranked 400th in the Fortune Global 500 in 2020. Main models: As of 2021, Mazda's global passenger car lineup includes: SUV series CX-3, CX-30, CX-4, CX-5, CX-8, CX-9, MX-30; Sedan series Mazda2, Mazda3, Mazda6 (known as "Atenza" by FAW Car); Sports car MX-5.
This issue seems quite common. I also experienced the no-sound issue when locking my old Mazda6, which is mostly a setting problem. There's a hidden option in the car to turn off the alert sound. Try holding both the unlock and lock buttons on the key fob simultaneously for a few seconds to see if it activates or resets. If that doesn't work, it might be due to poor horn contact or a blown fuse—check the fuse box in the engine compartment for one labeled "horn." Older cars often have aging electronics, and loose wiring or short circuits can easily cause no sound. Use a multimeter to test the voltage safely; don't force anything to avoid electric shock. Also, pay attention to the remote battery level—low power can affect the signal. If you can't fix it yourself, visit a specialized repair shop for diagnosis. Safety first.
