The method to set the beep sound when locking Nissan Sylphy is to press both the unlock and lock buttons on the remote control simultaneously for more than three seconds to switch between two modes. Taking the Sylphy 2021 Classic 1.6XE Manual Comfort Edition as an example: The manufacturer of this car is Dongfeng Nissan, classified as a compact car with gasoline energy type. The car dimensions are 4631mm in length, 1760mm in width, and 1503mm in height, with a wheelbase of 2700mm. It's a 4-door 5-seater sedan with a 5-speed manual transmission, maximum speed of 188 km/h, and naturally aspirated intake form.

I recently adjusted the lock beep sound for my Sylphy. With the car key near the vehicle, press the start button twice without stepping on the brake to power up the entire car. When the dashboard lights up, quickly navigate to the settings menu on the central console. Look for the 'Vehicle Settings' and then the 'Safety & Alerts' option, where you'll find a 'Lock Beep Sound' switch. Turn it on, and you'll hear two beeps when locking the car. Some newer Sylphy models allow you to set one or two beeps, but my 2017 model only has an on/off option. Just a reminder: the side mirrors automatically folding in is the real confirmation that the car is locked—relying solely on the sound can sometimes be misleading.

The operation is actually quite straightforward. I just helped a colleague set it up last weekend. First, sit in the car and close the door. With the key in the sensing area, quickly press the ignition button twice (make sure not to press the brake pedal). Wait for the dashboard to power on, then immediately fiddle with the directional buttons on the left side of the steering wheel. Once the settings menu appears, select 'Vehicle Information,' find the security settings with the small speaker icon, and enable the 'Lock Confirmation Sound' function. Remember to test it outside the car: after pressing the lock button on the key, it should beep twice and the hazard lights should flash twice to confirm it's working correctly. Don't bother trying this on older models without this feature—my neighbor couldn't get it to work even after updating the system on his 2012 Sylphy.

This feature is super practical! Here's how I set it up: After entering the car, press the start button twice to power on (don't start the engine). Open the 7-inch center control screen, swipe left with your finger to enter the menu, and find 'Vehicle Settings' like flipping through a phone. Tap 'Door Lock Settings' under the safety items, then toggle on 'Lock Confirmation Beep' to complete the setup. During testing, note that two beeps when locking in a parking lot are normal, but if it also beeps when unlocking, it might trigger the anti-theft alarm—check if all four doors and the trunk are properly closed. Last time, my car kept alarming because the trunk wasn't fully shut. Now, I always check the folding mirrors to confirm it's locked.
