How to disable the automatic locking function of BYD F3?

Introduction to disabling the automatic locking function of BYD F3: Insert the key and turn it to the ACC position, then open and close the car door twice. Next, turn the key to the ON position - at this point the warning light will stay on. Press the lock button on the remote control once, and the alarm will sound twice to confirm the operation. Below is an introduction to the automatic locking function: 1. The purpose of the automatic locking function is anti-theft. It quickly locks the doors after driving starts, preventing door-pull robberies during traffic jams or at red lights, providing certain security benefits. It also protects child passengers by preventing them from opening door handles while the vehicle is in motion. 2. Automatic driving lock is a safety measure. The vehicle's computer automatically locks all doors when it detects the car is about to move. There are multiple detection methods, with most systems using speed as the determining factor - doors automatically lock when reaching preset speeds (usually 10-20 km/h). Some vehicles automatically lock doors when the driver shifts into D gear.

I've been driving a BYD F3 for several years, and disabling the auto-lock feature is quite simple. Find some time to sit in the driver's seat, close all the doors, and press the start button twice without stepping on the brake to turn on the dashboard and enter ACC mode. Then, hold down the lock button on the driver's side door for about 10 seconds until you hear a beep or see the warning lights flash a few times, which means the function has been disabled. Normally, when I drive in the city, the automatic locking as soon as the car starts moving feels a bit unnecessary, especially when waiting at traffic lights. If I want to open the door for some fresh air, I have to unlock it first, so disabling it makes things much more convenient. However, safety shouldn't be overlooked—always remember to manually lock the doors after parking, just in case. If the car's system updates or the battery is replaced, you might need to repeat the process. Overall, the procedure is pretty straightforward, and you'll get the hang of it after trying once, so don't worry about damaging anything.

Having worked in the automotive repair industry for many years, dealing with the BYD F3 automatic door lock deactivation is quite common. The operating steps are: Sit in the driver's seat and close the door tightly, then press the ignition switch twice consecutively without stepping on the brake to enter ACC mode. Next, hold down the door lock button for 5-10 seconds, waiting for the warning light to flash or a beep sound to confirm. This feature is generally designed for anti-theft purposes, and some car owners disable it due to frequent parking entries and exits or concerns about accidental locking. From a safety perspective, I recommend keeping the automatic door lock function to reduce risks, especially in high-traffic areas. If there is no response during the steps, check whether the fuse is intact or if the battery has sufficient power. After the operation, test it several times to ensure normal functioning. During regular maintenance, pay attention to the stability of the electronic systems.
