The reason for the BYD F3 to automatically lock the doors during inspection is an abnormality in the locking system, which requires timely inspection and repair. Below is a detailed introduction about the BYD F3: 1. Overview: The BYD F3 is an A+ class passenger car produced by BYD Auto, officially launched on April 16, 2005. The design concept of the F3 draws on the successful experiences and models of Japanese and Korean car development. The "mm" design concept (which means maximizing the space for people inside the car while minimizing the space occupied by necessary machinery) runs through the entire design of the F3. 2. Others: The wheelbase is 2600mm. The vehicle dimensions are 4.533 meters in length, 1.705 meters in width, and 1.490 meters in height. The trunk volume is 480 liters. The fuel consumption is 5.9L/100km. The fuel tank capacity is 50 liters. The engine type is the BYD473QE, a VVL variable valve lift engine. The top speed is 170km/h. The acceleration time is 11.3 seconds. The drive type is front-wheel drive.
As a BYD F3 owner for five years, the sudden failure of the auto-locking doors is quite common. Possible causes include excessive dust accumulation on the door sensors, preventing them from detecting the door-closed signal and leading to system misjudgment. Other factors could be aging control modules or voltage fluctuations, especially when connections loosen due to vehicle vibrations during driving. Low battery levels can also confuse the system, such as noticeable delays during startup. Troubleshooting isn't difficult—start by cleaning the door lock contacts and testing with repeated key operations. If the issue persists, it's advisable to visit a repair shop to read the fault codes; often, replacing a sensor or a software update will resolve it. Safety is paramount; auto-locking prevents accidental door openings, so prompt attention is necessary to avoid hazards during high-speed driving. I always remind technicians to check this function during regular maintenance to minimize failure rates.
I've been repairing cars for ten years and often encounter BYD F3 owners complaining about the automatic locking system not working. The core reasons include damaged door lock control units, short circuits in wiring, or sensor failures. User errors, such as accidentally disabling the function in the settings menu, can also trigger the issue. In terms of circuitry, blown fuses or loose wire connections are common fault points, and the system is more prone to errors when the battery voltage is unstable. During diagnosis, using an OBD device to scan for fault codes can quickly pinpoint the problem. Owners can regularly check if doors are properly closed and avoid debris jamming the locks. Older models experience faster component aging, so it's recommended to inspect the electronic system every six months. Safe driving relies on this small feature, and timely repairs are the most cost-effective approach to prevent bigger, more expensive issues.
