What is the solution for the BYD F3 central locking system malfunction?
2 Answers
The solution for the BYD F3 central locking system malfunction is: 1. Check if the fuse is blown; 2. Contact a professional auto repair shop and seek assistance from a specialist; 3. Check whether you can manually open and close all four doors. If you can, the issue is with the remote key; if you cannot, the problem lies with the anti-theft control module or wiring. Taking the 2020 BYD F3 as an example, its body dimensions are: length 4533mm, width 1705mm, height 1490mm, with a wheelbase of 2600mm, a fuel tank capacity of 50 liters, and a trunk capacity of 430 liters. The 2020 BYD F3 features a front MacPherson strut independent suspension and a rear torsion beam non-independent suspension. It is equipped with a 1.5L 109 horsepower L4 engine, delivering a maximum horsepower of 109PS, a maximum power of 80kW, and a maximum torque of 148Nm, paired with a 5-speed manual transmission.
My F3 also experienced central locking failure issues before. Start troubleshooting from the simplest solutions. First check if the remote control battery is low on power - this is often the main cause, especially if the key hasn't had its battery replaced for several years. Try installing a new battery. If that doesn't work, locate the fuse box (usually under the hood or dashboard), refer to the manual to find the locking-related fuse (typically marked 15A), and check if it's blown. Replacing a fuse costs less than 1 yuan and is easy to do.
If both battery and fuse are fine, consider possible stuck or faulty door lock actuators - this would require removing door panels to inspect internal mechanisms or check for loose/oxidized wiring connections. If DIY-ing, use proper tools for wire adjustments but avoid forcing anything to prevent damage.
If these steps fail, promptly visit a professional repair shop for ECU or motor diagnosis using specialized equipment - they're more experienced with such issues. For prevention, regularly check remote batteries and keep keys clean to avoid recurrence. Remember: systematic troubleshooting prevents unnecessary expensive part replacements.
