The steps to replace the door lock actuator of a BYD F3 are: 1. Remove the interior trim panel inside the car to expose the lock mechanism; 2. The actuator is mounted on the lock mechanism. Use tools to remove the old actuator and install the new one. Taking the 2020 BYD F3 as an example, it is a compact car with body dimensions of 4533mm in length, 1705mm in width, and 1490mm in height, with a wheelbase of 2600mm and a fuel tank capacity of 50 liters. The 2020 BYD F3 features a MacPherson strut front suspension and a torsion beam rear suspension. It is equipped with a 1.5L naturally aspirated engine, delivering a maximum horsepower of 109 PS, a maximum power output of 80 kW, and a maximum torque of 148 Nm, paired with a 5-speed manual transmission.
I just replaced the door lock actuator on my BYD F3 by myself, and it was quite a hassle. You need to prepare tools like screwdrivers and plastic pry bars first. Then, slowly remove the door panel liner, being careful not to damage the clips. After taking off the liner, I found the lock actuator module secured with screws. When removing the old part, take photos to remember the wiring positions. After installing the new actuator, carefully connect the wires to ensure they're secure, and test the locking function before reassembling the door panel. The whole process is time-consuming but saves money. I recommend checking the vehicle manual beforehand to buy the right parts and disconnecting the battery before starting to prevent short circuits. Overall, DIY requires patience, and beginners might want to ask a friend for help to avoid damaging the door.
As a tech enthusiast, I believe the key to replacing the BYD F3 door lock actuator lies in a few critical details. First, tool preparation—a Phillips screwdriver and door panel removal tools are essential. When removing the door panel, start by unscrewing the bolts, then gently disconnect the wiring harness connectors. After removing the old actuator, clean the connectors, and ensure the new part matches the model during installation—don’t reverse the wiring. Testing is a must—manually pull the lock tongue to check responsiveness. I recommend taking time to lubricate the new actuator to extend its lifespan. The whole process takes about half an hour, but pay extra attention to avoid damaging the door’s dust seal film, which affects sealing. If stuck, don’t force it—refer to video tutorials or repair manuals for guidance.
