What is the method for removing and installing a car door lock?

To remove and install a car door lock, start by prying open the rearview mirror adjustment panel from below. Here are some relevant details about car doors: 1. The difference between OEM doors and original doors: The only distinction between OEM doors and original doors lies in the painting process. Original doors are painted along with the entire vehicle, while OEM doors leave the factory unpainted and are painted separately during later replacement. As long as professional installation is ensured, there will be no significant difference in quality and integrity between OEM and original doors. 2. Reasons not to recommend aftermarket doors: The stamping molds for aftermarket doors differ from those for original and OEM doors, resulting in precision gaps. Additionally, the materials vary, leading to different rigidity levels, and the prices are generally cheaper. Typically, the sheet metal of aftermarket doors is slightly thinner, and some anti-corrosion processes do not meet OEM standards.
I've tried disassembling and installing car door locks several times. It's not too difficult overall, but requires careful preparation of tools and attention to safety. First, prepare a Phillips screwdriver, wire cutters, and a plastic pry bar, and wear gloves to prevent cuts. Step one: ensure the car is parked and turned off, and disconnect the negative battery terminal to avoid short circuits. When removing the door panel, use the pry bar to carefully pop open the clips from the edges—don't pull hard to prevent interior damage. Then locate the door lock assembly, remove the mounting screws, and when disconnecting the wiring harness, remember the color coding to avoid confusion. Installing the new lock follows the reverse steps: reconnect the wires and test the lock function before securing the screws. Finally, reattach the door panel, making sure all clips snap into place. The whole process might take one or two hours—it's best to refer to the vehicle manual or online tutorials to avoid issues like improper door sealing or rattling. After installation, remember to lubricate the lock tongue to extend its lifespan.
