How to Replace the Door Lock Assembly of a Sail?

The owner should first prepare a cross-head screwdriver and a hex key for removing the door lock. Roll the window up to the top; otherwise, it will be difficult to work inside the door. Then, use bent-nose tweezers to remove the spring clip inside the window crank's pivot part. Remove the triangular plastic trim cover below the window by prying it towards the window with a small flat-head screwdriver. Avoid applying force perpendicular to the window. Carefully pry it open, avoiding excessive force to prevent the need for glue, which could cause more trouble. Remove the screws around the interior door panel and the two in the middle, as well as the layer of adhesive paper inside the door.
I've worked on many car repairs before, and the process of replacing the Sail door lock mechanism is quite particular. Prepare a Phillips screwdriver, a new lock mechanism, and a pry bar, ensuring the car is turned off and the battery is disconnected for safety. Start with the door trim panel, removing all screws, then carefully pry off the panel with the pry bar, being careful not to damage the clips or wiring. After peeling off the waterproof membrane, you'll see the position of the lock mechanism—loosen the mounting screws, unplug the wiring connector, and remove the old lock mechanism as a whole. When installing the new lock mechanism, align the holes, tighten the screws, reconnect the wiring, and reattach the waterproof membrane. When reassembling the trim panel, make sure all clips are securely fastened, otherwise, there might be rattling noises while driving. After completion, test the lock function to ensure smooth operation. The whole process is best done with two people to avoid tangling the wiring harness, which could affect the safety of the door's opening and closing. I recommend inexperienced individuals consult the repair manual or seek a professional mechanic to avoid messing it up.
As someone who enjoys tinkering with cars, I've tried replacing the door lock on my Sail myself, and I'd say it's a beginner-level DIY project. First, gather your tools: a flathead screwdriver, a new lock assembly, and some lubricant. Remove the door panel screws, gently pry it open along the edges—don't be too rough to avoid damaging the interior. After peeling back the waterproof membrane, loosen the screws on the lock assembly and unplug the connector (take a photo to note the wiring in case of mistakes). Install the new lock assembly, ensuring it's positioned correctly, and tighten the screws. When reassembling, apply some lubricant to the clips to reduce friction. Test the lock a few times—it should operate smoothly when opening and closing. The whole process takes about an hour. It saves you money on shop fees, but you need to be careful—I accidentally snapped a wire my first time and had to redo it. Learning some car repair skills is pretty handy, especially for car owners with time to spare who want to save a hundred bucks or so.
