How to Repair a Faulty Car Central Locking System?

[KingLynn]

Single locking is purely mechanical; the car can be opened from inside under any circumstances. Once locked, it can be opened from inside but not from outside. Currently, most car central locking systems can be set to auto-unlock. If the vehicle itself cannot be configured, you can also visit a 4S dealership to have it set up using a computer.

I've also encountered the central locking system in the car breaking down several times. That time, I solved it myself by checking the manual. First, check the fuse, usually located in the fuse box near the driver's seat, and look for the one labeled door lock. If it's blown, try replacing it with a new one, and it might just fix the problem. If all the doors are malfunctioning, there's a high probability it's a fuse issue. Sometimes, if a single door doesn't respond, the door lock actuator might be broken, and you'll need to remove the inner door panel to check. But if you're not familiar with disassembly, don't force it to avoid damaging the wiring. Now, I regularly clean the lock mechanism to prevent failures caused by corrosion. When repairing, it's best to find a knowledgeable friend to help, to avoid wasting money.
