The reasons why the central locking of the MG MG3 cannot lock: If all the doors cannot be opened, it can be determined that there is a problem with the central locking. If only a single door cannot be opened, it is usually a fault with the door lock actuator, and it can be replaced individually. Before replacement, check if the linkage has come off, as reinstalling it might restore normal function. Introduction to central locking: The full name of central locking is central control door lock, which is an automotive accessory. Using this lock allows for remote opening and locking of doors without inserting the key into the lock hole. It consists of a door lock switch, an actuator, and a controller. Main functions of central locking: When the driver locks the door beside them, all other doors are simultaneously locked. The driver can open all doors at once via the door lock switch or open a single door individually. When the vehicle reaches a certain speed, all doors automatically lock to prevent passengers from accidentally opening the door by operating the door handle. In addition to the door beside the driver, other doors are equipped with separate spring lock switches, allowing independent control of a single door.
I own an MG3 and have also encountered issues with the central locking system not working. There are quite a few common causes, such as a dead battery in the remote key—simply replacing the small battery might do the trick. If a door isn’t properly closed, it could also trigger the fault, so check each door to see if anything is stuck. Another frequent issue is a blown circuit fuse—open the fuse box and check if the corresponding numbered fuse has melted. Additionally, poor contact in the lock actuator or switch can occur, as these components tend to wear out over time. I’d suggest first trying to lock the doors manually with the key. If that doesn’t work, it might be a circuit or module malfunction. It’s best to visit a professional repair shop as soon as possible for a diagnosis—safety first, don’t take it lightly. If such minor issues aren’t addressed promptly, the risk is high, especially if a door unexpectedly opens while driving at night.
