The reason why the central control of JAC Heyue can lock but cannot open: If all the doors cannot be opened, then it can be determined that there is a problem with the central control. If only a single door cannot be opened, it is usually a failure of the lock actuator, and it can be replaced individually. Before replacement, check if the pull wire has come off, as it might return to normal after installation. Introduction to central control lock: The full name of the central control lock is central control door lock, which is a car accessory. Using this lock, you can remotely open and lock the door without inserting the key into the keyhole. It consists of a door lock switch, actuator, and controller. Main functions of the central control lock: When the driver locks the door next to them, the other doors are also locked simultaneously. The driver can open all doors at the same time through the door lock switch, or open a single door individually. When the driving speed reaches a certain level, all doors can lock automatically to prevent passengers from accidentally operating the door handle and causing the door to open. In addition to the door next to the driver, other doors are equipped with separate spring lock switches, which can independently control a single door.
I just bought a JAC Heyue and ran into the issue where the central locking system can lock but not unlock, which is quite frustrating. I suspect it might be due to a dead battery in the remote key fob or a faulty signal receiver that fails to send the unlock command. Among owners of this JAC model, it’s common to hear complaints about minor glitches in the control module—perhaps a software glitch in the computer board or a loose wiring harness connector. Once, after manually unlocking the door with the key, I found the actuator motor inside the door was stuck, and it only worked again after applying some lubricant. Safety is crucial; being trapped outside the car can be dangerous, so I recommend immediately visiting a 4S shop to check the circuits and fuses. For daily use, avoid exposing the remote to moisture or water, and during regular maintenance, ask the technician to test the locking system to prevent such issues.
