What is the reason for the unresponsive central lock in Wuling Hongguang?

[LaAllison]

Possible reasons include poor contact at the central lock's contact points, which can be resolved by cleaning with sandpaper. Here is more information about the central lock functions: 1. Central Control: When the driver locks the door beside them, all other doors are simultaneously locked. The driver can unlock all doors with the door lock switch or open a single door individually. 2. Speed Control: When the vehicle reaches a certain speed, all doors automatically lock to prevent passengers from accidentally opening the doors by operating the door handles. 3. Individual Control: In addition to the driver's door, separate spring lock switches are installed on other doors, allowing independent control of each door's locking and unlocking.
