A central locking system is a feature in vehicles that allows the driver to lock or unlock all doors simultaneously from a single point, usually the driver's door or a remote key fob. This system enhances convenience and security, as it prevents the need to manually lock each door individually. Most central locking systems use an electronic mechanism that activates the locks through a motor or solenoid. Some advanced systems may also include features like keyless entry, where the vehicle can be unlocked automatically when the key fob is in close proximity, improving ease of access for the driver and passengers.
