A central locking system is a feature in vehicles that allows the driver to lock or unlock all doors simultaneously using a single control, typically a button on the key fob or inside the car. This system enhances convenience and security, as it ensures that all doors are secured at once, reducing the risk of leaving a door unlocked. Most central locking systems use electronic actuators to control the locking mechanism in each door. When the driver activates the system, a signal is sent to these actuators, which then engage or disengage the locks. This technology is commonly found in modern cars and is often integrated with other security features like alarm systems and keyless entry.
