Keskuslukitus

Keskuslukitus, often translated as central locking, is a system found in vehicles that allows the driver to lock and unlock all doors simultaneously from a single point. This is typically achieved through a switch on the driver's door or a remote key fob. The system operates using electric actuators or pneumatic pumps that send signals to lock and unlock mechanisms on each door.

The primary function of keskuslukitus is convenience and security. It eliminates the need to manually lock each door individually, saving time and effort. Furthermore, it ensures all doors are locked consistently, enhancing the vehicle's security. Many modern systems also incorporate features like automatic locking when the vehicle is in motion or remote unlocking for passengers.

The technology behind keskuslukitus has evolved significantly. Early systems were often pneumatic, relying on compressed air to operate the locking mechanisms. Modern systems are predominantly electric, offering faster operation and greater reliability. The integration of remote keyless entry, where the driver can lock and unlock the car from a distance, has become a standard feature in most new vehicles. Some advanced systems even include features like keyless entry and start, where the car recognizes the presence of the key fob and allows the driver to enter and start the engine without physically using the key.
