What is Central Locking
Power door locks (also known as electric door locks or central locking) allow the driver or front passenger to simultaneously lock or unlock all the doors of an automobile or truck, by pressing a button or flipping a switch.
Early systems locked and unlocked only the car doors. Many cars today also feature systems which can unlock such things as the luggage compartment or fuel filler cap door. It is also common on modern cars for the locks to activate automatically when the car is put into gear or reaches a certain speed.
Central locking these days gets even better and simpler with remote or key-less entry. This form of central locking doesn’t even require you to physically put the key in the lock. Press the button and the doors will unlock, usually with a “plip” sound. Some sophisticated remote center locking systems can also be incorporated with a garage door opener, making getting in and out even smoother and hassle-free. Some center-lock systems also lock and unlock the fuel cap.
