The central locking is controlled by an electronic device called the central locking control unit that is bascially a relay. There are normally 4 wires that go to each door. Two of the wires connect to the lock mechanism and tell the central locking control unit whether the doors are locked or not. The other two wires connect to the actuator which can either take the form of a motor or an electro magnet. The Central locking control unit connects these wires in one direction to lock and the opposite direction to unlock the doors.
Most modern cars also have a remote sensor that detects the signal from a remote key fob. This send a radio or IR signal to a detector which then connects to the central locking control unit to tell the car to lock or unlock. This uses a coded signal that is unique to that particular key fob.

The central locking means if you lock the door of the driver side by the key from outside or from inside then all the four doors and the boot door gets locked. And inversely if you open then all doors open. Key less entry is a bit advanced version of this wherein you don't have to turn the key to lock or unlock. In this a small console is fitted inside the car and you get a remote key chain with buttons for locking and uncloking. You press the button for locking and the all the doors lock and similarly unlock as well.
