use the key
from inside. drop rear seats get in boot unlock by hand its a kind of latch. you wont be able to lock it again though unless you get in boot everytime
If the battery goes dead flat the door will still unlock manually with the key.
If you have central locking press the open button twice
Press the unlock button twice it's been set to unlock drivers first on +2004MY settings are on the central display menu
By using central locking system of cars, passenger can lock or unlock all the doors of car pressing a button or flipping a switch.

I have had this problem. The central locking system checks that all of the doors are closed when it is activated. So it has a loop of wires that goes through all the doors (when the doors are closed the loop is complete and the central locking stays locked) What is happening is, some of the wires in the loop have snapped, his happens in the doors, (if you look in the door when it is open, on the hinge side, you will see a black rubber tube that contains the wiring). All of the door wiring will need to be checked and broken wires repaired - this should solve the problem.
It doesnt have a switch. You just open it with your hand. It does have a lock which locks it with the central locking so it should unlock when you unlock the car.
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.
