use the key
to reset the FOB you get in the car, shut the doors. Then hold the cetral locking lock all button down until the doors lock and unlock. The imobilser light goes solid red. At this point you have 10 seconds to click the new unprogrammed FOB. the doors will unlock and lock. Job done
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
The flap locks and unlocks with the central locking so it should unlock either with the plip key or the button next to the handbrake. It if fails to unlock then the solenoid is faulty but you can release it by removing the drivers' side light cover in the boot and pulling on the cable.

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.
