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.
You lock the car with the central locking. Then unlock it via the key (manually). then turn the key to the first setting, you must do it quickly as it has a timer for the alarm. then you can disconnect the battery and replace/charge it. when you're done, put the battery back in and turn the ignition back off and its back to normal again. It will ask you for a code if you have satnav but its written in the book.
My 2002 Tribute has the same problem, caused by central locking motor failure in the back hatch.
