The central locking system will only work correctly when all doors and the tailgate are properly closed. The vehicle cannot be locked with the key if the driver door is open.
In vehicles with the Keyless Access locking and starting system, the vehicle can only be locked when the ignition has been switched off and the driver door is closed.
If the vehicle is unlocked and not used for a long time (e.g. in your own garage) the vehicle battery could discharge or the engine may not start.
