Hi everyone. My door's lock started playing up a few days ago. Firstly it was when I opened my door when engine was running or when the key was turned on first scale (ignition on before turning the engine on). Then I heard a sound of double tak just like the sound when we unlock the car by pressing the internal lock - unlock switch in front of the gear stick.   Since yesterday, this sound appears only when I am turning the key to position one (dash lights on and checking but engine still off).
