Right, SportSE. I tried several combinations on pressing the key buttons, today. Now, I can open the doors, close the doors with or without using the key. I am able to open the all the windows by pressing and holding the key knob, too. But I couldn‘ close the windows from outside e.g. by holding the close button on the key. I had to enter the car to close the windows by pulling the switches in the door panel.
Is there any function to close the windows with the key from outside?
By the way: I was able to engage the car alarm by using the mechanical key while the windows were open. What a surprise on the supermarket parking slot with lots of other car owners around me. I shouted: Don‘t shoot, it‘s mine. I am rich ;-)
