That's good to hear. Maybe a cycle of locking and unlocking the car reset the controls?
WRT the door card, Neal Hankinson, who has helped a lot with my car and knows the 916 inside out, does them very slickly. He unscrews the door lock button at the top, almost completely, so that it stands as proud as it can without coming off. It can then act as a guide to the correct card position.
He then lines up the card visually so that the "mushrooms" are lined up to where they should fit, before pressing gently but firmly with his leg in the middle and hands either side to spread the pressure across the whole card whilst moving the card vertically to slip over the mushrooms. It then pops on seemingly pretty easily!
