I opened the door manually with the key, closed it, hold the key in closed position for about 10 seconds, opened it. Hold the key in opened position for about 10 seconds. The system resetted itself. The remote works again and my trunk works again aswell.

Dear Marnix, I'm facing a problem the same as yours.
My English is not good, so I'm not sure if I understand what you mean correctly.
"Hold the key in opened position" means to hold the "unlock" button on the keyfob for 10 sec? or does it mean the opening/closing status of the door, so I just grab the key and stand there count seconds?
Much appreciated if anyone can guide me!
