loosen all the screws arround that you can see, aswell on the doorhandle where you open the door from inside.
Now the tricky part!!! the cover arround the doorhandle needs to go off, if you don't be carefull, they break on 1 side, they cost 65€ ( in belgium) for 1!!! so they are very expensive. I toke them off with 4 tiny screwdrivers to loosen the clips.
If all that is done, then the doorcard is completeley loose.
