Seems I have the same problem (I brought it on myself) I noticed the bolt inside the door which holds the door handle on wasnt there. So in my wisdom replaced it. Turns out the bolt was too long and now my door wont work. To make it worse didnt notice this until I had shut the door!!!!!!!!!!!!
Can PM me how you take the door card off with the door closed? Or are you able to get to all the screws anyway?
