Ok, this is how I took out the door card (I know most of you guys know how to do this, but hopefully it'll be helpful for someone)
Remove door handle cover and door hold and carefully pop out clips surrounding door card.
I found that pushing the area around the window crank didn't give me enough room to push off the circlip, so I removed the sponge behind the crank.
Should be able to just cut up a new sponge
Which gave me plenty of room
Oh, and it took me AGES to find the damn circlip after I popped it off
