Dont think many will have had the Door Cards off, and if they have the are "with all respect" DIY Men and do not attempt it every day.
You can do some severe damage to the Card if you apply force in the wrong area.
I can see the panel as some Press clips in, you need to either purchase or make a SPOON/FORK this is to remove these Clips, then gentle ease the panel away from the frame of the Door until you can see some sort of holding, with a little force the Door Card should pop off however it is inevetable you will break some of the retianing Clips, thats why we nicked named them "ONCES" because they only work Once.
