Excellent you've smashed it people.. 💪With a plastic pry tool, pry the bottom left corner outwards. Screws aren't the only thing holding the door card. You have a slew of clips that also hold the card to the door. They are awful clips and you are most likely to snap at least a few of them. You can buy repayments from ebay.
Like spacecadet mentioned. When you remove the top half of the door card. Be sure to keep the card held close to you. Because you'll need to remove the door handle cable and the connectors for your switches and speaker. Before you can fully remove the door card.
