Ahh thanks, I shall give that a go in trying to open it! I phoned Kwik Fit this morning, (purely cos I need to get MOT done asap) and they said that the rear door not opening would fail the MOT. So I called a local MOT centre that could potentially do the repair as well and the stated that the rear door not opening is classed as an advisory. He even went away to check it. Booked in tomorrow so hopefully should go through OK!
