Finally got the door open. After purchasing a replacement door lock I could see how it worked. I was able to remove a small amount of plastic and get at the part I needed to move in order to get the lock to release. The first movement released the first catch of the double lock and released the door onto the second lock.. The second release needed a bit of tapping and moving the door to jump the catch. It didn't unlock but it did jump the retainer. Not an easy fix.
