Dave,
Mine also came in damaged, but not to that extent. I lost all the buttons off of the front but they were easily reinistalled. There are two that were already missing. I have cracks at the corners of the front cover. I have considered a good plastic epoxy like JB Weld plastic bonder. It may not work well in the cracks but I have used it to repair a broken knob. I built up the area around the cracks and a small amount of superglue to hold the broken pieces together. My concern with the front cover was that the superglue could form a haze over the bezel so some painters tape probably would need to be added.
There isn't a lot of room in the corners due to the way it fits over the top/bottom covers.
I have a key for mine. It isn't original but a mistake that didn't fit my 4700. It turns just fine in the 4808 so no money was lost. If you need a key made, let me know. It is different than the one used in my 1281.
