A combination wrench works too. The closed end has the double hex on it, I believe. When I tore mine apart, the "Out" was the hardest to remove due to the years of syrup buildup. The gas in was relatively easy.
Here's a pic. I have a 72 piece socket set. I bought it JUST for these kegs, too. My deepest sockets spin free. Oh, and my kegs have two of these star things on top of each other on the "In" side/cO2 side.
