The special key required is just the regular key, with the tip filed off. Turn 90 cw, and pull the plug out. The top pins extend into the plug cavity, but don't come out. The bullet shaped plug cap pushes the top pins back into the shell when put the plug back. To make it all work, the top pins are VERY rounded. Very easy to pick. And I have found some duplicate keys will pull the plug without any tip filing! If you have one of these, make sure you test all keys to see if they pull the plug, or you will be on your hands and knees with a flashlight and tweezers eventually.
