First you have to tell DgKey to locate the map. You can do this simply by opening the map in-game, and then clicking the map button . A message will show that the map was found and from now on DgKey will automatically update the map whenever you open it.
You can do the same thing for the player list by clicking the the button with the dg ring while the party interface is visible. Loading the player list will automatically load the stats of your team and allows you to use the connect feature.
You can connect by simply clicking the connect button after you've set the party. The button will become green when you are connected. Connecting will keep your map and keys synced with other dgkey users in your team. You can also notify Your team of a location on the map by holding alt and clicking on the map.
Select a tile on the map and type one of the following key combinations to add a key. Keys should be placed on the ? room behind the door, this way it is clear what door the the key belongs to.
