If you reach Valley Wind works in Pokémon Brilliant Diamond and Shining Pearl, you must find the factory key to get access to the system. A grunt of Team Galactic has trapped with a few other grunts in the building to prevent someone from coming in. The Works Key is not in the immediate vicinity, so you have to make a short detour to a nearby city. Here you will find the factory key in Pokémon Brilliant Diamond and Shining Pearl.
Works Key Position in Pokémon Brilliant Diamond and Shining Pearl
The Works Key is not far west of Valley Wind works. Go back to Flo aroma Town and go to the flowerbed in the northwestern corner of the area. Go through the hidden between the trees to reach Flo aroma Meadow.
As soon as you enter Flo aroma Meadow, you will meet two team Galactic grunts that block the way forward. Defeat them in a fight to continue. After defeating the two granters, the man they bothered gives them the factory wrench and something honey as a reward. With the key in hand, you can return to the Valley Wind works.
As soon as you return to Valley Wind works, you can use the key to get in. You have to fight against the grunt of Team Galactic, which has locked together with some other team Galactic members. Mars, one of the commands of Team Galactic, is also present in Valley Wind works, and they have to fight against them before they can continue to Eternal City.
With the Clearing Valley Wind works from Team Galactic members, you can also catch a Brighton. Brighton encounters are limited to one per week and can only be found at Valley Wind works, which makes it quite difficult to get to them. It is a great ghost / flying guy you can add to your team, and its one of the coolest Pokemon of Singh.
