the glantic ware house is in velistone city.but i think you need a key.
Go to Veilstone City and go into the Galactic Warehouse
Fly to Veilstone City and go into the Galactic Warehouse and get to the Pokemon of the lakes and rescue them.
after you deafeat Candice go to lake acuity. then go to the big galactic buliding. ( located in the northeast of vielstone city.) then talk to the galactic grunt in front of the building. pick up the storage key that he drops. then go into the warehouse
go in the warehouse and go to top floor, and go in room 2 the right room
You shouldn't have to wait, you need to go the podeum where Cyrus will be tlking then I think looker will soon be there, he is disguised
u catch girantina and then after that you go to veilstone city and go talk to the team galactic person in front of the galactic warehouse I think galactic warehouse it is one on the team galactic places in veilstone city and then he will go somewhere and drop a key which it will be the storage key. Hope this helped and sorry I cant think of the name of the team galactic place it is the biggest building of the team galactic places (in veilstone city)
you have to beat the galactic warehouse, and when/if you beat it you then go into the galactic HQ by entering from the galactic warehouse, and then Looker will come open the door.
When you go to the galactic building in veilstone' go through the it and you will eventuly find it
go on Pokemon Platinum Walkthrough you'll might get the idea.
In platinum, yes.
There is no code. You have to go to Veilstone City and beat Team Galactic and the Gym leader. After that go to an opening in the left where you battled Team Galactic (Team Galatic Warehouse) and you will find the HM Fly.
When you have got the galactic key from the warehouse then you need to go to the other side where you got the warehouse key.use the galactic team to open the door and then you need to find out where the boss is located.then u free the 3 legendary pokemons!
