Go to valor lakefront and go inside the "forest" near the house with the girl who is looking for her key. Then beat the Galactic dudes and the commandor. :)

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)
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.
