You use your Team Rocket Disguise to get in. Then, your rival comes in and blows your cover. Go up to 5f and find out what up's with the director. After you get the basement key, head to GoldenRod Tunnel. Open the door on 3f and go inside. Then showdown with team rocket executive.
Hope this Helps!

In Lavender Town, you can't. In Goldenrod City, after your 7th badge.
You'll need to disguise yourself as a rocket member first.
You cant, it gets nuked.
you can go to blackthorn city
go t the radio tower and save the manager
Beat the grunts, get the key from the Radio Tower Chairman at the hideout, beat Archer and Ariana
After you save the radio tower in goldenrod city a man comes in and gives you the rainbow wing as a reward.
In Goldenrod City
You must defeat the Team Rocket Grunts and Executives at the Radio Tower, and Petrel will give you a key to the locked door in the Goldenrod Tunnel, then navigate through the Tunnel, defeating Grunts along the way, until you finally find the Director at the bottom of the tunnel. He will thank you for finding him and ask you to save the Radio Tower. When you do, he will give you the Rainbow Wing in HeartGold, or the Silver Feather in SoulSilver. I hoped this helped you!
