After u go to the lake of rage and meet lance u go fight team rocket in a house in mahogany town then you go to the radio tower in goldenrod and make ur way up then fight the imPoster director he gives u the key
it depends on what part you're at. just continue to the next cities and eventually you'll be given a key to get into the employee's place in the underground. you'll eventually face off and defeat team rocket.
No, not team rocket. But there is an event in the Ilex Forest where you can battle Giovanni.
You need to go to the radio tower in Goldenrod and face team rocket again.
this is only part of it but you have to get the uniform form the team rocket grunt were you take your pitcher but he finks that your a new recruit .then go to the radio tower get to the top and face the leader of the operations if you win you get the key to the secrete place above the magnetic train station
go to the underground tunnel in goldenrod there will be a team rocket grunt talk to him and he will give you a team rocket suit(sweet). go to the radio tower but before you do make sure your Pokemon are healed because your rival and rocket grunt will fight you. make your way up fighting every grunt then executive proton will be dressed up as the director he will fight you he has 5 koffings and 1 wezzing then he will give you a useful item and tell you something important then there are more grunts and executives on the way.when you beat archer whos at the top the director will give you a silverwing in soul silver or a rainbow wing in heart gold he will also tell you that you need another item to face lugia or ho-oh
In which city? In celadon, go to the game corner and press the button behind the rocket poster. Then head through the underground maze...simple beat all gyme leaders and you will face giovanni at the last gyme
Get the clear bell as a gift from the Radio Tower Director (from Goldenrod) after defeating Team Rocket. Go to the Tin Tower entrance and you will later face three sages that you must battle. You meet Suicune once you enter the tower.
go to dragon den and get elders approval catch lugia and face the Pokemon league
in the galactic warehouse
This was a problem that I was having a lot when I played the Johto games. after u beat pryce and get team rocket out of the radio place, go to goldenrod city in the radio tower and battle team rocket in the tower. be careful, in the tower, you will have to face some old rocket rivals like adriana, proton, and petrel. after you beat archer, who will standing on the observatory floor, in the tower, you will then be able to pass the guy. (p.s the ragecandybar in absolutley useless)
In Johto!! their are Two Times this happens1) Mahogany Town2) GoldenRod CityMahogany Town - First goto The lake of Rage, talk to the guy with the Drangon Pokemon and say, 'yes' then come back south to Mahogany town - Go into the small shop - The guy with the Drangon Pokemon should be inside - now he will push a Golden Box thing - thus discovering an underground cave - Explore the cave and turn off the lazers and soon find yourself head-to-head with the Boss one you have the two passwords - follow his Pokemon and he'll open a thing now do what the dragon guy says battle a buch of stuff and head back to the exit!GoldenRod City - This is different firstly - In GoldenRod City go to the Game's Cornor, if you head west you'll come across an Alleyway go to the very bottom and you will notice a small building - enter it. Once went down the stairs you May have to face on Scientist - when finshed head right (East) Enter the Locked door and go down the steps - Finsh the Maze and go through the door then make your way throught the maze type thing - aviod as many members of team rocket as possible and in the center you will find the Radio guy - Notice that your under the GoldenRod Department StoreNO KANTO -- YOU CAN FIND TEAM ROCKET GRUNT LOOK HARDER!!
on six island there is an area called dotted hole. when you get to it use cut on the door and follow the braille directions. when you get to it a scientist appears and takes it saying it will sell it to team rocket then runs off. go to the rocket warehouse and when you get to and beat the second admin you will have to face off his team. they are all level 45-50 so beware and good luck!
