How do you unlock the gym leaders door in Petalburg city in Pokemon ruby?

Answer 1

you have to keep looking in the trash cans if you find one key the other key should be in the trash cans next to it. ------- It's trial and error. I got through with the cans in the bottom right and top left corners.

Answer 2

The gym is made up of an "invisible" maze. If you look very closely, you can see where the walls are. You may have to face a few of Koga's underlings in the process of trying to figure it out, but its not terribly hard at all.

Answer 3

You have to go to the sky pillar and then awaken rayqausa but talk to stven first then go find Wallace like steven asked you to then talk to him and say to Wallace skypiller when he asks you then go to route 131 then there should be a pile of rocks on your left side then surf until you see a path and go in then there should be a cave enter it and Wallace will talk to you and bring a lot of max repels and make sure you have a Pokemon who knows fly. Hoped i helped :)
