If you mean the guy blocking you because of the blackout, just follow the storyline. You do NOT need any special Pokémon or pass or ticket or whatever to get inside.
If you’re asking about Flint blocking the gym, you’ll have to go to the lighthouse on the southeast side of Sunnyshore first, then talk to Volkner. He’ll go back to his gym and you can enter.
You need to get dialga ( in diamond) palkia (in pearl) and giratina ( in platinum) once then he will be gone
You have to go to Sunnyshore City and battle the Blonde haired guy if you haven't got passed the guy you to capture Palkia/Dialga then he says the power is back on

It doesn't have a point the guy just says it.

Battle Dialga or Palkia at Spear Pillar and the guy blocking the road will leave.
In fact, there is no other way to Sunnyshore city other than that of going to Spear Pillar and coming back. Then, he is gone.
