Gate

In Kingdom Hearts, the Keyholes were sealed, leaving no way to travel between each world. About a year later, the Heartless found another method of traveling between worlds, creating their own Gates. A good portion of the Gates are revealed in Kingdom Hearts II.

The Gates are opened by the item in question (see below) is surrounded in light and then a huge gust of wind blows. The item in question reveals the keyhole to a route and then Sora spins his Keyblade and unseals the Gate. Sora, Donald and Goofy continue on their adventures there after with the new route opened.

It's likely that Worlds within worlds do not have Gates, because the outer world's Gate also serves as their own. This could be true for Space Paranoids, 100 Acre Wood, and Timeless River.
