How do you catch Rayquaza when the door is closed?

This question is a bit tricky! It seems like you're referencing a specific event or game, but the information isn't clear enough to give a precise answer. Here's why:

* Rayquaza in different games: Rayquaza appears in multiple Pokémon games. Its location, catching method, and whether a "door" is involved vary depending on the game.

* "Door" ambiguity: The term "door" could refer to a literal door in a game, a barrier preventing access, or something else entirely.

To help me answer your question, please provide more information:

* Which Pokémon game are you playing? (e.g., Pokémon Emerald, Pokémon Omega Ruby/Alpha Sapphire, Pokémon Legends: Arceus, etc.)

* What "door" are you referring to? Is it a physical door in the game, a barrier to accessing Rayquaza, or something else?

* What is your current progress in the game? Are you at a specific point in the story?

Once I have more context, I can give you a more accurate and helpful answer. 😊
