How can you get through the doors in Pokemon mansion in Pokemon Diamond and Pearl?

If you're asking about the two doors on either end of the inside of the mansion, it's impossible to walk through them even with an action replay walk/run anywhere cheat. Ask http://wiki.answers.com/Q/How_do_you_unlock_pokemon_mansion_doors_whee_the_ladys_are_standing, I have answered that question, I just don't have time to answer this one.
