You cannot trade Key Items from other games to another because i you say, traded the Blue Orb from Saphire to Ruby, and went into The Cave Of Origin, then you would screw the game up, and possibly break it to being unusable!
As far as I know there is no code for key items.
Firstly, you have to go to Goldenrod City. Go on the very west of Goldenrod City where there is a really big building. That is called the GTS. You can trade there. *This answer has been approved and written by Wikia Lord.
