Notice that when you reach the bottom of the conveyer belt, there is an enemy that flies into you (not "fly" by "flies" I mean, runs into you extremely fast). You'll notcie that above this enemie's head there is the key card you are looking for. This took me some time to figure out actually. Use your Z Knuckle to take the crad from the enemy (by killing it of course). Be careful as you work your way up to the locked room, the enemies along the way can knock the key card from you (If I remember correct that is). Once you get to the door, just stand next to it and throw the card into the door, and....... Presto. I'm can't remember what is inside though, I believe it is a recipe item. I haven't played this game in a while.
