Actually, the way Dtroid said doesn't work. for some reason when you move unlocked doors to some place, the door doesn't work anymore. I tested it in my unfinished LDC entry and it didn't work.
Yep, I tested it, every time I press'd the switch, the door with a lock moved off, but the unlocked door disappeared.
BUT,,, I can make an locked area, with the unlocked door on it, and when I press the switch, the locked area opens, revealing the unlocked door!
*applauses*Anyway, thank you guys, because the delta orb idea is good too
