you need to be the evilest you can be, first of all. next when you go and fight your way through the hordes of dark jedi and sith, before Darth Malak, you come to this door with 3 dark jedi inside. you also need 23 spikes or very good computer skills. go to the computer terminal and they should be there. you could also do the reverse, when you're good, and get master jedi robes. hope this was helpful.
