i am in the military base and i've opened the hanger door, but i dont know were to get the passcodes from anyone know?

anyone?

there's lots of military bases, lots of hangar doors and lots of passcodes. Need to be a little more specific. what planet are you on?

Telos I presume, just before you go to the reactor there's a big room, with two office type rooms at either sides, one has a bunch of droids in, defeat them and there's a door to be unlocked, inside is a cylinder, open that and the codes are in there.
