yes if you go to map 273 in renas map editor and go to warp editor you will see theres 4 under door witch means 4 must be wraith key so then you go to pub editor and look at wraith key and under SP1 you will see a 4 witch means every door you put a 4 on will need a wraith key to open it
to make a new key the TYP must be 9 and the SP1 has to be the same id as the door
