Then here's what we'll do.
Vera-Kin and Kiu can move to the fire exit, but if questioned because Kiu isn't very sneaky (though I want him to try rolling the stat), Vera-Kin uses her Mind Tricks to get them off of us. Then, Kiu can open the fire exit, and the two can slip inside. Then, R3-U9 can station himself at the control panel to appear to open the main entrance himself, while Vera-Kin and Kiu actually open it from within. That way, nothing suspicious about R3.
Okidokey, sounds ok. You make some good rolls, too and get to the fire exit just fine. Two minutes later and you are inside. The warehouse is large and gloomy, but your senses take care of that.
R3 trundles dutifilly over to an access point and starts to access data. He starts to emit a few bells and whistles, which you guess means that he wants to know exactly what you want.
"Excellent work, R3, now lets upload those schemactics to my datapad and then we can be on our way..."
We'll take the fire exit to go the other way out of the droid storage, having Kiu silence any alarms with Fix-It if need be, then head for bay 487c, and from there, to the security room that we should be able to find on the schemactics.
