This is from my walkthrough. Is this where you are stuck at? Left me know if this helps at all, or if you want any more help.

SPOILER ALERT
PICK UP the flask of blue liquid near the steps where you entered. Go through the gate that is middle-right of the screen. Walk onto the elevator. When it breaks, USE the cable on the elevator. TALK TO the tramp and be polite to him. Give him your blue flask and he will give you an ID pass.
Walk back beside the elevator and cable. JUMP on to the cable. Now USE your droid with the elevator controls at the top and you'll find yourself back on the road. Head north along the road to find yourself in Kaleev Way. Go up the esculator, then head right. Go up this esculator as well. There is a blue dispenser unit on your left. INSERT your blue ID car, then click on "PRESS TO ORDER".
