you get the quick charger
The scooter has a battery, but it needs charging. Go to MacGuffin's and get one of the new devices that is supposed to quickly charge things.
The word is "frost."
The password to the scooter is "frost."
You only have the scooter when you are chasing the security cart around the mall. You use the password (frost) to get it from the Manager's Office, and charge it with the charger device from MacGuffin's. After you chase down the cart, Eddie the snake has the scooter (and may still have it when you leave).
The code for the scooter is "FROST."
When you are chasing the robber in his stolen security cart, Gus suggests you get the scooter that is in the office. Use the password (frost) to get it. Go to MacGuffin's to get one of the quick chargers to charge the scooter's battery. Leave the office with the scooter, and go to the escalator on the far side of the atrium.
After you get the scooter, charge it, and chase the cart into the fountain, head back to PrintFax and click on the first copy machine. Press "menu" and select the last scan.
The security cart is still driving around the atrium while you get the charger from MacGuffin's but may not be there when you exit on the scooter. Try driving to the left side escalator, where you will eventually go to trap him. If he doesn't appear, go left into the mall, then come back and the chase may refresh.
You don't. You have bigger problems. Besides, he might bring it back.
The combination on the safe is 6723. The password code to open the scooter cabinet is "frost."
No one knows, and you do not have to find him. Eddie will come back to help out in the end.
Barely. Eddie the snake gets to ride it. The only time you use it is in the job testing by the manager, and when you have to catch the crook driving the security cart. Gus will give you the password to get the scooter from the Manager's office, and you can charge its battery with the quick charger from MacGuffin's. Once you chase the cart down the escalator, you find that you were tricked by a training robot. That's when Eddie makes off with the scooter.
