Crazy cousin Laszlo will tell you that you need a scanner to find out who changed the garage code. You will receive the blueprints for the scanner. Use the teleport pad to get into the storeroom. Here you will see your first gadget, the Disassembler. You will need this to grab parts for the scanner you have to build. Find a way up the crates to reach the Disassembler (there are various ways to reach it).
Once you grab it, tutorial windows on the Disassembler and targeting will pop-up. Practice targeting and using your newly acquired gadget on the crate. Keep on disassembling stuff in the warehouse until you have 10 of each of the required components.
When you have 10 of each component, head back up the tube to the Lab and use the Transmogrifier. Will all the necessary components, you will be able to make the scanner. Once you make it, a tutorial pop-up will on the scanner will appear. Cousin Laszlo will then tell you that he will reward you for any interesting scans you may find (strangely, he uses them in his paintings). Your first scanning target will be Laszlo himself. Go ahead and scan the other things in the Lab: The Bird, The Organ, Transport Tube, The First Invention, The Cupid, Carl, Machine of Possibilities, and the Transmogrifier. Now that you have the scanner, you can now check out the garage keypad.
