On Wednesday we did a live demo for our Princeton Computer Science colleagues of the vote-stealing software described in our paper and video. Afterward, Chris Tengi, a technical staff member, asked to look at the key that came with the voting machine. He noticed an alphanumeric code printed on the key, and remarked that he had a key at home with the same code on it. The next day he brought in his key and sure enough it opened the voting machine.
This seemed like a freakish coincidence — until we learned how common these keys are.
Chris’s key was left over from a previous job, maybe fifteen years ago. He said the key had opened either a file cabinet or the access panel on an old VAX computer. A little research revealed that the exact same key is used widely in office furniture, electronic equipment, jukeboxes, and hotel minibars. It’s a standard part, and like most standard parts it’s easily purchased on the Internet. We bought several keys from an office furniture key shop — they open the voting machine too. We ordered another key on eBay from a jukebox supply shop. The keys can be purchased from many online merchants.
