Along comes this post by Ed Felten reporting that they have found that
The access panel door on a Diebold AccuVote-TS voting machine — the door that protects the memory card that stores the votes, and is the main barrier to the injection of a virus — can be opened with a standard key that is widely available on the Internet...Earlier Diebold post.
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.
Using such a standard key doesn’t provide much security, but it does allow Diebold to assert that their design uses a lock and key. Experts will recognize the same problem in Diebold’s use of encryption — they can say they use encryption, but they use it in a way that neutralizes its security benefits.
