It is a adapter, for programming keys and remotes. It does hook up to a hand held comp. looks like a black box. LOL when I was a locksmith I had one. The real sad truth is, i could make a key for almost all 8 cut hondas in less that 10 sec. Chrysler products are even easer..... Keyless ride is a company that makes remotes, keys, and programing equipement.
