I had an older version of this that didn't include my newer vehicle, and it can't be updated. I confirmed this one did have my car before ordering. You don't need any instructions, just plug into the OBD2 and follow the instructions. Some of the prompts can be a bit cryptic, but it's not difficult to figure out. I had my new key (must be cut and useable) programmed in less than two minutes, start to finish, for the low cost of this device, and I can program other keys in the future, instead of paying my dealer $175 for just one key. Great investment.
