Wow, I wish it were that easy to renew your license in Kentucky! We are forced to actually go to the DMV, no online nor mail option, every four years! You aren't required to submit a stool sample when renewing, however, our current license is good enough. If you lose your license, it's a different story, though. Then I think you are required to present a birth certificate, social security card, and piece of mail addressed to you. KY may also require another form of id, when replacing a lost license, but I can't remember.
