We have had this lock for a couple years. My husband and I are not very handy so thought it prudent to hire a locksmith and save the marriage. I have the program on my iPhone and he uses the fob. Since both of our cars turn on with the push of a button, we have no need to have our keys in our hand when entering the house from the garage. The Kevo lock is perfect for us. We have set up the kids with access on their iPhones and I rave about the convenience all the time. Get one, you'll love it!
