Shepherd turns your existing deadbolt into a touch-activated lock. When your authorized smartphone or Bluetooth device is close to the lock, a simple touch will unlock it. So you can easily get inside even if your arms are full. Easily lock or unlock your home from the inside - no approval needed. Simply touch the sleek and elegant Shepherd Lock, mounted as a retrofit where the original thumbturn is located on the inside of your door. Additionally, there’s a manual backup thumbturn inside Shepherd. We value your privacy and will never ask for a fingerprint. Shepherd Lock approves or disapproves of users based on the Bluetooth signal from their smart device. Give or rescind access to anyone anytime. All you need to do is download the app.
