The Haven Smart Lock is one of the more unique smart locks on the market. When it comes to protecting your home and your family, you want only the best. Install it inside it on the floor near the bottom of your door and you have total control via a mobile app or a key fob. This smart look is made of military-grade materials and it works by raising a wedge at the base of your door that blocks entry, absorbing the force of an attempted break-in. You can step on a pedal to lock it from inside.
