I have two dead bolt key pads on my house, they are tied in with my security system, if the batteries go dead you can unlock them with a key, you can also set up multiple 4 digit codes to allow access to your home for different people, when they punch in the appropriate code it also disarms the alarm system.
All this can also be activated from your smart phone plus more controls in and around your house including the thermostat etc.
