The YRD136-ZW2-619 from Yale is a Pro Pushbutton Deadbolt Z-Wave Key Free, Satin Nickel. The Yale Pro is a key-free deadbolt with Z-Wave Plus built-in, available in touchscreen or keypad models. It replaces a standard deadbolt in minutes using just a screwdriver and can be added to dozens of Z-Wave smart home and alarm systems with one-touch enrollment. The lock is 100% key free so it can't be picked and there are no keys to lose. To prevent lockouts due to dead batteries, there is a 9V battery terminal located below the keypad. The lock has a backlit keypad that wakes with a touch and has numbers that won't wear off. It's backed by a lifetime limited warranty on finish and mechanics and a one-year warranty for electronics.
