Special Features of the Master NightWatch® Deadbolt

Suburban homes in twilight

The NightWatch deadbolt provides extra nighttime security and protection. That’s because it’s the only deadbolt that prevents an intruder from entering your home, even if they have your key. When the NightWatch feature is engaged, the deadbolt can only be locked or unlocked from inside the home. All NightWatch deadbolts also feature BumpStop™ Advanced Cylinder Technology to resist bump attacked.
