Master Lock® has a new Deadbolt that operates like any 3 digit dial
combination lock. The NightWatch™ Combination Deadbolt, combines the keyed entry
security of a deadbolt with the keyless flexibility of a safe lock. The
NightWatch™ Combination Deadbolt installs like a standard deadbolt with just a
Phillips screwdriver, and when the patent-pending NightWatch™ feature is
engaged, the lock cannot be opened from the outside by any means; key, picking,
bumping etc.
Let's take a step by step look at how this lock works and how to install it.
