Secure your home with the Kwikset 660 single cylinder deadbolt in a Venetian Bronze finish. Kwikset calls the 600 series the largest-selling deadbolt in America, and this version adds SmartKey Security, which lets you re-key the lock yourself in seconds without removing it from the door - ideal for new homeowners, rentals, or anytime you need to control who holds a key. A patented side-locking bar replaces the conventional pin-and-tumbler cylinder, and two steel balls set into the cylinder face improve drill resistance.
