Kwikset calls the 600 series the largest-selling deadbolt in America: tough, effective protection at an affordable price. This is the standard pin-and-tumbler version of the 660 single cylinder deadbolt, finished in Venetian Bronze, with a full 1" throw for front- or back-door security. It does not have SmartKey re-keying - see the SmartKey version of the 660 if you want to re-key the lock yourself.
