Kwikset's Double Cylinder Deadbolt offers ANSI Grade 3 security. It has an adjustable latch to fit 2-3/8 inch or 2-3/4 inch backsets; and it will fit door thicknesses up to 1-3/4 inches. Operated by a key on the exterior and the interior of the door. It has a lifetime mechanical warranty from Kwikset for tough, effective protection at an affordable price.

Double Cylinder Deadbolt: Deadbolt thrown or retracted on both the inside and the outside by a key. Since it is keyed on both sides of the door, it is typically used on entry doors with glass near the lock to prevent thieves from breaking the glass and unlocking the deadbolt using a thumbturn.

This Smartkey Kwikset Lock offers connivence and security. It allows you to re-key the lock yourself without removing from the door; this mean you will be able to key all your SmartKey locks to one Kwikset key.
