Choosing a Kwikset Single Cylinder Deadbolt

A single-cylinder deadbolt is keyed from the exterior and uses a thumbturn on the interior. This common residential configuration provides key-controlled outside access while allowing the deadbolt to be operated from inside without a key.

Measure the existing preparation before replacement. Confirm backset, cross-bore and edge-bore dimensions, door thickness, bolt faceplate or drive-in configuration, strike size, and the area covered by the exterior and interior trim. Adjustable bolts can support more than one backset, but the exact product should be checked.

SmartKey Security is included on selected models and allows compatible cylinders to be re-keyed using Kwikset's specified process. Other models may use traditional cylinder formats. Verify SmartKey compatibility and the keyway if the deadbolt must coordinate with existing Kwikset locks.

Some products in the category add electronic access or are sold as combination packs with a keyed knob. Review exactly what is included, along with battery or programming requirements for electronic models and the additional latch preparation required for combo packs.

After fit and lock format are confirmed, compare trim profile and finish with the knob, lever, handleset, hinges, and other entry hardware.
