Benefits & Use Cases

The Kwikset 660 Deadbolt is engineered for front entry doors in homes where security, ease of use, and aesthetic appeal are equally important. Its single-cylinder design offers straightforward operation—lock or unlock from the outside with a standard key, then rotate the interior thumb turn for quick egress inside your home. This makes it particularly suitable for families, seniors, and anyone who values both safety and convenience.

One of the standout advantages is the SmartKey Re-key System. Unlike traditional locks that require a professional service to change keyways, you can fully re-key this lock in minutes using just your existing key and the provided adapter. This means no waiting for appointments, no extra fees, and complete control over who enters your home. It’s an excellent solution for new homeowners, landlords managing multiple units, or anyone concerned about unauthorized access due to lost or duplicated keys.

The inclusion of BumpGuard technology adds another layer of defense by resisting common break-in methods such as lock bumping—a technique often used by thieves to rapidly open pin-tumbler locks. Combined with the solid brass construction and durable steel components, this deadbolt provides reliable protection against forced entry.

The Satin Nickel finish not only looks modern and clean but also offers practical benefits. It’s resistant to smudges, scratches, and corrosion, ensuring the lock maintains its polished appearance even with daily use. Whether installed on a traditional wood door or a contemporary metal entryway, this finish blends seamlessly with most home exteriors.

Homeowners appreciate the sturdy feel and dependable performance of the 600 Series. Built to last, this deadbolt withstands harsh weather conditions, repeated use, and everyday wear-and-tear without compromising functionality. The Microban treatment further enhances hygiene by reducing bacterial buildup on high-contact areas like the knob and faceplate—making it a thoughtful choice in shared living spaces.

Important Notes

Before purchasing, ensure your front door meets the required thickness specification of 1 3/8 to 1 3/4 inches to guarantee proper fit and function. Measure carefully if upgrading an existing lock or installing on a newer door frame. While the Microban protection helps maintain surface cleanliness, regular wiping with mild soap and water is still recommended for optimal hygiene.

No additional tools are needed for re-keying thanks to the user-friendly SmartKey system. Simply follow the three-step process outlined in the included instructions—no locksmith required. However, installation may involve removing your current deadbolt first, so having basic hand tools on hand is advisable unless opting for professional setup.
