Single Cylinder Deadbolt for Exterior Doors

The Kwikset 660 is a single cylinder deadbolt designed for front entry doors that require a high level of security. It uses a key on the outside and a turn piece on the inside. The lock carries a Grade 3 BHMA certification for security, durability and finish. Microban antimicrobial protection is built into the finish.

SmartKey Re-Keying and Adjustable Latch

SmartKey Security technology protects against advanced break-in techniques and allows the owner to re-key the lock in seconds without a locksmith. The adjustable latch backset fits both 2-3/8" and 2-3/4" preparations with a simple twist during installation. It fits standard doors 1-3/8" to 1-3/4" thick. All mounting hardware is included for a screwdriver-only installation.

Upgrade from Non-Rekeyable Deadbolts

This deadbolt replaces fixed-key cylinders where lost keys mean replacing the entire lock. The jump is worth it when you need to change key access quickly after a move, a lost key or a change in household members. It is not suited for doors that need double-cylinder operation or electronic keyless entry. The traditional satin nickel style matches classic home décor.

Questions about this item

How long does the Grade 3 BHMA certified deadbolt last under constant locking and unlocking?

Does the metal cylinder or latch generate noticeable heat or noise during all-day operation?

The deadbolt is a purely mechanical device with no motor or electronics, so it produces no heat and only the normal click of the bolt and key turning.
