Kwikset 660 Deadbolt Lock

It features Kwikset’s SmartKey Security technology, which protects against common break-in techniques and enables rapid re-keying by homeowners in seconds. The lock is designed for exterior use, with a single-cylinder deadbolt that provides keyed exterior access and interior turn-piece locking. The hardware kit includes all components needed for a do-it-yourself installation with a standard screwdriver. Ideal for homeowners seeking an affordable upgrade to current exterior doors without sacrificing security.
BESTTEN Keyed Alike Exterior Door Knob and Deadbolt Combo
This BESTTEN combo set pairs a keyed-alike entry door knob with a single-cylinder deadbolt, using the same key for both. The kit simplifies access control on exterior doors by reducing key management. Installation notes indicate preinstalled machine screws in some models—if present, remove them before mounting. The KW1 keyway supports standard key profiles. The set is designed for ease of use, offering secure entry with a single key for both hardware components, making it a convenient choice for homes and rentals that prioritize straightforward access.
Amazon Basics Exterior Door Knob With Key Lock and Deadbolt
The Amazon Basics exterior set combines a durable brass body with a steel interior and an adjustable latch that fits doors with backsets from 2-3/8 to 2-3/4 inches. The kit includes four keyed-alike keys and relies on a KW1 keyway for compatibility with common key profiles. A rounded steel faceplate and strike, along with a zinc alloy latch bolt, provide solid construction for exterior doors. This option suits budget-conscious buyers seeking a reliable, standard-entry system with straightforward maintenance.
BESTTEN Single Cylinder Deadbolt
This BESTTEN single-cylinder deadbolt emphasizes industrial-grade all-metal construction and hardened steel components, providing robust security for front and garage doors. The matte black finish is wear-resistant and designed for high-traffic environments. It pairs well with BESTTEN door levers and knobs when a cohesive look and reliable performance are required. The design focuses on durability and consistent operation in demanding settings while maintaining a classic, low-profile appearance.
PRIME-LINE U 9970 Deadlock
The Prime-Line U 9970 Deadlock offers a jimmy-resistant design that helps prevent forced entry by spreading of door frames. It features a cross-bolt locking mechanism and comes with a brass finish that suits many exterior doors. The unit is surface-mounted and adjustable for doors 1-3/8″ to 2-3/8″ thick, compatible with left- or right-handed doors. Durability is achieved through a diecast metal body, providing reliable security for homes and small offices while remaining relatively easy to install with standard tools.
Buying Guide: Key Purchase Considerations and Comparisons
When choosing a deadbolt, consider the following factors to ensure you pick a model that fits your door and security needs:
- Security level and mechanism: Keyed-entry deadbolts provide robust protection, while smart-key or keypad options add convenience and rekeying capabilities. Evaluate which approach aligns with your security goals and maintenance preferences.
- Material and build quality: Look for solid metal construction, hardened components, and anti-drill or anti-pick features. A durable finish (e.g., matte black, satin nickel) helps resist corrosion and wear.
- Lock alignment and backset: Most exterior doors use a standard backset of 2-3/8″ or 2-3/4″. Ensure the lock you choose matches your door’s backset and bore size for a proper fit.
- Installation and compatibility: Some models are designed for quick, do-it-yourself installation, while others may require professional help. Check included hardware and compatibility with your door type (wood or metal, single or double door, handedness).
- Key management: If you have multiple doors, consider keyed-alike options to simplify access with the same set of keys. If you share access with guests, a smart-lock or keypad can be advantageous.
- Maintenance and replacement: Choose a lock with available replacement parts and straightforward maintenance to extend its service life without excessive cost.
- Aesthetics and finishes: The lock’s finish should complement your door hardware and exterior appearance. Popular choices include satin nickel, brass, and matte black.
- Smart features vs. traditional: SmartKey or keypad options provide convenience but require batteries and periodic code management. Traditional keyed deadbolts offer reliability with minimal upkeep.
In summary, the Kwikset 660 provides SmartKey rekeying and solid security for exterior doors, while the BESTTEN, Amazon Basics, and PRIME-LINE options cover a range of budgets and installation scenarios. For homes needing a combination of knobs and deadbolts, consider keyed-alike sets to streamline access. Always verify compatibility with your door’s backset and thickness before purchasing.
