The Comfhouse satin nickel model is best for buyers who want listed fit dimensions and included keys; the Kwikset 660 is a better fit for shoppers seeking re-keying features; and the Schlage option is suited to buyers prioritizing its stated BHMA rating. The products below compare finishes, features, and available fit information.

Comfhouse Satin Nickel Single Cylinder Deadbolt
This keyed deadbolt has a key-operated exterior and an interior thumb turn. Its listed features include three nickel-plated brass keys, a KW1 keyway, and a five-pin brass cylinder. The manufacturer describes the stainless-steel deadbolt as anti-rust and durable, and the zinc-alloy latch bolt as tested for more than 250,000 cycles.
Best for: Buyers who want an included fit range and a traditional satin nickel finish. The adjustable latch supports 2-3/8-inch or 2-3/4-inch backsets, and the stated door thickness range is 1-3/8 to 1-3/4 inches. Limitation: Confirm those measurements match your door before buying.
Kwikset 660 Deadbolt With SmartKey Security
The Kwikset 660 is a single cylinder deadbolt with an interior turn piece and exterior key operation. Its listed SmartKey Security feature is designed to let owners re-key the lock themselves. The product information also says installation can be completed with a screwdriver and that hardware and directions are included.
Best for: Buyers who value the option to re-key without replacing the lock. Choose this if DIY installation guidance and included hardware matter to you. Limitation: The supplied product details do not state backset or door-thickness dimensions, so check the product information against your door before ordering.
Comfhouse Matte Black Single Cylinder Deadbolt
This Comfhouse model shares the listed functional and fit features of the satin nickel version, but has a matte black finish. It includes three nickel-plated brass keys and a five-pin brass cylinder with a KW1 keyway. The key operates the exterior side, while a thumb turn operates the interior side.
Best for: Buyers who want a matte black deadbolt with stated standard-door dimensions. Its adjustable latch accommodates 2-3/8-inch or 2-3/4-inch backsets, and the stated door thickness range is 1-3/8 to 1-3/4 inches. Limitation: The darker finish is the key distinction from the Comfhouse satin nickel model; verify that it suits your existing hardware.
Kwikset Peralta Handleset And Deadbolt
The Peralta is a front-door handleset rather than a standalone deadbolt. It is listed for exterior doors with two bore holes and includes an exterior keyed deadbolt, keyed grip, interior lever, and interior turn piece. The product information describes two interior locking components and includes SmartKey Security for re-keying.
Best for: Buyers replacing front-door hardware who need a coordinated grip and deadbolt set with two locking points. Choose this instead of a deadbolt-only product when you also want the handleset and interior lever. Limitation: It is intended for a two-bore-hole door; check your door layout before selecting it.
Schlage Satin Nickel Single Cylinder Deadbolt
This Schlage deadbolt has a satin nickel finish and premium metal construction, according to its product description. The listed feature is a BHMA Grade 1/AAA rating for security, durability, and finish, which gives shoppers a stated rating to compare when evaluating locks.
Best for: Buyers who prioritize the product’s stated BHMA rating and a satin nickel appearance. Limitation: The supplied features do not specify fit dimensions, included keys, or re-keying details. Confirm those requirements before purchase if they affect your choice.
Buying Guide: How To Choose A Single Cylinder Deadbolt
Does your door match the lock dimensions?
Check the door thickness and backset before ordering. The backset is the distance from the door edge to the center of the lock hole. Among these options, the two Comfhouse deadbolts list a 2-3/8-inch or 2-3/4-inch adjustable backset and a 1-3/8- to 1-3/4-inch door thickness range. The supplied details for the other products do not list those measurements.
Do you need a deadbolt only or a complete handleset?
A standalone deadbolt is appropriate when you are replacing only the deadbolt. The Kwikset Peralta is a broader hardware set with a keyed grip and interior lever as well as a deadbolt. Its two-bore-hole requirement makes door layout an important check before buying.
Would re-keying be useful?
SmartKey Security is listed for the Kwikset 660 and Peralta. The feature is described as allowing owners to re-key the lock themselves. If this matters, compare that feature directly with other priorities, such as finish, fit dimensions, and whether you need a complete handleset.
Which finish and stated features matter most?
Choose satin nickel for a conventional metal look or matte black if you want the darker Comfhouse finish. For a product with a stated BHMA rating, consider the Schlage listing. Compare only the information provided for each model, and verify any missing specifications before purchase.
