A black door knob and deadbolt set can give an entry door a coordinated look while providing two ways to secure it: a keyed lock at the handle and a separate deadbolt. The right choice depends on your door’s measurements, how many doors you need to outfit, and whether you prefer a knob or lever. These five options range from basic keyed-alike sets to models with stronger stated security features.

Our Picks: Best Black Door Knob And Deadbolt Set reviews
1. Amazon Basics Coastal Knob and Deadbolt: A Simple Keyed-Alike Set
This Amazon Basics set pairs a keyed entry knob with a deadbolt in a matte black finish. The two locks use the same key, and the package includes four brass keys. That makes it a practical pick for a front or side door when you want a coordinated set without a large multipack.
The latch adjusts to a 2-3/8- or 2-3/4-inch backset, and the set is specified for doors 1-3/8 to 1-3/4 inches thick. Its steel internal structure, stainless steel body, zinc alloy latch bolt, and steel faceplate and strike provide a clear materials summary. Installation instructions are included, and the set has a one-year limited warranty.
Compared with the Schlage, this is a simpler option without the same stated security certification or reinforced strike details. It also does not offer the rekeying feature listed for the Kwikset. Check your door’s bore and latch measurements before ordering; the product data gives a 2-1/8-inch lock body hole and a 1-inch latch hole.
Pros:
- Knob and deadbolt are keyed alike
- Includes four keys
- Adjustable backset fits common door preparations
- Installation instructions and a one-year limited warranty are included
Cons:
- Does not list a rekeying feature
- Warranty is shorter than the lifetime warranties listed for Kwikset and Schlage
Verdict: Choose this set for a basic, coordinated black entry lock with shared keys and standard adjustable fit.
2. BESTTEN Two-Pack: A Convenient Choice for Two Doors
This BESTTEN package is designed to cover two entry doors with matching knob-and-deadbolt sets. The product information specifies six keys that work across the sets, which can simplify key management for a front and back door or another pair of compatible doors.
The stated fit is for doors 1-3/8 to 1-3/4 inches thick, with a latch adjustable between 2-3/8 and 2-3/4 inches. The listing describes an all-metal construction and says the locks are not rekeyable, so plan on using the supplied key arrangement rather than changing the cylinders later.
There is an important detail to verify before buying: the supplied description mentions both satin nickel and matte black finishes. Since the title does not specify a finish, confirm the selected listing option and product images show the black version you want. The instructions also say the handle’s machine screws arrive preinstalled and should be removed before installation.
Pros:
- Includes two knob-and-deadbolt sets
- Six keys are described as keyed alike
- Adjustable latch and common door-thickness range
- All-metal construction is specified
Cons:
- Finish details in the supplied product information conflict
- Not rekeyable, according to the listing
Verdict: This is worth considering when you need two sets, but confirm the finish and keying details on the listing before placing an order.
3. Kwikset Casey: A Lever Set with SmartKey Rekeying
The Kwikset Casey combines a keyed entry lever with a deadbolt, rather than a round knob. Its matte black finish suits shoppers who want the same dark look but prefer a lever handle. The product is intended for exterior doors and is also described for use in apartments, condos, rentals, and other residential settings.
Its main distinction is SmartKey Security, which the product information says lets you re-key the lock yourself. That can be useful if you need to change access without replacing the whole lock, though you should follow the manufacturer’s instructions for the process. The latch adjusts between 2-3/8 and 2-3/4 inches, and it fits doors 1-3/8 to 1-3/4 inches thick.
Compared with the Amazon Basics and BESTTEN picks, the Casey offers the listed rekeying feature, but it is a lever rather than a knob and the product data does not provide a security grade. It is backed by a lifetime mechanical and finish warranty according to the supplied information. Confirm that a lever is suitable for your household and local requirements before choosing it for an exterior door.
Pros:
- SmartKey feature allows rekeying, according to the product information
- Adjustable latch fits two common backsets
- Matte black finish and lever-handle design
- Lifetime mechanical and finish warranty is listed
Cons:
- Uses a lever, not a knob
- Product data does not specify a security grade
Verdict: Pick the Casey if rekeying flexibility and a lever handle matter more to you than having a traditional knob.
4. Brotima Three-Pack: Shared Keys for Multiple Entry Points
Brotima’s package includes three keyed entry knob-and-deadbolt sets, making it a useful option when you are replacing locks on several doors at once. The listing says the locks are keyed alike, so one key arrangement can serve multiple sets. That may be easier to manage than carrying separate keys for each entry.
The product description states that the set meets ANSI Grade 3 standards and describes a single-cylinder deadbolt with an anti-sawing bolt. It also lists stainless steel construction and a corrosion-resistant matte black finish. The latch adjusts to either a 2-3/8- or 2-3/4-inch backset, and the set is described as reversible for different door orientations.
Those listed features make this a more feature-detailed multipack than the Amazon Basics set, but the product information does not provide a door-thickness range or the same detailed bore measurements. Check those dimensions and verify the exact contents for each set before buying. A keyed-alike arrangement is convenient, but shared keys also mean each included key can operate the compatible locks in the pack.
Pros:
- Three knob-and-deadbolt sets in one package
- Keyed-alike design for managing several doors
- ANSI Grade 3 standard is claimed in the product description
- Adjustable backset and reversible installation are listed
Cons:
- Door-thickness range is not included in the supplied details
- Confirm the pack contents and fit measurements before ordering
Verdict: Consider Brotima when you need three matching sets and shared keys, provided its door-fit details match your doors.
5. Schlage Georgian: A Strongly Specified Set for an Exterior Door
The Schlage set pairs a Georgian-style knob with a single-cylinder deadbolt for an exterior door. The deadbolt is operated by key from outside and a thumbturn from inside, while the lower handle can be unlocked from inside. The product includes two keys and is designed to fit both left- and right-handed doors.
Its listed security features set it apart from the simpler options here: a one-inch deadbolt, hardened steel spinning pin, anti-drill plates, anti-pick pins, and an integrated strike reinforcer with three-inch screws. The product also states an AAA BHMA rating for security, durability, and finish. Those features are useful points of comparison, but a lock is only one part of a secure door; the door, frame, and installation matter too.
The universal latch adjusts to a 2-3/8- or 2-3/4-inch backset, and the set fits doors 1-3/8 to 1-3/4 inches thick. Self-aligning screw holes are intended to simplify installation. It comes with a limited lifetime mechanical and finish warranty, with the supplied warranty information specifying that coverage applies to purchases shipped from and sold by Amazon or Buildcom.
Pros:
- AAA BHMA rating is specified for security, durability, and finish
- Deadbolt includes listed anti-drill, anti-pick, and reinforced strike features
- Fits common backsets and both door handing directions
- Limited lifetime mechanical and finish warranty is listed
Cons:
- Includes two keys, fewer than some keyed-alike multipacks
- Warranty terms include a seller condition in the supplied details
Verdict: The Schlage is the most compelling choice here if you prioritize clearly stated security features and a reinforced strike.
How to Choose a Black Door Knob and Deadbolt Set
Measure the Door Thickness and Backset
Before choosing a set, measure the door thickness and the backset—the distance from the door edge to the center of the knob or lock hole. Many options here fit doors 1-3/8 to 1-3/4 inches thick and adjust between 2-3/8 and 2-3/4 inches, but not every listing supplies every measurement. Also check the size of the existing bore holes and latch opening against the product specifications.
Decide Whether You Need a Knob or a Lever
Most picks in this guide use a knob, but the Kwikset Casey is a lever set. A lever may be easier to operate for some people, while a knob may better match your existing hardware or style preference. If you specifically want a knob-and-deadbolt combination, check the product type carefully before ordering.
Consider Keying and Rekeying
Keyed-alike sets let one key operate multiple compatible locks, which can reduce the number of keys you carry. This can be especially useful in a multipack. Rekeying is a separate feature: the Kwikset listing describes SmartKey rekeying, while the BESTTEN listing says its locks are not rekeyable. Choose based on whether you want shared keys as supplied or the option to change the keying later.
Match the Set to the Number of Doors
A single set may be enough for one entrance, while the BESTTEN and Brotima packages are aimed at buyers outfitting more than one door. Before selecting a multipack, confirm how many complete knob-and-deadbolt sets are included and whether the keying arrangement suits the doors you plan to use them on.
Compare Stated Security Features
Look beyond the finish when comparing exterior locks. The Schlage listing names a BHMA rating, anti-drill and anti-pick features, and a reinforced strike. Brotima states an ANSI Grade 3 standard, while other product descriptions provide fewer security details. These claims help you compare listed specifications, but they do not replace proper installation or a sound door and frame.
Check Finish, Warranty, and Installation Details
Matte black hardware can coordinate with many entry styles, but finish descriptions should be clear and consistent. The BESTTEN product details supplied here mention both satin nickel and matte black, so verify the exact option before ordering. Also compare warranty terms and installation requirements, including any notes about preinstalled screws or door orientation.
Frequently Asked Questions
Can one key operate both the knob and the deadbolt?
Several sets in this guide are described as keyed alike, meaning the included key arrangement works with the knob and deadbolt in the set. Check the exact product details, especially when buying a multipack, to confirm whether the locks are keyed alike across all included doors.
Will these sets fit any exterior door?
No. Fit depends on door thickness, backset, and the size and placement of existing holes. Many options listed here fit doors 1-3/8 to 1-3/4 inches thick and use an adjustable backset, but confirm the measurements for your chosen set and your door before buying.
What is the difference between a single-cylinder deadbolt and a knob lock?
A single-cylinder deadbolt typically uses a key on the outside and a thumbturn on the inside. The keyed knob also locks, but it is a separate lock at the handle. The two mechanisms serve different roles, so check the product details to understand how each operates from both sides.
Which option allows rekeying?
The Kwikset Casey listing describes SmartKey Security, which allows you to re-key the lock yourself. The BESTTEN listing says its locks are not rekeyable. Check the product instructions and specifications for any lock you are considering.
Which set is best for multiple doors?
The BESTTEN package includes two sets, while Brotima includes three. Compare the stated finish, keying arrangement, door-fit details, and pack contents before choosing between them.
Is a lever set the same as a knob set?
No. A lever uses a horizontal handle, while a knob is round or ball-shaped. The Kwikset Casey is a lever set; the other options in this guide are knob sets. Choose the style that suits your needs and the look of your other hardware.
Final Recommendation
For the clearest combination of stated security features, adjustable fit, and reinforced installation details, the Schlage Georgian is the strongest overall pick in this group. Choose the Amazon Basics set for a simpler single-door option, the Kwikset Casey if you prefer a lever and rekeying flexibility, or a multipack when you need to update several doors. Whichever you choose, measure your door and confirm the exact finish and keying details before ordering.
