Our Picks: Best Door Knobs For Exterior Doors reviews
1. Amazon Basics Coastal Knob and Deadbolt: A Matte Black Matched Set
This Amazon Basics option pairs a keyed entry knob with a deadbolt in a matte black Coastal style. The two locks are keyed alike, so the included four brass keys can operate both without requiring a separate key for each lock.
The listing specifies an adjustable latch for 2⅜- or 2¾-inch backsets and compatibility with doors from 1⅜ to 1¾ inches thick. Its stainless steel body and steel internal structure are paired with a zinc alloy latch bolt. A one-year limited warranty is also listed.
Compared with a standalone keyed knob, this set provides a deadbolt as well as the knob. It is a practical choice if you want both pieces in a matching finish, but check your existing door holes and measurements before ordering.
Pros:
- Knob and deadbolt are keyed alike.
- Includes four brass keys.
- Adjustable latch fits two common backsets.
- Door thickness compatibility is specified.
Cons:
- Matte black may not match existing satin nickel or brass hardware.
- Confirm the set’s fit and finish suitability for your particular exterior location before buying.
Verdict: Choose this set if you want a matte black keyed-alike knob and deadbolt with clearly stated standard-door measurements.
2. BESTTEN Keyed-Alike Set: Matte Black Hardware for a Standard Door
BESTTEN’s matte black entry set combines a keyed door knob and deadbolt. It includes three keyed-alike keys, which can simplify carrying keys when both locks are part of the same installation.
The listed fit range is 1⅜ to 1¾ inches for door thickness, with an adjustable latch for 2⅜- or 2¾-inch backsets. One detail worth noting before installation: the set is described as not rekeyable, and the machine screws come preinstalled in the handle. The instructions say to remove those screws before installing the hardware.
This option has the basic measurements needed to compare against a typical residential door. Its main trade-off is flexibility: if you expect to change the key later, the non-rekeyable cylinder may not suit your plans.
Pros:
- Includes a keyed knob and deadbolt.
- Three included keys operate the keyed-alike locks.
- Adjustable latch covers two common backsets.
- Door thickness range is clearly listed.
Cons:
- Not rekeyable, according to the product details.
- Preinstalled machine screws need to be removed before installation.
Verdict: This is a reasonable pick for a matte black knob-and-deadbolt set if the listed dimensions fit and you do not need a rekeyable cylinder.
3. Amazon Basics Coastal Satin Nickel Knob: A Standalone Keyed Entry Option
This round Coastal-style knob has a satin nickel finish and a keyed lock. Unlike the first two picks, its product details describe an entry knob rather than a knob-and-deadbolt set, so it can suit a door where you are replacing the knob alone or already have a separate deadbolt.
The knob has a brass body with a steel internal structure and weighs 1.1 pounds, according to the listing. It comes with two brass keys, a rounded steel faceplate and strike, and a zinc alloy latch bolt. The adjustable latch fits 2⅜- or 2¾-inch backsets, and the listed door thickness range is 1⅜ to 1¾ inches.
Satin nickel can be a useful match when you want a lighter, less stark finish than matte black. Keep in mind that the listing specifies the knob and its included parts, not a bundled deadbolt.
Pros:
- Brass body with a steel internal structure.
- Includes two brass keys and installation hardware.
- Adjustable latch for two common backsets.
- Door thickness range is provided.
Cons:
- Does not list a deadbolt as part of the product.
- Only two keys are included.
Verdict: Pick this satin nickel knob if you need a keyed entry knob and do not need a deadbolt included in the same package.
4. Amazon Basics Classic Matte Black Knob: A Straightforward Keyed Lock
The Classic matte black option is a keyed entry knob with a stainless steel body and steel internal structure. Its included parts are a rounded steel faceplate and strike, a zinc alloy latch bolt, and two brass keys using a KW1 keyway.
The latch adjusts between 2⅜- and 2¾-inch backsets. The listing also gives a 2⅛-inch lock-body hole and a 1-inch latch hole, which are useful measurements to compare with your existing door. Detailed installation instructions and a one-year limited warranty are listed.
Unlike the Coastal matte black set, this product is presented as a knob with a lock rather than a bundled knob and deadbolt. It may work well for a simple replacement, but make sure the door’s existing holes and hardware arrangement match the stated dimensions.
Pros:
- Matte black finish with a classic round knob style.
- Includes two brass keys and installation instructions.
- Adjustable latch fits two common backsets.
- Includes a one-year limited warranty.
Cons:
- Does not list a deadbolt as part of the package.
- Door thickness compatibility is not stated in the supplied product details, so verify it before ordering.
Verdict: Choose this knob for a basic matte black keyed replacement when its listed hole and latch measurements match your door.
5. AEEKEL Three-Pack: Keyed-Alike Sets for Multiple Doors
This AEEKEL package is designed for multiple doors. The product details describe three keyed-alike exterior lock sets, so the same key can be used across the included sets. The knobs are reversible for left- or right-hand doors, which adds flexibility when fitting different entryways.
The listing describes stainless steel construction, a copper lock cylinder, and a matte black finish. It also states that the finish is intended to resist rust and that the hardware was tested for more than 250,000 opening cycles; these are product claims rather than independent performance guarantees.
The adjustable latch is listed for 2⅜- or 2¾-inch backsets, and the stated door thickness range is 1.38 to 1.78 inches. One installation detail to check is that the square latch plate is not removable. Confirm that this plate works with your door before purchasing.
Pros:
- Three sets share the same key.
- Reversible knobs suit left- or right-hand doors.
- Adjustable latch fits two common backsets.
- Door thickness range is stated.
Cons:
- The square latch plate is not removable.
- A three-pack may be more than you need for a single-door replacement.
Verdict: Consider this pack if you need matching keyed-alike hardware for several doors and the fixed latch plate suits your installation.
How to Choose a Door Knob for an Exterior Door
Decide Whether You Need a Knob, a Deadbolt, or Both
Start by checking what is already installed on your door. A keyed entry knob controls the knob’s latch, while a deadbolt is a separate locking component. Some products here are listed as knob-and-deadbolt sets; others describe a keyed knob only. If you want both pieces to use one key, look for a set that specifically says the locks are keyed alike.
Measure the Door and Existing Holes
Before ordering, measure door thickness, the backset from the door edge to the center of the knob hole, and the diameter of the existing holes. Several picks list a 2⅜- or 2¾-inch adjustable backset and a door thickness range, but the measurements vary by product. Compare your measurements with the product details instead of assuming that every residential door is the same.
Check the Latch Plate and Door Handing
Look at the latch already on your door and note its shape and plate style. The AEEKEL latch plate is described as non-removable, so it may not suit every existing cutout. If the door’s handing matters for your setup, check whether the knob is reversible or whether the product instructions support your door orientation.
Choose a Finish That Fits Your Hardware
Matte black and satin nickel are both represented here. Think about the finish of nearby hinges, handles, and other entry hardware, as well as the look you want on the door. Product data does not establish that a particular finish is suitable for every weather exposure, so check the manufacturer’s guidance if the hardware will face direct outdoor conditions.
Consider Keys and Rekeying Needs
Check how many keys are included and whether multiple locks share a key. Keyed-alike sets can reduce the number of keys you carry, while a standalone knob may have its own key. If you may need to change the key later, pay attention to rekeying information; the BESTTEN product is specifically described as not rekeyable.
Match the Package Size to Your Project
A single keyed knob can make sense when you are replacing only one lock and already have a separate deadbolt. A knob-and-deadbolt package bundles the two components, while a multi-pack can cover several doors. Check exactly which parts are included so you do not end up missing a needed component or buying hardware you will not use.
Frequently Asked Questions
Do all of these options include a deadbolt?
No. The Amazon Basics Coastal matte black set, BESTTEN set, and AEEKEL pack are described as including a deadbolt with the knob. The two other Amazon Basics products are described as keyed entry knobs, not knob-and-deadbolt packages.
What does “keyed alike” mean?
Keyed alike means that multiple locks in a set can be operated with the same key. It can be convenient when a package includes a knob and deadbolt or when you are fitting several doors, but check the product details to confirm which locks share a key.
How do I check whether a door knob will fit?
Measure your door thickness, backset, and existing door holes, then compare those figures with the product specifications. Also check the latch plate shape and whether the package supports the door’s handing.
Are these knobs suitable for every exterior location?
The supplied details identify them for entry or exterior-door use, but they do not establish suitability for every level of direct weather exposure. Check the product’s manufacturer guidance for your specific installation location.
What is a backset?
The backset is the distance from the edge of the door to the center of the knob hole. The products with listed adjustable latches fit 2⅜- or 2¾-inch backsets. Measure yours before ordering.
Which option is best if I only need to replace the knob?
The Amazon Basics Coastal satin nickel or Classic matte black options are described as keyed knobs rather than bundled deadbolt sets. Choose between them based on finish and confirm the fit details for your door.
Final Recommendation
For a coordinated matte black knob-and-deadbolt set with clear fit details, the Amazon Basics Coastal set is a strong place to start. Choose the BESTTEN set if its non-rekeyable design works for you, the satin nickel Amazon Basics knob if you only need a keyed knob, or the AEEKEL pack if you are outfitting multiple doors. In every case, measure your door and check the latch details before ordering.
