A door lock and deadbolt combo gives you two locking points in one coordinated set, often with one key for both. The right choice depends on more than finish: check your door’s thickness, latch backset, and existing hole sizes before buying. These five options include keyed-alike knob sets, lever sets, and a multi-set pack, with different rekeying and installation features to weigh.

Our Picks: Best Door Lock And Deadbolt Combo reviews
1. BESTTEN Keyed-Alike Knob and Deadbolt Combo for Simple Replacements
This BESTTEN set pairs a keyed exterior knob with a single-cylinder deadbolt. Both locks use the same key, and the package includes three keys. The latch adjusts for either a 2-3/8-inch or 2-3/4-inch backset, while the listed door-thickness range is 1-3/8 to 1-3/4 inches.
The set is designed for a do-it-yourself installation and includes instructions. One installation detail to watch: the handle’s machine screws arrive preinstalled, so remove them before fitting the hardware. The lock uses a KW1 keyway, but the set is not rekeyable. If you need to match it to an existing key, that limitation matters.
Compared with the Kwikset options below, this is a simpler choice without SmartKey rekeying. It may suit a standard door replacement where the included keys are all you need. Check your door measurements first, and confirm the hole and latch layout match the set.
Pros:
- Knob and deadbolt share a key.
- Includes three keyed-alike keys.
- Adjustable latch fits two common backsets.
- Designed for DIY installation.
Cons:
- Cannot be rekeyed.
- Preinstalled handle screws must be removed before installation.
Verdict: Choose the BESTTEN if you want a basic keyed-alike knob and deadbolt set for a compatible door and do not need to rekey it later.
2. Kwikset Tylo Set with SmartKey Rekeying
The Kwikset Tylo combo combines a deadbolt with keyed entry hardware in a traditional style and satin nickel finish. Its main distinction is SmartKey Security, which lets you rekey the lock yourself using the included tool. That can be useful if you want to change the key without replacing the whole set.
The package includes adjustable latches with round and square front options or a drive-in collar, along with a SmartKey tool, two keys, screws, and an Allen wrench. The latch adjusts between 2-3/8-inch and 2-3/4-inch backsets, and the set is listed for standard doors 1-3/8 to 1-3/4 inches thick. Its security, durability, and finish are Grade 3 BHMA certified, according to the product information.
This set offers more rekeying flexibility than the BESTTEN and Amazon Basics options. The trade-off is that you should be comfortable following the SmartKey instructions if you plan to change the key. The product information also describes the entry hardware as both a lever and a knob in different places, so check the current listing and package details if that distinction is important to you.
Pros:
- SmartKey lets you rekey the lock yourself.
- Includes multiple latch-front options.
- Adjustable for two common backsets.
- Grade 3 BHMA certified for security, durability, and finish.
Cons:
- Entry-hardware style is described inconsistently in the supplied product details.
- SmartKey rekeying requires following the included process and using its tool.
Verdict: The Tylo is a strong fit if you want a traditional combo set with rekeying flexibility and a range of latch options.
3. Plustool Four-Pack for Several Exterior Doors
The Plustool listing is for a four-pack of satin nickel knob and deadbolt combos. The sets are described as keyed alike, a practical arrangement if you are outfitting several doors and want to use the same key across them. Each combo uses an exterior keyed knob and a single-cylinder deadbolt with a key on the outside and a thumb turn on the inside.
The set is listed for doors 1-3/8 to 1-3/4 inches thick, with an adjustable latch for 2-3/8-inch or 2-3/4-inch backsets. The product details describe a five-pin brass tumbler cylinder, a solid-column deadbolt, and a stainless steel knob with a satin nickel finish. The latches are reversible for left- or right-handed doors, but the latch plate is not removable.
This pack is a different kind of value proposition from the single-set options: it is intended for multiple doors, not just one entry. Its keyed-alike convenience is useful for a household or a property with several compatible doors. Before ordering, verify that the fixed latch plate works with your door preparation, since it cannot be removed.
Pros:
- Four combo sets are included in the pack.
- Sets are described as keyed alike.
- Adjustable latch fits two common backsets.
- Reversible for left- or right-handed doors.
Cons:
- Latch plate is not removable.
- A four-pack may be more hardware than you need for a single door.
Verdict: Consider the Plustool pack when you need matching knob-and-deadbolt hardware for several compatible doors and want one key to operate the sets.
4. Amazon Basics Coastal Set in Matte Black
This Amazon Basics combo pairs a keyed entry knob with a deadbolt in a Coastal style and matte black finish. The knob and deadbolt are keyed alike, and the set comes with four brass keys. Its adjustable latch covers 2-3/8-inch and 2-3/4-inch backsets, with a listed fit for doors 1-3/8 to 1-3/4 inches thick.
The product information lists a stainless steel body, steel internal structure, a rounded steel faceplate and strike, and a zinc alloy latch bolt. It also includes installation instructions and a one-year limited warranty. These details make it a straightforward option for someone who wants a coordinated dark finish and a familiar keyed-alike setup.
Unlike the Kwikset picks, this set is not described as having SmartKey rekeying. Its listed keyway is KW1, so check whether that suits your plans before purchase. The product information also specifies the assembly-hole sizes, which can help you compare it with an existing door preparation.
Pros:
- Knob and deadbolt use the same key.
- Includes four brass keys.
- Adjustable latch covers two common backsets.
- Matte black finish and a one-year limited warranty.
Cons:
- Rekeying is not listed as a feature.
- The dark finish may not suit every door or hardware scheme.
Verdict: Pick the Amazon Basics set if you want a matte black keyed-alike combo with a clear fit range and do not need a listed rekeying feature.
5. Kwikset Tustin Lever and Deadbolt Set
The Tustin combines a keyed entry lever with a single-cylinder deadbolt in satin nickel. It is a useful alternative to a round knob if you prefer a lever-style handle. The lever is fully reversible for left- or right-handed doors, which adds flexibility when matching the set to your entry.
Like the Tylo, this Kwikset set includes SmartKey Security, allowing you to rekey the lock yourself. The product details also state that the mechanical hardware comes with a lifetime mechanical and finish warranty. Microban product protection is listed for the hardware; this feature does not replace normal cleaning or care.
The supplied details advise measuring your door’s backset, cross bore, and thickness before buying, but do not list specific fit dimensions for the Tustin set. That makes checking the product listing and your existing door preparation especially important. Compared with the Tylo, the Tustin is the clearer choice if you specifically want a lever rather than a knob-style entry handle.
Pros:
- SmartKey allows you to rekey the lock yourself.
- Reversible lever suits left- or right-handed doors.
- Includes a single-cylinder deadbolt.
- Listed with a lifetime mechanical and finish warranty.
Cons:
- Specific door-fit dimensions are not included in the supplied details.
- You should confirm the backset, cross bore, and door thickness before ordering.
Verdict: The Tustin is a good option if you prefer a reversible lever and want SmartKey rekeying, provided your door measurements match the listing.
How to Choose a Door Lock and Deadbolt Combo
Match the lock to your door measurements
Start with the door thickness and latch backset. Several picks here fit doors from 1-3/8 to 1-3/4 inches thick and adjust to a 2-3/8-inch or 2-3/4-inch backset, but do not assume every set has the same fit range. Measure your current door and compare it with the exact product specifications. Also check the cross bore and other hole sizes when they are provided.
Choose a knob or lever
A knob and a lever work differently in the hand and give the door a different look. Pick the style that suits how you use the entry and coordinates with your existing hardware. If your door has a specific handing, look for a reversible design or confirm that the product supports the correct orientation.
Decide whether you need keyed-alike locks
Keyed-alike hardware lets one key operate both the entry lock and deadbolt. That can reduce the number of keys you carry. If you are buying sets for several doors, check whether the listing says the sets are keyed alike across the pack—not only within each individual combo.
Consider rekeying needs
SmartKey rekeying is listed for both Kwikset options in this guide. The BESTTEN set is specifically described as not rekeyable, and rekeying is not listed for the Amazon Basics or Plustool sets. If you need to change the key later, make that feature a priority and follow the manufacturer’s instructions.
Check what comes in the box
Package contents can affect installation. Look for the number of keys, latch options, strike hardware, tools, and instructions. The Tylo, for example, lists multiple latch-front options and a SmartKey tool. The Plustool set has a fixed, non-removable latch plate, which may not suit every door preparation.
Compare finish, warranty, and certifications
Finish is a visible choice, but it is not the same as a security specification. Consider how satin nickel or matte black will look with your other hardware, then check the product’s stated certifications and warranty separately. The Tylo lists Grade 3 BHMA certification and a lifetime mechanical and finish warranty; Amazon Basics lists a one-year limited warranty.
Frequently Asked Questions
What is a door lock and deadbolt combo?
It is a set that pairs an entry lock, such as a knob or lever, with a separate deadbolt. The combinations in this guide use a key from the outside and a thumb turn on the inside for the single-cylinder deadbolt.
Can the knob or lever and deadbolt use the same key?
Yes. Several sets here are described as keyed alike, meaning the entry lock and deadbolt can use the same key. Check the listing carefully if you also want multiple sets to share one key.
What measurements should I take before ordering?
Measure your door thickness and latch backset first. Also check the cross bore, latch arrangement, and existing holes where possible. Compare each measurement with the product’s fit details rather than relying on the appearance of your old hardware.
What does SmartKey rekeying do?
SmartKey lets you rekey compatible Kwikset locks yourself using the included process and tool. The Tylo and Tustin sets list this feature. Follow the product instructions, and confirm the lock is compatible before attempting to rekey it.
Is a knob or lever better for an exterior door?
Neither style is automatically right for every home. A knob gives you a round handle, while a lever offers a different grip and appearance. Choose based on your preference, door layout, and the set’s fit and handing requirements.
Does a keyed-alike combo mean all my doors use one key?
Not always. Keyed alike may refer only to the knob and deadbolt in one set. For several doors, look for wording that specifically says the separate sets in the package use the same key, as the Plustool listing does.
Which option is best if I need to rekey later?
The Kwikset Tylo and Tustin list SmartKey rekeying. The Tylo also lists its door-fit range and multiple latch options, while the Tustin is a lever set and advises checking your door measurements. Choose between them based on your handle preference and fit.
Final Recommendation
For a standard keyed-alike knob set with a clear fit range, the BESTTEN is a straightforward pick, as long as you do not need to rekey it. Choose the Kwikset Tylo for SmartKey rekeying and listed latch options, or the Tustin if you prefer a lever. For several doors, consider the Plustool four-pack; for a matte black single set, the Amazon Basics option is worth comparing. In every case, verify your door measurements and installation requirements before ordering.
