A door knob and deadbolt combo gives you two locking points while letting you use the same key for both. The sets below pair a keyed entry knob with a separate single-cylinder deadbolt, rather than combining both mechanisms inside one piece of hardware. Before choosing, check your door thickness, backset, and latch-plate needs so the set fits your door.

Our Picks: Best Door Knob With Deadbolt Built In reviews
1. BESTTEN Keyed Alike Knob and Deadbolt Set: A Simple Satin Nickel Pick
The BESTTEN set pairs a keyed entry knob with a single-cylinder deadbolt in a satin nickel finish. Both locks use the same key, so you can unlock the knob and deadbolt without carrying separate keys. The package includes three keys.
Its adjustable latch fits a 2⅜- or 2¾-inch backset, and the set is designed for doors from 1⅜ to 1¾ inches thick. The product description specifies an all-metal construction and a KW1 keyway. It also notes that the locks cannot be rekeyed, a key consideration if you may want to match them to other locks later.
One installation detail is easy to overlook: the handle’s machine screws arrive preinstalled and need to be removed before fitting the hardware. This set is a practical choice for a standard door if you are comfortable keeping its supplied keying as-is. Compared with the Veise and Probrico options, it does not list an ANSI grade in the supplied specifications.
Pros:
- Knob and deadbolt are keyed alike.
- Adjustable latch supports two common backsets.
- Fits standard door thicknesses from 1⅜ to 1¾ inches.
- All-metal construction with a satin nickel finish.
Cons:
- Locks cannot be rekeyed.
- Only three keys are included.
Verdict: Choose the BESTTEN if you want a basic keyed-alike set in satin nickel and do not need rekeying flexibility.
2. Amazon Basics Coastal Set: Matte Black with Four Matching Keys
This Amazon Basics option combines a keyed exterior knob and deadbolt in a matte black finish. The two locks are keyed alike, and the set includes four brass keys. That extra key can be useful if several people need access, though it does not change how the locks operate.
The hardware has a stainless steel body with a steel internal structure. Its adjustable latch fits a 2⅜- to 2¾-inch backset, and the set is made for doors 1⅜ to 1¾ inches thick. The product details also specify a 2⅛-inch lock-body hole and a 1-inch latch hole, which can help you check compatibility before buying.
Installation instructions are included, and the product comes with a one-year limited warranty. The matte black look makes it a distinct alternative to the satin or brushed nickel choices here. If you want a listed ANSI grade or information about rekeying, those details are not included in the supplied specifications.
Pros:
- Four brass keys are included and keyed alike.
- Matte black finish offers a darker style option.
- Adjustable latch accommodates two common backsets.
- Includes installation instructions and a one-year limited warranty.
Cons:
- The finish may not suit doors with existing nickel hardware.
- The supplied specifications do not state an ANSI grade.
Verdict: Pick this set if you want matte black hardware, four matching keys, and a straightforward fit for a standard door.
3. Veise Keyed Alike Set: ANSI Grade 3 and DIY-Friendly Details
The Veise set pairs a keyed knob with a single-cylinder deadbolt in matte black. It is listed as ANSI Grade 3 and uses a heavy-duty stainless steel lock body. The product description also says the hardware was tested for more than 250,000 open-close cycles. Those specifications make this one of the more clearly documented options in the group, but they do not replace the need to check the fit and installation.
It comes with three matched keys and fits doors from 1⅜ to 1¾ inches thick. The latch adjusts for a 2⅜- or 2¾-inch backset, and the set is designed for left- or right-handed doors. The product description says installation requires a screwdriver and notes that the latch bolt may need its orientation adjusted. It also warns that machine screws may be preinstalled in the knob handle.
The locks cannot be rekeyed, so consider that before choosing this set for a home where you want to match existing keys. Veise lists a one-year limited warranty, a free one-year extension with registration, phone support during stated hours, and 24/7 email support. That support offering and its installation guidance distinguish it from options with fewer service details.
Pros:
- Listed as ANSI Grade 3.
- Keyed alike with three keys included.
- Fits common door thicknesses and two backsets; works with either handing.
- Includes stated warranty-extension and support options.
Cons:
- The locks cannot be rekeyed.
- Latch orientation and preinstalled screws require attention during installation.
Verdict: The Veise is a strong fit for shoppers who value a stated ANSI grade and detailed installation support, provided its non-rekeyable locks meet your needs.
4. Probrico Keyed Alike Set: Brushed Nickel with an ANSI Grade 3 Listing
Probrico’s set combines a keyed entry knob and single-cylinder deadbolt with a brushed nickel finish. The package locks are keyed alike, so one key operates both the knob and deadbolt. The product description lists ANSI Grade 3 verification and says the hardware has been tested for more than 250,000 cycles.
The steel adjustable latch fits a 2⅜- or 2¾-inch backset and doors from 1⅜ to 1¾ inches thick. The deadbolt uses a key from the outside and a thumb turn from the inside. That arrangement is common for this style of entry set, but you should still check that it matches your household’s needs and local requirements.
A notable installation limitation is that the square latch plate cannot be removed. Check the shape of your existing latch opening before ordering. Probrico also says its keyed-alike sets can use one key for up to ten sets, which may suit a home or rental property with several matching doors.
Pros:
- Listed as ANSI Grade 3.
- Knob and deadbolt use the same key.
- Adjustable latch supports two common backsets.
- Brushed nickel finish and stated multi-set keyed-alike option.
Cons:
- The square latch plate cannot be removed.
- Check the existing latch opening carefully before installation.
Verdict: Consider Probrico if you want a keyed-alike nickel set with a stated ANSI Grade 3 rating and your door can accept its fixed square latch plate.
5. Plustool Four-Pack: A Convenient Choice for Several Doors
The Plustool package includes four exterior knob-and-deadbolt sets, all described as keyed alike. That makes it the clearest multi-door option here if you are updating several entry points and want to reduce the number of keys you carry. Each set pairs a round entry knob with a single-cylinder deadbolt in satin nickel.
The product description lists a five-pin brass tumbler cylinder, a solid-column security bolt, and hardware tested for more than 250,000 cycles. It also describes stainless steel knobs and an electroplated finish. The latch adjusts for a 2⅜- or 2¾-inch backset, and the set fits doors from 1⅜ to 1¾ inches thick. The knobs are reversible for left- or right-handed doors.
Installation is described as screwdriver-only, with instructions included. However, the latch plate cannot be removed, so check your door’s existing plate arrangement before buying. The package size may also be more than you need if you are replacing hardware on just one door.
Pros:
- Four sets are included and keyed alike.
- Adjustable latch fits two common backsets.
- Reversible design works for left- or right-handed doors.
- Product details specify a brass tumbler cylinder and security bolt.
Cons:
- The latch plate cannot be removed.
- A four-set pack may be unnecessary for a single-door project.
Verdict: Choose the Plustool pack when you need matching keyed-alike hardware for several doors and have confirmed the fixed latch plate will fit.
How to Choose a Door Knob and Deadbolt Combo
Check the Door Thickness
These sets are designed for doors within a stated thickness range, but confirm your measurement before ordering. All five options list a fit for doors 1⅜ to 1¾ inches thick. If your door falls outside that range, do not assume the latch or lock body will fit without additional parts.
Measure the Backset
The backset is the distance from the edge of the door to the center of the knob hole. The products in this roundup list adjustable latches for 2⅜- and 2¾-inch backsets. Measure your existing setup and check that the selected latch can be adjusted to match it.
Look at the Latch Plate
A latch plate that does not match your door’s cutout can complicate installation. Probrico and Plustool state that their latch plates cannot be removed. If your door has a different plate shape or needs a specific installation style, inspect the existing hardware and product details before choosing either one.
Decide Whether You Need Rekeying
Keyed-alike hardware lets one key open both the knob and deadbolt. That is convenient, but it is different from rekeying, which changes a lock to work with a different key. BESTTEN and Veise explicitly state that their locks cannot be rekeyed. The supplied specifications for the other options do not provide rekeying details, so check with the seller or manufacturer if this feature matters to you.
Compare Keys and Pack Size
The BESTTEN and Veise sets include three keys, while Amazon Basics lists four. Plustool is sold as a four-set package, which is more suited to several doors than a single replacement. Probrico describes a keyed-alike option for multiple sets. Consider how many doors you are outfitting and how many people need a key.
Match the Finish to Your Existing Hardware
The available finishes include satin nickel, brushed nickel, and matte black. Finish names can look different in person and under different lighting, so use the product images as a guide rather than assuming two nickel finishes will match exactly. If you are replacing only one lock, consider how it will look beside the rest of your door hardware.
Review the Security and Support Details
Veise and Probrico list ANSI Grade 3, while the other supplied product descriptions do not state an ANSI grade. These details can help you compare the options, but a lock set is only one part of a door’s overall security. Consider the door, frame, strike area, and correct installation as well. Also review any stated warranty and support information before purchase.
Frequently Asked Questions
Is a door knob with a deadbolt built in one piece?
Not in the products covered here. Each option pairs a keyed entry knob with a separate single-cylinder deadbolt. The hardware works as a combo set, but the knob and deadbolt are installed as separate components.
What does keyed alike mean?
Keyed alike means the same key operates both the entry knob and the deadbolt in the set. Multi-set options may also use matching keys across more than one door, but check the product details to confirm how many locks are included and keyed alike.
How do I know if a set will fit my door?
Check the door thickness, backset, and the size and shape of the existing hardware openings. The products here list a door thickness of 1⅜ to 1¾ inches and latches that adjust between 2⅜- and 2¾-inch backsets. Also check whether the latch plate can be changed if your door needs a different shape.
Can I use one key for locks on several doors?
Some products describe keyed-alike options beyond one knob-and-deadbolt pair. Probrico states that a single key can operate up to ten sets, and Plustool describes its four-pack as keyed alike. Confirm the exact keying arrangement for the package you plan to buy.
Can I rekey these locks to match my existing key?
BESTTEN and Veise state that their locks cannot be rekeyed. The supplied details for the other products do not specify rekeying, so check with the seller or manufacturer before ordering if matching an existing key is important.
Are these sets suitable for a left-handed or right-handed door?
Veise and Plustool explicitly describe reversible or left- and right-hand compatibility. The supplied information for the other sets does not clearly state handing. Check the product details and installation instructions for the set you choose.
Final Recommendation
For a single standard door, the BESTTEN is a straightforward satin nickel choice if you do not need rekeying. Choose Veise or Probrico if a stated ANSI Grade 3 listing matters to you, while paying close attention to their installation details. The Amazon Basics set stands out for its matte black finish and four included keys, and Plustool is the practical pick when you need matching hardware for several doors. Whichever set you choose, verify the door measurements and latch-plate fit before ordering.
