Secure Your Home With the Best Deadbolt Locks (2024)

When it comes to protecting your home, having a deadbolt lock is one of the most important steps you can take. While no deadbolt lock is fail-safe, a good one makes it much more difficult for potential burglars to enter your home.

Most deadbolts carry a grade of 1, 2, or 3, which indicates the lock’s level of security. The American National Standards Institute (ANSI) assigns these grades based on extensive tests of the lock’s ease of use, durability, resistance to lockpicking or forced entry, finish durability, and trim strength.

"Look for Grade 1 security certification on deadbolts. These generally have anti-drill metal, which makes drilling out the locking mechanism difficult—but not impossible—and anti-pick key-pin configurations," says Deane Biermeier, a licensed carpenter and contractor, as well as a member of The Spruce's Home Improvement Review Board.

Keep in mind that not every deadbolt lock is made to suit every door. You should consider things like the thickness of the door and the hardware already there. A deadbolt's effectiveness is dependent on the door's compatibility and the level of security it provides. Regardless of its grade, a deadbolt that is incompatible with your door will fail to provide the intended level of protection.

We researched dozens of deadbolt locks in a variety of styles and evaluated them based on durability, security, ease of use, and value.

  • Includes reinforced strike plate

  • Several finishes to choose from

What We Don't Like

  • No smart feature

If you're looking for the best security for your home or business, then our top choice, the Schlage B60N 619, is for you. This extremely sturdy but basic single-cylinder deadbolt lock has the highest ratings of grade 1 from theAmerican National Standards Institute (ANSI)and AAA fromBuilders Hardware Manufacturers Association (BHMA), meaning that it's certified as having passed many rigorous tests of its security, performance, and durability.

It's further reinforced for extra security, including resistance to attacks executed by kick-in, lock pick, crowbar, saw, wrench, or hammer. You caninstall the lockeasily on any door that's 1-3/8 to 1-7/8 inches in thickness, and that has a backset (the distance between the edge of the door and the center of the deadbolt) of 2-3/8 or 2-3/4 inches.

The deadbolt lock includes not only the strike plate (the metal plate with a receptacle for the bolt that affixes to the doorjamb) but also a reinforcer that fits behind the strike plate to make it even stronger. The hardware includes 3-inch screws, which are recommended to protect against kick-ins or other brute-force attacks on the door.

This lock comes with two keys. Like most single-cylinder deadbolts, it operates with a key on the outside of the door and a thumb-turn on the inside of the door. It's available in several different finishes to complement various styles of decor, including satin nickel, bright brass, aged bronze, bright chrome, matte black, and antique brass.

What We Like

  • Can re-key it yourself

  • Several finishes to choose from

  • Easy to install

What We Don't Like

  • Only rated grade 3

If you don't need the utmost protection and you're watching your budget, then the Kwikset 660 is a great option. This single-cylinder deadbolt lock is rated grade 3, which means it provides basic security against break-ins from kicks, lock-picking, or other attacks.

It installs easily into doors that are 1-3/8 to 1-3/4 inches thick, and it adjusts to fit a backset of either 2-3/8 or 2-3/4 inches. Kwikset's SmartKey Security includes the ability to easilyre-key the lockyourself; no need to call a locksmith or even remove the lock from the door. This is a useful feature not found in many budget deadbolts.

The Kwikset 660 comes with two keys and is available in several different finishes, including satin chrome, antique brass, satin nickel, and Venetian bronze. While it's not a high-security deadbolt, this lock is more than sufficient for the average home, and the ability to re-key it yourself is a definite plus. It also requires only a screwdriver for installation.

Type: Single-cylinder | Grade: 3 | Adjustable for Door Thickness: Yes | Keypad: No | Smart: No

What We Like

  • Several options for locking/unlocking the door

  • Can store up to 100 codes

  • Grade 1/AAA rating for security

What We Don't Like

  • Expensive

You can use the Schlage Encode like a regular single-cylinder deadbolt; unlock or lock it from the outside with your key and use the thumb-turn to lock or unlock it from the inside. But with a smart lock, you have other options. Work the lock by entering a code on the touchpad, which lights up so you can easily see it even in the dark—you can set up to 100 access codes for friends, pet sitters, kids, or others who need to access your home regularly—or control the lock remotely with Schlage Home app or Key by Amazon app downloaded into your phone.

You can even use voice commands if you have Amazon Alexa or Google Assistant. The lock also works with the Ring system for doorbells and door cameras. It works from your home's Wi-Fi, so there is no need for a smart hub or separate accessory.

The Encode is easy to install, with no need for wiring. It fits standard door thicknesses of 1-3/8 to 1-3/4 inches and is adjustable to fit a backset of either 2-3/8 or 2-3/4 inches. And its smart features aren't all it has going for it: It's rated ANSI grade 1 for security and AAA by BHMA, so you can have peace of mind that your home is protected.

Built-in alarm technology alerts you if the lock is tampered with. The lock comes with one key and all the hardware required for installation. You'll need to provide four AA batteries, however. The Encode is available in four different finishes and two choices of trim. While it is relatively expensive, we feel its excellent performance and many great features make it worth the price.

Type: Single-cylinder | Grade: 1/AAA | Adjustable for Door Thickness: Yes | Keypad: Yes | Smart: Yes

What We Like

  • Easy to install and use

  • Several finishes to choose from

  • Very secure

What We Don't Like

  • Only comes with one key

You won't need to fumble or search for your keys with the Schlage Keypad Deadbolt, although you have that option as well. This unconnected (it's not a smart deadbolt that can be worked remotely with an app) keyless deadbolt has a backlit keypad where you can enter your code to unlock the door.

The device comes with two 4-digit preset codes and has the capacity to store 19 unique codes at a time. You can easily create new codes at will, which makes this a great lock if you are installing the lock on a rental door, you have frequent guests, or you often have workers access your home, such as a dog walker or cleaning crew.

This commercial grade 2 lock is easy to use. To open the door from outside, just enter your code on the keypad and then turn the thumb-turn lever. To lock the door from the outside, press the "Schlage" button and then turn the thumb-turn lever. Inside, you work the lock merely by turning the thumb-turn lever, as with any standard deadlock.

The Schlage Keypad Deadbolt installs easily with no wiring necessary. It's powered by one 9-volt battery, which is included. This deadbolt lock fits any standard pre-drilled door and comes with one key. Several finishes are available, including satin nickel, aged bronze, bright brass, satin chrome, and antique pewter. A few customers have claimed that the lock doesn't always work well in very hot or very cold temperatures, though, so keep that in mind if your area experiences them often.

The 5 Best Smart Switches of 2024

What We Like

  • Easy installation over existing single-cylinder deadbolt

  • Provides numerous methods of working the deadbolt remotely

  • Can set automatic lock/unlock function

What We Don't Like

  • Requires frequent replacement of the batteries

The August Wi-Fi Smart Lock lets you easily turn your existing standard single-cylinder deadbolt into a smart deadbolt lock without the need for any separatesmart home hub, as it connects to your home's Wi-Fi. Once installed, you still have the option of using your original key to work the deadbolt, but you can also control it via the August app, by virtual assistants, including Google Assistant, Apple Homekit and Siri, and Amazon Alexa, from your phone, or through your Apple watch.

You can set it to automatically lock within a specified length of time after leaving home and to automatically unlock as you approach the door when returning home. You can also use the August app to provide virtual keys to visitors or others who need access to your home and monitor the lock's activity remotely.

This device fits over your existing deadbolt lock—it works with single-cylinder deadbolts from most common brands, including Schlage and Kwikset—so security depends on the existing deadbolt. However, you'll gain added security thanks to the August lock's ability to notify you if the door is left unlocked, if there is an attack on the door, or if someone uses the app to enter or exit your home.

The device runs on two CR123 batteries, which are included but may need to be replaced frequently. The August Smart Lock is available only in silver or black.

What We Like

  • Resists most forms of attacks on the door

  • Reasonable price

What We Don't Like

  • Lock may feel loose

If you need the security of a double-cylinder lock, we recommend this grade 2 deadbolt lock from BRINKS. Its sturdy construction resists most forms of attacks, including kick-ins, picking, bumping, sawing, and prying. The lock is easy to install and fits all doors 1-3/8 to 1-3/4-inch thick, and the 4-way adjustable latch fits any 2-3/8 or 2-3/4-inch backset.

Before purchasing, though, be sure that your city's ordinances allow double-cylinder locks in residences, as some do not. Like all double-cylinder deadbolts, this one requires a key to lock or unlock the door from both the inside and the outside.

If installing the lock at your home, you might want to consider leaving a key in the inside portion of the lock for safety should there be an emergency that requires you or your family to flee the house quickly. This reasonably priced lock comes with two keys. It is only available in a satin nickel finish.

Type: Double-cylinder | Grade: 2 | Adjustable for Door Thickness: Yes | Keypad: No | Smart: No

What We Like

  • Easy to install

  • Adds additional security

  • Available in three finishes

What We Don't Like

  • Edges of the lock may be sharp and need to be filed down

Rim locks are one of the oldest styles of door locks. Unlike a standard deadbolt lock, which installs so that the bolt protrudes from inside the door to latch in a strike plate that's positioned in the center of the door jamb, a rim lock is installed on the outer surface of the door, with a bolt that slides into a matching strike plate on the outer surface of the door jamb.

Rim locks are often used as secondary locks on front doors but can also be used as a door's main lock. This single-cylinder deadbolt is constructed of bronze alloy and is designed to prevent the lock from being picked or forced.

The lock installs fairly easily on wood or metal doors that are 1-3/8 to 2-3/8 inches thick. It comes with a flat strike and an angled strike, so you can install the one that best fits your door. All other hardware and two keys are included. The lock is available in brass, chrome, and bronze finishes.

Type: Single-cylinder | Grade: Not applicable | Adjustable for Door Thickness: Yes | Keypad: No | Smart: No

What We Like

  • Opens within one second at touch of finger

  • Can store up to 50 people's fingerprints

  • Can be control through an app

  • Available in two finishes

What We Don't Like

  • Fingerprint recognition may not work consistently, or for all people

The Eufy Security Smart Lock can be opened in four ways: use your key, tap in a code on the keypad, use the Eufy app via Bluetooth, or merely touch your finger against the lock, which recognizes your fingerprint and unlocks the door in just one second. However, the manufacturer notes that fingerprint recognition might not work well on very young children or elderly adults.

The lock stores your fingerprints in its own chip, not in the cloud, so your information is safe from hackers. Note that this lock does not work remotely via Wi-Fi or virtual assistants such as Amazon Alexa unless you also purchase the optional Wi-Fi Bridge.

This grade 2 single-cylinder deadbolt locks itself automatically should you fail to lock it yourself. It can store up to 50 people's fingerprints and up to 100 different passcodes. The Eufy security app allows you to track the lock's activity so you can see when the door was opened or closed.

It installs on most standard doors and can withstand extreme weather conditions. It requires four AA batteries, which are included. It also comes with five keys, but note that these are not easily replaced, nor is it easy to re-key this lock. The lock is available in black or nickel finishes.

Type: Single-cylinder | Grade: 2 | Adjustable for Door Thickness: Yes | Keypad: Yes | Smart: Yes

What We Like

  • Grade 1

  • Easy to re-key

  • Treated with Microban to kill surface germs

What We Don't Like

  • Handful of complaints that lock failed within a year or two

The Kwikset 980 series deadbolt is a grade 1 option that is very secure for peace of mind; it can withstand attempts at picking, bumping, kicking, and other common methods of attack. It installs easily on anystandard door, and the latch has an adjustable backset of 2-3/8 to 2-3/4 inches to fit all standard door preparations.

The deadbolt lock comes with two keys, which you can re-key yourself, if desired, without the need for a locksmith. That allows you to re-key multiple deadbolts to use the same key or to easily change the key should one be lost or stolen.

We also appreciate that the deadbolt is treated with Microban to kill germs that linger on the lock or thumb-turn, an unusual feature that could potentially reduce colds or other illnesses. Plus, unlike many other deadbolts on this list, the Kwitset 980 is available in a variety of finishes, including satin nickel, matte black, antique brass, polished chrome, and Venetian bronze.

Type: Single-cylinder | Grade: 1 | Adjustable for Door Thickness: Yes | Keypad: No | Smart: No

Final Verdict

Our favorite deadbolt lock is the Schlage B60N 619, which is a single-cylinder lock with the highest security rating of grade 1/AAA. It comes with a reinforced strike plate for even better security, and it’s available in several stylish finishes. But if budget is a concern, then the Kwikset 660, which is a grade 3 single-cylinder deadbolt that can be re-keyed easily without the need of a locksmith. It’s also available in several different finishes.

What To Look for in a Deadbolt Locks

Cylinder Type

There are two basic cylinder types: single and double.

  • Single-cylinder deadboltslike theKwikset Single-Cylinder Deadbolt (our best single-cylinder) are by far the most common type. These locks require a key to open from the outside, but they have a thumb-turned latch on the inside of the door that can be opened quickly and easily.
  • Double-cylinder deadbolts, such as theBRINKS 2718-119, require a key to open them from both the inside and outside of the door. These can be useful in situations where a door has glass panes, as the double-cylinder lock prevents a burglar from smashing a window and then reaching in to unlock the door. However, many cities prohibit the use of these locks on residential buildings due to the danger of a person being unable to escape in a fire or other emergency.

Keyed or Keyless

The traditional deadbolt lock requires a key to lock or unlock the door from the outside. However, today, many deadbolts are key-optional. There are two types of keyless deadbolts: smart deadbolts and unconnected deadbolts.

  • Smart deadboltscan be opened with a regular key but also have the option of locking or unlocking the door remotely with an app or using a touchpad or keypad on the lock’s face to gain entry to your home. Many work with various virtual assistants, such as Apple Siri, Google Assistant, or Amazon Alexa. TheSchlage Encode Smart Deadbolt(our best smart option) is one such lock, offering numerous great features to improve the lock's function.
  • Unconnected deadbolts, also called keypads or keyless deadbolts, allow you to use your regular key to work the lock but can also be locked or unlocked by entering a numerical code on the lock’s keypad. These deadbolts differ from smart deadbolts because they do not require Wi-Fi or an app to use them. We recommend theSchlage BE365 Keypad Deadbolt (our best keypad pick).

Grade

The security degree of a deadbolt lock is typically indicated by its grade, which might be 1, 2, or 3.

  • Grade 1 deadbolts are the most secure type. These locks are ideal for businesses and residences needing the highest level of protection.
  • Grade 2 deadbolts are not tested quite as rigorously as grade 1 locks and generally reflect that in their lower price. These locks are mostly for residential use.
  • Grade 3 deadbolts are mostly used as secondary locks on doors, requiring extensive security measures. They cannot withstand the kind of abuse that a grade 1 or grade 2 lock can.

Another grading system that’s becoming much more common is the one established by the Builders Hardware Manufacturers Association (BHMA). This grading system assigns letter scores of A, B, or C to deadbolts in three categories: security, durability, and finish. The best deadbolts are graded AAA in this system.Our top choice of deadbolts, the Schlage B60, is rated grade 1 by ANSI and AAA by BHMA for the highest security rating.

High-security deadbolt locks are further certified by the Underwriters Laboratories (UL) as being able to withstand more sophisticated attacks, including forcing, drilling, prying, sawing, lock-picking, and lock bumping, which involves a special key being inserted into the lock and then bumped or tapped to cause the lock’s pins to drop and unlock the door.

Material

Most deadbolt locks are made of steel, often with brass inner workings. The Prime-Line Segal SE 15361, however, is a rim deadbolt made of a solid bronze alloy. Many manufacturers offer their deadbolts with a variety of decorative finishes, including matte black, satin nickel, oil-rubbed bronze, chrome, or satin brass. Note that the lock’s strength comes from the steel it’s made of; the finish is merely a decorative touch to make the lock look nicer in your home.

“Remember that a deadbolt is only as good as the material that it locks into. You don't have much protection if your deadbolt is fastened to a flimsy door frame. Once you have a good deadbolt, use extended hardware screws to penetrate the framing lumber behind the door jamb," says Biermeier.

Strike Plate

The strike plate is the metal “box” in the door frame that accepts the bolt from the lock. The best deadbolt in the world is useless if the strike plate is weak, damaged, or improperly installed, as a weak strike plate will easily succumb to a kick from a would-be burglar.The same is true of the door frame; if your door frame is weak, then it potentially will succumb to a hard kick despite the presence of a deadbolt.

Many deadbolts are sold with a matching strike plate. These are generally heavy-duty metal, such as steel, and include long heavy screws. If you are installing a new deadbolt but not replacing your strike plate, make sure the existing strike plate is strong and without any warps, wear, or other signs of damage. For the best security, strike plates should be attached with 3-inch heavy-duty screws sunk fully into the door frame.

Re-key Ability

Some deadbolt locks, including theKwikset 660 (our best budget option), allow you to “re-key” the lock. This involves inserting the current key into the lock, followed by a special re-keying tool, and then the new, blank key. In this way, you can easily change the working key without having to actually replace the lock. Re-keying your deadbolt is a good way to increase security when moving into a new home or after losing your keys. If your home has multiple deadlocks, re-keying is a way to create one key to work all of them, thus minimizing the number of keys you need to carry.

FAQ

  • What grade deadbolt is the best?

    There are two main grading systems used for deadbolts, one issued by ANSI and one by BHMA. Under ANSI’s grading system, a grade 1 deadbolt is the best. These deadbolts are certified as passing the most rigorous tests of security and durability. Grade 2 deadbolts are not quite as secure and, thus, are less expensive. Grade 3 deadbolts are even less secure and are mostly used as a backup.

    The BHMA grading system uses letter scores of A, B, and C in three categories: security, durability, and finish. The highest score is an A, and the lowest is a C. Thus, the locks with the highest grade under this system score AAA.

  • How long should a deadbolt locks last?

    Like any mechanism with moving parts, a deadbolt does eventually wear out, thus reducing its ability to withstand brute force, lock picking, and other methods of defeating the lock. The lifespan of a deadbolt depends greatly on how often it’s used—the busier the lock, the faster it will wear out—but as a general rule, a deadbolt should last for many years and possibly decades. You’ll know it’s time to replace your deadbolt if it’s rusted or damaged, you can no longer turn it, it has excessive wiggle or the key feels loose, or you’ve lost all of the keys.

  • Can a burglar get through a deadbolt lock?

    Yes, a persistent burglar can defeat some deadbolts, particularly if the strike plate or door frame is not sturdy. A good kick may be all that’s required to break through a door in these scenarios. Doors with glass panes can be defeated by breaking a pane, reaching through the opening, and unlocking the deadbolt from the inside. Or a large doggy door might also be all that’s required for a burglar to access your deadbolt from the inside. However, most burglars are looking for a quick, silent, and easy entry and aren’t going to take the time or expend the effort required to defeat a quality deadbolt properly installed in a strong door with a sturdy frame.

  • Can a deadbolt lock be picked open?

    Again, the answer is technically yes, but in reality, few burglars are going to take the time to pick your lock. However, the best protection against such a scenario is to choose a grade 1 deadbolt, which is much harder to pick than a lower-graded option.
