5 Best Smart Locks for Home Security

Written by Ethan Walker

A front door can have a strong deadbolt and still leave you with one frustrating question: “Did I actually lock it?”

That uncertainty becomes even more annoying when you are already at work, travelling, lying in bed, or waiting for a family member, cleaner, dog walker, contractor or guest to arrive. A traditional lock can secure the door, but it cannot tell you whether the door is locked, create temporary access, record who entered, or let you manage the lock remotely.

That means choosing a smart lock only because it has the longest feature list can be a mistake. A lock can offer Wi-Fi, Bluetooth, fingerprints, voice control and dozens of app settings, yet still become frustrating if it does not fit your existing deadbolt, drains batteries too quickly, disconnects from your network, or makes everyday unlocking slower than using a normal key.

Home security also changes the way you should evaluate these products. Convenience matters, but a smart lock sits directly on one of the most important entry points in your home. Reliability, backup access, battery warnings, physical compatibility and control over who can enter matter just as much as flashy app features.

The best smart lock should make your front door more controlled, more convenient and easier to monitor without creating a new daily problem. That means thinking about how you unlock the door, who needs access, what happens if the battery dies, whether you want remote control, and which smart-home platform you already use.

Before choosing one, we would focus on these practical situations:

• Family home: Look for fast keypad or fingerprint access so several people can enter without carrying keys.
• Guests, cleaners or contractors: Temporary PIN codes and scheduled access can be more practical than handing out spare keys.
• Frequent travellers: Remote status checks and locking controls can reduce the anxiety of wondering whether the door was left unlocked.
• Smart-home users: Compatibility with Apple Home, Alexa, Google Home or Matter may matter more than having the largest number of unlocking methods.
• Renters or simple installations: A retrofit design can preserve the exterior lock and existing key while adding smart control inside.
• Security-first buyers: Prioritise dependable locking, access logs, backup entry methods and clear low-battery warnings over unnecessary extras.

That is why this guide does not simply rank five locks from most expensive to least expensive. Each recommendation is intended to solve a different home-security problem.

We will compare five strong options for different types of homeowners, from feature-rich fingerprint locks to simpler keypad models and locks designed around smart-home integration.

The most important differences are not always obvious from an Amazon listing. Two smart locks can both advertise app control and keyless entry while offering very different installation requirements, remote-access capabilities, backup methods and compatibility.

We will judge all five smart locks using the factors that matter most for real home security:

• Unlocking methods: Fingerprint, keypad, app, physical key, NFC or other access methods.
• Reliability: How practical the lock is for repeated everyday use by multiple household members.
• Remote control: Whether you can check, lock or unlock the door when you are away from home.
• Guest access: How easily you can create temporary, scheduled or separate codes for other people.
• Smart-home compatibility: Support for ecosystems such as Apple Home, Alexa, Google Home or Matter where relevant.
• Installation: Whether the lock replaces the entire deadbolt or works with part of your existing hardware.
• Battery management: Battery life, low-battery warnings and emergency backup options.
• Overall value: Whether you are paying for features that genuinely make your door easier and safer to manage.

For most homeowners, the best choice will be the lock that removes the biggest problem they have with their current front door. Someone who constantly forgets keys may value fingerprint access most. A family may prefer a reliable keypad. A frequent traveller may care more about remote control and activity history. A smart-home user may place compatibility above everything else.

Below, we compare the five best smart locks side by side before showing which model we recommend for overall home security, fingerprint access, smart-home integration, simple installation and other common buying priorities.

Quick Comparison: 5 Best Smart Locks for Home Security

The five locks in this guide can all replace the daily habit of reaching for a house key, but that does not make them interchangeable. The more useful comparison is what each lock adds to your front door after keyless entry is already covered.

Some buyers need several dependable ways for family members to get inside. Others care more about Apple Home Key, seeing visitors at the door, keeping the exterior hardware simple, or retaining the familiar feel of a traditional keyed deadbolt. Those priorities can change which lock represents the better purchase.

However, #1 is not automatically the right lock for your door. The Aqara U100 becomes considerably more attractive when Apple Home Key is something you expect to use every day. For an iPhone and Apple Watch household, that ecosystem advantage can matter more than ULTRALOQ's broader general-purpose appeal.

The eufy E330 solves a completely different purchasing problem. If you are planning to buy both a smart lock and a front-door camera, its integrated video design can make more sense than comparing it purely against lock-only competitors. On the other hand, buyers who already own a video doorbell may have little reason to pay for another camera at the lock.

The Yale Assure Lock 2 deserves attention for almost the opposite reason: it can be the better choice when you want less technology at the door. A household that is perfectly happy entering PIN codes may value its cleaner, more conventional keyless experience more than fingerprint readers, cameras or additional ecosystem features.

The Schlage Encode Smart WiFi Deadbolt is aimed at buyers who want connected control without completely abandoning the traditional deadbolt experience. Its combination of touchscreen entry, built-in Wi-Fi and a conventional physical key backup can be reassuring for a household that wants smart functionality without making electronic access the only way in.

The comparison also shows why buying purely from the feature count can lead to the wrong decision. A camera is valuable only if you need video at that door. Apple Home Key matters only if it fits your devices. Fingerprint entry matters only if your household will use it. The better purchase is the lock whose strongest feature removes a problem you currently experience every week.

Still Deciding? Choose the Smart Lock That Fixes Your Biggest Door Problem

At this point, the five locks can start to look more similar than they really are. Several offer keyless entry, app control and automatic locking, so comparing another column of specifications may not make the decision any easier.

Instead, think about the moment when your current front door causes the most frustration. Is it when you cannot find your keys? When somebody needs access while you are away? When you want to know who is outside? Or when you simply cannot remember whether you locked the door before leaving?

Choose ULTRALOQ U-Bolt Pro WiFi If Your Household Needs Flexibility

The ULTRALOQ U-Bolt Pro WiFi remains our default recommendation when several people use the same entrance and you do not want to dictate one unlocking method to everyone.

Its advantage is the combination. Fingerprint access can become the quick everyday method, keypad entry gives other users a straightforward alternative, and connected app control becomes useful when you are away from the property.

• Choose it if: Different family members are likely to prefer different entry methods.
• Choose it if: Fingerprint access is important, but you also want a practical keypad alternative.
• Choose it if: Remote lock management matters when you are away from home.
• Choose it if: You want door-status awareness alongside the lock itself.

Choose Aqara U100 If Your Apple Devices Should Become Your Keys

If you already wear an Apple Watch or carry an iPhone everywhere, the Aqara Smart Lock U100 gives you a reason to ignore the overall ranking and choose the product that fits your existing technology.

Apple Home Key is the deciding feature here. Instead of buying a generic smart lock and then adapting it to your Apple household, the U100 gives Apple-oriented access a central role while retaining fingerprint and PIN alternatives.

• Choose it if: Apple Home Key is a feature you expect to use regularly.
• Choose it if: You frequently wear an Apple Watch and want it involved in front-door access.
• Choose it if: You want fingerprint and keypad access for household members who will not use Home Key.
• Choose it if: You already use Aqara products and want the lock to become part of that ecosystem.

Choose eufy E330 If You Are About to Buy a Smart Lock and a Door Camera

The eufy Video Smart Lock E330 becomes much easier to justify when your shopping list currently contains two products: a smart deadbolt and a front-door camera.

The E330 adds useful video monitoring directly at the front door, but one door-mounted camera cannot cover every driveway, backyard, garage or side entrance. If you want to extend surveillance beyond the entryway, see our guide to the best wireless home security cameras to compare options for protecting other important areas around your home

Its integrated design gives you something the other four locks cannot provide in the same way: visual information about the person standing outside the entrance combined with the hardware controlling access through that entrance.

• Choose it if: You still need video monitoring at your front door.
• Choose it if: Deliveries and unexpected visitors are a major part of what you want to monitor.
• Choose it if: You prefer one integrated front-door security device over separate lock and camera hardware.
• Choose it if: Fingerprint and keypad entry are still important alongside video functionality.

  The E330 can cover access and video at the front door, but homeowners who later add dedicated eufy cameras around the driveway, garden or other entrances may also need to think about longer-term local recording. If you are expanding beyond the smart lock, our guide explains how to expand a eufy security system with HomeBase storage using SoloCam S340, HomeBase 3 and compatible SSD options.

Choose Yale Assure Lock 2 If You Want Less Technology at the Door

More features are not automatically an upgrade. The Yale Assure Lock 2 makes the strongest case when your real objective is much simpler: stop carrying keys and enter with a PIN.

That can be particularly attractive in a household where everyone understands a keypad but not everyone wants to enrol fingerprints, use a smartphone at the entrance or learn another smart-home system.

The E330 can combine smart access and video monitoring at your main entrance, but its camera is still focused primarily on the front-door area. If you already use eufy products and want to extend coverage to rooms, driveways, garages or backyards, see our guide to the best eufy PTZ cameras for HomeBase 3 to compare options designed for wider pan-and-tilt coverage around the property.

• Choose it if: PIN entry is already enough for the way your household uses the door.
• Choose it if: You prefer clean, understated exterior hardware.
• Choose it if: You value simplicity more than accumulating additional unlocking methods.
• Choose it if: You want family members to understand the lock immediately without relying on biometrics.

Choose Schlage Encode If You Still Want a Traditional Key in the Equation

Some homeowners like smart-home convenience but are not interested in making their front door feel completely digital.

The Schlage Encode Smart WiFi Deadbolt fits that buyer particularly well. Its combination of touchscreen PIN entry, built-in Wi-Fi and a conventional physical key cylinder preserves a familiar backup route while adding connected control.

• Choose it if: Keeping conventional keyed access is reassuring rather than undesirable.
• Choose it if: Built-in Wi-Fi is more important to you than fingerprint recognition.
• Choose it if: You want the experience of an established traditional lock brand moving into connected access.
• Choose it if: Your household prefers PINs and physical keys over biometric entry.

Make the Choice in 30 Seconds

Before You Order: Check the Door, Not Just the Lock

There is one purchasing mistake that no feature comparison can fix: installing a motorised deadbolt on a door where the existing bolt already struggles to move.

Close your door and operate the current deadbolt normally. If you have to push, pull or lift the door before the bolt slides into the strike, correct that alignment before expecting a smart lock motor to solve the problem.

You should also confirm the lock's dimensions, backset, door thickness and exact connectivity requirements before ordering. Product families can have multiple versions that look nearly identical while supporting different wireless protocols, hubs or smart-home platforms.

Still Cannot Decide? Start With the Most Flexible Option

If none of the specialised advantages above clearly describes you, we would return to the ULTRALOQ U-Bolt Pro WiFi.

It remains our Best Overall choice because a general household is more likely to benefit from having several practical access methods than from paying specifically for an integrated camera, Apple-focused feature or more traditional lock experience.

But the moment one specialised requirement becomes essential, follow that requirement instead of blindly following the ranking. The best smart lock is the one that fits your door, your household and the way you actually want to enter your home.

Why Waiting to Upgrade Your Front Door May Not Make Sense

A smart lock is easy to postpone because your current deadbolt probably still works. You can lock it. You can unlock it. From that perspective, replacing it can feel like something that can always wait another month.

But that is not really what you are deciding. The question is whether you want to keep living with the limitations around the lock that brought you to this guide in the first place.

If you regularly hide a spare key, wonder whether the door was locked after leaving, coordinate keys with family members, or need to give somebody access while you are away, waiting does not solve any of those problems. It simply means repeating the same routine.

Every Extra Spare Key Creates Another Thing You Have to Control

Traditional access becomes surprisingly difficult to manage once several people need keys. A copy may go to a relative. Another may be kept for emergencies. A cleaner, house sitter or other trusted person may occasionally need one.

The inconvenience is not creating the key. It is what happens afterward. You have to remember who has it, recover it when access is no longer required, and deal with the uncertainty if a copy disappears.

A smart lock with appropriate digital access options can change that model. Instead of solving every new access request by creating another physical key, you can choose a lock designed around more manageable credentials.

Small Door Problems Become Expensive in Repetition

Forgetting a key once is a minor inconvenience. Searching for keys twice every day for several years is a routine.

The same applies to checking the deadbolt before bed, turning around after leaving because you cannot remember whether you locked the door, or coordinating arrival times because someone cannot get inside.

None of those moments is dramatic by itself. Their importance comes from repetition. A feature such as fingerprint entry, PIN access, remote management or auto-lock can be valuable precisely because it addresses something that happens again and again.

• Frequently forget your keys? Fingerprint or keypad entry can remove the key from your normal arrival routine.
• Wonder whether you locked the door? A connected smart lock can provide capabilities that a conventional deadbolt cannot.
• Several people need access? Multiple digital entry methods can be easier to manage than multiplying physical keys.
• Already planning a front-door camera? An integrated option such as the eufy E330 can address two upgrades in one purchase.
• Already use Apple devices every day? A lock such as the Aqara U100 can make that existing ecosystem more useful at the entrance.

The Worst Time to Rethink Door Access Is After a Key Goes Missing

Many people reconsider their locks only after something changes: a key disappears, a former guest still has a copy, someone gets locked out, or a family member needs access unexpectedly.

At that point, the purchase is no longer being made calmly. It becomes a response to an immediate problem.

If you already know that physical-key management is becoming inconvenient, upgrading before the next access problem gives you time to choose the right system, install it properly, enrol household members and test the backup methods without pressure.

You Already Have Enough Information to Avoid Buying the Wrong Type

After comparing these five locks, you do not need to keep searching simply because there are hundreds of smart-lock listings available.

The meaningful choice is already much narrower:

Once one of those descriptions clearly matches your household, continuing to compare unrelated features can actually make the decision worse. You start giving equal weight to specifications you may never use and lose sight of the reason you wanted a smart lock.

Do Not Wait for a “Perfect” Price That May Never Arrive

Smart-lock prices can change, and retailers may offer discounts at different times. That is why we recommend checking the current price before ordering rather than treating any captured price as permanent.

But there is an important difference between checking the current deal and postponing indefinitely because the product might become slightly cheaper someday.

If the lock already fits your budget, your door and your preferred access method, the more useful question is how much value you will get from using it every day; not whether an unpredictable future promotion might save a little more.

If You Know Which Problem You Want to Fix, There Is Little Benefit in Keeping It

The decision does not need to be more complicated than that.

If you want flexible fingerprint, keypad and connected access, our first choice remains the ULTRALOQ U-Bolt Pro WiFi. If one of the specialised needs above matters more, choose the lock built around that need instead.

Either way, the value starts only after the lock is installed. Another month of comparison does not give you remote access, remove another spare key, automatically secure the deadbolt or make tomorrow's arrival home any easier.

Final Verdict: Which Smart Lock Should You Put on Your Front Door?

After comparing all five options, our recommendation comes down to one principle: your smart lock should make access easier without making your front door harder to manage.

That means we would not choose a winner simply because it has the longest feature list. The lock has to work for the people who actually enter your home every day, provide sensible alternatives when one access method is inconvenient, and add useful control when you are away from the property.

Why ULTRALOQ U-Bolt Pro WiFi Gets Our Best Overall Pick

The reason is flexibility.

A front door may be shared by adults, children, relatives and occasional trusted visitors. Those people do not necessarily have the same phone, remember the same routines or prefer the same unlocking method.

The U-Bolt Pro WiFi gives that household several practical options instead of betting everything on one technology.

• Fingerprint access for quick everyday entry.
• Keypad entry for household members who prefer a PIN.
• Connected app control for situations where you are away from the door.
• Door-sensor functionality for additional awareness around the entrance.
• Multiple access options so one preferred method does not have to serve every person in the household.

That combination gives it broader appeal than a lock whose main reason to buy depends on owning a particular phone, needing an integrated camera or preferring only keypad entry.

But Choose One of the Other Four If It Matches Your Home Better

“Best Overall” should never mean “buy this regardless of your requirements.” Each alternative in this guide has a situation where we would choose it instead.

One Last Check Before You Buy

Before ordering any smart lock, confirm that the exact model fits your door and supports the connectivity or smart-home features you expect to use.

Also check your existing deadbolt alignment. If the bolt cannot extend smoothly when the door is closed, fix the door or strike alignment first. A motorised lock should not have to force the deadbolt into position every time it operates.

Ready to Upgrade? Start With the Lock That Fits the Way You Already Live

If you have reached this point and none of the specialised alternatives solves a problem more important to you, we would stop comparing and start with the ULTRALOQ U-Bolt Pro WiFi.

It gives the average household the broadest mix of useful entry methods and connected control without requiring Apple Home Key, an integrated camera or a purely keypad-focused buying strategy to justify the purchase.

More importantly, it addresses the everyday reasons people upgrade in the first place: fewer physical-key problems, easier household access, more options at the door and greater control when you are away.

Prices and availability can change. Check the current product listing and confirm compatibility with your door and preferred smart-home setup before purchasing.

Frequently Asked Questions About Smart Locks for Home Security

Choosing a smart lock involves more than deciding whether you want a keypad or an app. Compatibility, backup access, connectivity and the way different people use the same entrance can all affect which model makes the most sense for your home.

What Is the Best Smart Lock for Home Security?

For most households, our top choice is the ULTRALOQ U-Bolt Pro WiFi. Its biggest advantage is flexibility: fingerprint entry, keypad access and connected control give household members more than one practical way to use the front door.

However, a specialised alternative can be better for a specific home. The Aqara U100 stands out for Apple Home Key, while the eufy E330 is more compelling when you also want video monitoring at the entrance.

Are Smart Locks Actually Better Than Regular Deadbolts?

A smart lock does not automatically make a door secure simply because it contains electronics. Its practical advantage is the additional control it can provide over how people enter and how access is managed.

Depending on the model, that can include PINs, fingerprints, app management, automatic locking and remote functionality. A conventional deadbolt can still be perfectly appropriate if you do not need those capabilities.

What Happens If the Battery in a Smart Lock Dies?

This depends on the model, which is why backup access should be checked before buying. Smart locks may provide alternatives such as a physical key, external emergency-power option or another manufacturer-specific recovery method.

Do Smart Locks Still Work If Wi-Fi Goes Down?

Losing Wi-Fi does not necessarily mean losing the ability to enter your house. Local methods such as a keypad, fingerprint reader or physical backup can operate differently from features that depend on internet connectivity.

What may become unavailable during an internet outage are certain remote or cloud-dependent functions. The exact behaviour varies by model and configuration, so confirm it for the specific version you plan to purchase.

Which Smart Lock Is Best for iPhone and Apple Watch Users?

From the five models in this guide, the Aqara Smart Lock U100 is our most targeted choice for an Apple-focused household because Apple Home Key is one of its defining features.

That makes it particularly interesting if you want a compatible iPhone or Apple Watch to become part of your normal entry routine rather than relying only on a PIN or fingerprint.

Which Smart Lock Has a Built-In Security Camera?

The eufy Security Video Smart Lock E330 is the camera-equipped option in our five-product lineup. It combines smart-lock functionality with front-door video monitoring in one exterior device.

We would consider it most strongly when you still need both products. If you already have a video doorbell that works well, paying for another camera inside the lock may provide less value.

What Is the Best Smart Lock If I Only Want a Keypad?

The Yale Assure Lock 2 is our preferred option in this group for buyers who value a cleaner, more straightforward keyless experience.

It makes sense when entering a PIN solves the problem you actually have. You should not pay for fingerprint recognition or an integrated camera merely because those technologies exist.

Which Smart Lock Is Best If I Still Want a Physical Key?

The Schlage Encode Smart WiFi Deadbolt is particularly attractive for buyers who want connected functionality while retaining the familiar option of conventional keyed entry.

Its combination of touchscreen access, built-in Wi-Fi and physical key backup makes it a strong fit for someone who wants a smart deadbolt without making the front door feel completely dependent on digital access.

Is Fingerprint Entry Better Than a Keypad?

Neither method is automatically better. Fingerprint access can be extremely convenient for frequent household users because there is no code to type. A keypad, however, is easier to use for people who have not enrolled a fingerprint and can be more practical for shared access.

This is one reason we like locks that provide multiple entry methods. Your preferred method can remain the fastest option without becoming the only option.

Can I Give Family Members or Visitors Access Without Giving Them a Key?

Smart locks are particularly useful when you want to reduce dependence on physical spare keys. Depending on the model and configuration, digital credentials or access codes can provide authorised users with another way to enter.

Exact code-management, scheduling and remote-sharing capabilities differ between products, so check the specific model before buying if temporary or recurring visitor access is one of your main requirements.

Can I Install a Smart Lock Myself?

Many replacement smart deadbolts are designed for installation on common residential doors, but successful installation depends on more than attaching the exterior and interior assemblies.

Your existing deadbolt should move freely when the door is closed. If you currently need to push or pull the door to turn the deadbolt, correct the alignment before installing a motorised smart lock.

What Should I Check Before Buying a Smart Lock?

Start with physical compatibility and then move to technology. Confirm your door dimensions and deadbolt configuration, then check the exact model's connectivity, backup-access method and smart-home requirements.

• Door compatibility: Check dimensions, backset and required installation space.
• Deadbolt alignment: The bolt should extend and retract smoothly with the door closed.
• Entry methods: Decide whether you actually need fingerprint, PIN, phone, key or several options.
• Connectivity: Confirm whether your desired functions use Wi-Fi, Bluetooth or additional hub hardware.
• Smart-home ecosystem: Verify the exact model supports the platform and functions you intend to use.
• Backup access: Know how you will enter if your preferred electronic method is unavailable.

Do I Need a Smart-Home Hub for a Smart Lock?

Not necessarily. Hub requirements vary considerably between products and even between different functions of the same product family.

For example, a lock may provide local keyless entry without additional hardware while certain remote controls, integrations or automations require another device. Always verify the requirements for the specific feature you want, rather than assuming every advertised capability works through the same connection.

Which of These Five Smart Locks Should I Buy?

If you do not have a specialised requirement, we would start with the ULTRALOQ U-Bolt Pro WiFi. Its combination of multiple entry methods and connected control makes it the most balanced choice in this five-lock comparison for a typical household.
