The Best Biometric Door Locks for Office, Home and Apartment

Fact checked by Teddy B.Miller

best biometric door lock

Keeping a home safe and burglar-free is the number one priority of a homeowner. You don’t ever quite know when a person sees yours as a target. As a result, it’s essential to have adequate protection against these would-be burglars.

The best biometric door lock could offer this protection without question. Its complex activation and design will guarantee most thieves have no shot at bypassing it. But sadly, finding high-quality biometric door locks isn’t always the easiest process.

Various factors will need consideration before choosing an acceptable option. It can be overwhelming to a person who’s never looked into these devices. But here’s a quick little overview of what I’m talking about to provide an idea:

  • Door Type: Are you looking for a front door, back door, or bedroom door lock? Some biometric locks won’t work on particular doors, so this factor becomes vital. If you don’t consider it, choosing a lock that’s unusable becomes a lot more probable.
  • Construction Strength: You’ll want a biometric lock made from high-quality, solid construction materials. Otherwise, there isn’t much point in getting one as a swift kick might break right through it.
  • Unlocking Mechanisms: Top-tier options will come with multiple ways of unlocking the lock, such as voice activation, fingerprints, or even a physical key. Each buyer will need to decide what unlocking mechanism suits their situation the best.

It might seem a little confusing now, but it’s about to get a lot simpler. We’ve compiled a list of the 12 most biometric door locks to offer an idea of what’s available. We chose each one based on having certain desired features that separate them from the pack. You’ll learn more about these features later on in our buying guide.

Best Biometric Door Lock Reviews

1. ULTRALOQ U-Bolt Pro Biometric Door Lock

The ULTRALOQ ‎U-Bolt Pro Biometric Fingerprint Door Lock is a solid way to start our list as it comes with several crucial, appealing features. These features allow this fingerprint door lock system to offer suitable protection for my house.

One of my favorite things about it is the Bluetooth and smartphone compatibility. I could access and see a log of who came into my home through an easy-to-use app. So I was always aware of who was inside my house and at what time.

I was also pleased with this product’s 360-degree live fingerprint reader. It made unlocking my front door a simple one-touch process, which didn’t require any effort. No longer do I have to rely on keys or other unlocking mechanisms to get into my house.

Moreover, it can store up to an impressive 120 fingerprints and has 60 available PINs. It made customizing my locking experience much more manageable. Plus, it offers a significant amount of protection that any thief would have trouble cracking.

Installing this fingerprint front door lock wasn’t too difficult, either. It was a DIY installation that only required a screwdriver to replace the deadbolt on my front door. I don’t see how most people would have any issues with it.

But I did find the default auto-lock feature a little too quick for my needs. For example, it only provides me with 30 seconds before it locks the door automatically. Thankfully, I found a setting that allowed me to change the duration.
  • Bluetooth compatibility
  • Operated through a smartphone app
  • Simple to use, 360-degree fingerprint reader
  • Stores 120 fingerprints and 60 PINs
  • Easy DIY installation
  • Quick auto-lock feature
Overall, I was rather pleased with this door lock’s performance. Its auto-lock feature was the only gripe that provided me with some frustration. Otherwise, the ULTRALOQ U-Bolt Pro finger scanner lock met my expectations.

2. Ardwolf A60 Biometric Door Lock System

Ardwolf’s A60 Biometric Door Lock System is one of our list’s more durable fingerprint door locks. It earns this distinction with its robust and durable stainless steel construction that offers a few benefits.

The product didn’t feel flimsy and contained well-crafted controls on its interface. I didn’t find any reason to believe it won’t last several years as a door lock. Plus, it has proven anti-rust and anti-drilling properties to ensure its longevity.

I also found myself intrigued by this product’s 360-degree fingerprint recognition. It offered a quick reading of my finger and worked without issues. Some other fingerprint door or smart locks tend to be frustrating if a user doesn’t position their finger perfectly.

This lock’s overall protection level was another impressive attribute. It has an anti-peep password that prevents the device’s interface digits from getting worn. As a result, a person can’t guess my code by looking at the worn-out numbers.

I was pleased with its versatility, as well. This keyless smart lock was built to work on indoor and exterior doors without issue. I didn’t see why it couldn’t based on my experiences and other people’s customer reviews.

The 8-digit keypad did give me some pause as it limited the number of combinations. After all, most options come with a 10-digit keypad and provide more possibilities. It’s a minor issue, but one worth thinking about before spending money on it.
  • Durable, stainless steel construction
  • Anti-rust and anti-drilling properties
  • Quick, effective 360-degree recognition
  • Anti-peep password
  • Suitable for indoor and exterior doors
  • 8-digit keypad
The 8-digit was annoying when first using the device, but I got used to it. I had more than enough combination possibilities to make an effective PIN. In other words, it still made me feel a lot safer than my previous deadbolt.

3. Samsung SHS-P718-LMK Biometric Door Lock

Our next option. Samsung’s SHS-P718-LMK Digital Biometric Door Lock, is different from the other smart locks on our list. This Samsung biometric door lock doesn’t rely on a turning handle but rather a push/pull concept.

As someone who prefers push/pull doors, this aspect was a winning one for me. It made entering into my home a lot more convenient and required less effort. The ease was only increased with its user-friendly interface and controls.

I didn’t feel uncomfortable or overwhelmed when using the interface. I’m not the most electronic savvy person, and Samsung ensured even I couldn’t mess it up. Anyone who buys this smart lock shouldn’t have any issue operating it correctly.

The automatic wake-up feature was appealing, as well. It made the door wake up the moment it detected my presence with its equipped IR sensor. Due to this, it removes the need for any start-up button and creates a more convenient using experience.

If I wanted to be extra cautious, this finger scanner door lock has a double authentication mode. It requires an access code and fingerprint scan to unlock the door. As a result, it could be an essential feature for anyone in a high-crime area.

However, I was a little thrown back by its higher price tag. It’s among the higher-priced options on our list and a little bit outside what I feel comfortable paying.
  • Push/pull opening concept
  • User-friendly interface and controls
  • Simple using process
  • Convenient automatic wake-up feature
  • Double authentication mode for extra security
  • A higher-priced option
In the end, I found this finger scanning door lock worth its costly price tag. Its long list of features made the decision a little easier to swallow. But I could see how other customers would feel differently.

4. ULTRALOQ UL3 BT Biometric Keyless Door Lock

Fingerprint locks can be frustrating when they’re built without multiple practical unlocking methods. But ULTRALOQ’s UL3 BT 5-in-1 Biometric Keyless Door Lock doesn’t fall into this category as it offers five ways of getting into my home.

I can open my door using my fingerprint, PIN code, smartphone app, knock-to-open feature, or a key. The lock ensures that I always have a method of getting into my home. Its knock-to-open feature is particularly impressive.

For instance, I don’t even have to open the app to unlock my door. It’s just a simple matter of knocking on my phone four times, and the door opens. It’s truly a convenient and helpful feature that makes my life a lot easier.

I was intrigued by its versatility, too, with its reversible handle. It allows the lock to work on either right-handed or left-handed doors without any issue. Plus, it’s made from weatherproof material to work on inside or outside doors.

ULTRALOQ was kind enough to offer an 18-month warranty, as well. I tend to break things at a much higher rate than most normal humans. Due to this, warranties are a must for any electronic device or item that I purchase.

I was a little disappointed to see some customers had issues with the packaging. It seems the product arrived with missing screws on a few occasions. Thankfully, I didn’t experience these issues when my particular lock arrived.
  • Five access methods (fingerprint, PIN code, app, knock-to-open, and backup key)
  • Ultra-convenient opening with knock-to-open feature
  • Reversible handle for left or right-handed applications
  • Usable on inside or outside doors
  • 18-month warranty
  • Some packaging issues
Aside from the occasion packaging issue, I didn’t see or experience anything that made me second guess this lock. It worked well and should remain a usable smart lock for as long as I require it.

5. Sifely Biometric Door Smart Lock

Sifely’s Biometric Door Smart Lock has a solid reputation among rental property owners and Airbnb users for its practicality. It’s not hard to see why, as this smart lock offers several appealing features and quality performance.

For instance, I found myself liking its easy installation process. This biometric door lock residential device didn’t require much or thought to install. The entire activity only needed a screwdriver and following their helpful instruction video.

The product’s WI-FI compatibility was another appealing highlight. It allowed me to lock or lock my door from anywhere and at any time. Plus, I could remotely set up codes and check logs about what’s going on inside my house.

I also liked the satin nickel finish that provided this lock with some style. Most biometric door locks for business or fingerprint door lock residential devices tend to be ugly. But this one meshes well with my door’s style and isn’t an eyesore.

More importantly, this product’s another one with an effective fingerprint activation. I didn’t need to use any of the other unlocking methods because this one worked well. After all, it almost always recognized my fingerprint on the first attempt. What’s more, it has passage mode for seamless entry and exiting during the schedule of your choice.

I was a little confused on why I have to remove the door handle when using the emergency key. It’s rather impractical, mainly when a power supply issue does occur. A few other customers noted similar feelings about this feature in their reviews.
  • Easy installation process
  • Helpful instruction video
  • Wi-FI compatibility for remote access
  • Stylish, satin nickel finish
  • Effective fingerprint activation
  • Must remove handle to use the backup key
The emergency key issue is a tad annoying, but I can’t complain about the lock’s overall performance. It does what’s required to keep my home protected. I just need to keep tabs on the battery life, so I don’t require my emergency key.

6. HuTools ‎KS02 ORB Fingerprint Door Lock

One of the more affordable options would be HuTools’s ‎KS02 ORB Fingerprint Door Lock. But its low price tag doesn’t stop it from being an effective unit. I still found several aspects of it rather interesting.

A solid example is its ability to function as a fingerprint bedroom door lock. It offers 20 sets of fingerprints, which allowed me to grant access to everyone I needed. In addition, it’ll only require placing my finger on the fingerprint for a split second, and the door opens.

The passcode activation was a breeze, as well. It comes with an easy-to-use 10-digit keypad that’s comfortable to utilize. Users can even choose the length of their code (between 4 to 10 digits) based on their needs. I went with a smaller one as my memory isn’t the best.

I wouldn’t recommend overlooking its emergency power supply capability, either. It’s a feature that allows me to connect the lock to an external power bank when there’s a power outage. Moreover, the lock has a low-battery indicator to alert me when the batteries are getting low.

I was a fan of HuTools offering two style choices, traditional or contemporary. I ended up choosing traditional as it meshed better with my particular door style. But the modern option looks decent and should blend into the right situation.

But I’m not going to lie and say I didn’t miss the built-in app of other locks. It would’ve made this option even more convenient, as accessing fingerprint security locks remotely is always a nice touch.
  • Among the more affordable options
  • Stores 20 sets of fingerprints
  • Quick fingerprint activation
  • Easy-to-use, 10-digit keypad
  • Emergency power supply capability
  • Two style choices (traditional or contemporary)
  • No built-in app
All in all, the lack of a built-in app was a slight bummer. But it’s something that I can learn to deal with, especially at this affordable price.

7. HARFO ‎HL99 Fingerprint Door Lock

The HARFO ‎HL99 Biometric Fingerprint Door Lock offers additional security with its private lock feature that acts as a fingerprint deadbolt lock. It’s an appealing aspect as I can use it to provide myself with privacy even to those with a code or acceptable fingerprint.

I was also pleased with this product’s 4-in-1 access method. It allows users to unlock their doors using an access card, fingerprints, access codes, or a metal mechanical key. Each one worked effectively when I was trying them out.

More importantly, the included 3-D fingerprint scanner was noticeably impressive. Each unlocking was quick and rarely required multiple attempts. It certainly beats having to carry a heavy mechanical key like I was previously.

The automatic locking feature was another aspect to catch my attention. It ensures the smart device locks automatically after each fingerprint access. Therefore, I always felt safe and didn’t ever wonder about my door being closed outside my home.

Moreover, the OLED display and voice guide made setting up each program relatively simple. I didn’t end up having a single issue setting up this lock in my preferred ways.

It was a little surprising to see a few buyers mention customer service issues, though. These customers seemed to have a problem reaching HAFLO with their questions. It’s not a great look for a company with such a stellar reputation.
  • Private lock feature offers additional security
  • 4-in-1 access methods (access card, fingerprints, access codes, and key)
  • Quick, reliable 3-D fingerprint scanner
  • Automatic locking feature
  • Easy setup with OLED display and voice guide
  • Customer service issues
Honestly, I wouldn’t worry too much about the customer service issues. These reports were infrequent, and most people seemed overly happy with this smart lock. Plus, this lock’s performance was more than acceptable for my needs.

8. Megafeis FB50 Fingerprint Smart Padlock

This next option, Megafeis’s FB50 Fingerprint Smart Padlock, is a solid option for smaller security jobs. Its stainless steel padlock construction will offer sufficient tamper resistance when locking up fences, exterior doors, and cabinets.

I installed it onto my shed’s door and found it more than adequate for the job. In fact, I even had a friend try to break through, and he didn’t have any luck. I have no reason to believe its stainless steel padlock won’t keep my valuables safe and where they belong.

As for its unlocking process, the lock utilizes fingerprint scanning. It works like any other lock on this list by putting my finger up to the scanner and waiting a split second. Likewise, it hasn’t caused me many problems with misreads.

The lock comes with a user-friendly USB rechargeable lithium battery, as well. I haven’t had to recharge it yet, as this lock has a 2-month lifespan on a single charge. But I did test it out with a micro USB cable charger and didn’t experience any issues.

Its compact padlock design lets me carry it anywhere, too, which is a nice touch. It makes using the device in multiple locations a lot easier than with other options on this list. Furthermore, this lock is the least costly option among our choices.

As with a few other customers, I had some issues using the product’s built-in app. It was challenging to register my fingerprints and the lock without becoming rather frustrated. Luckily, there’s no need to use it after this initial process.
  • Durable, stainless steel construction with tamper-resistance
  • Effective fingerprint scanning
  • User-friendly USB rechargeable lithium battery
  • Compact, padlock design
  • Least expensive option
  • Subpar built-in app
Once I got through the initial setup with the mobile app, I was pleased with the padlock’s performance. The initial hassle ended up being worth it. But I could imagine some buyers feeling otherwise.

9. Smonet ‎De-door-16h-1164 Biometric Door Lock

Another solid front door or office space lock would be Smonet’s ‎De-door-16h-1164 Biometric Deadbolt Door Lock. It’s known for keeping things convenient and hassle-free with its usability after installation.

One primary attribute behind this high convenience level is its touchscreen design. It made punching my passcode into the lock much smoother than with other models. Using the fingerprint scanner wasn’t uncomfortable, either.

I was also pleased with its zinc alloy body that offers durability and a modern style. As a result, it brings some flair into my home’s decor without sacrificing any performance quality. It’s a nice combination to have in a smart door lock.

The lock’s battery lifespan is an impressive six months or 5,000 openings. As someone who despises changing batteries, I was rather thrilled by this feature. Changing the batteries also isn’t tricky as this product runs on four AA batteries.

Its 5-in-1 design (fingerprint, passcode, IC card, Bluetooth, and key) will ensure everyone can find a suitable way to unlock the device, as well. I should also note that this model comes with a 1-year warranty. These policies are always a nice thing to have in a person’s back pocket.

But I did find the included instructions to be a little subpar. Thankfully, I have experience installing these products and got the job done without needing them. A newbie might not be as lucky and could need to consult a professional.
  • Convenient touchscreen design
  • Modern, durable zinc alloy body
  • 6-month battery lifespan
  • 5-in-1 design (fingerprint, passcode, IC card, Bluetooth, and key)
  • Offers 1-year warranty
  • Poor installation directions
The installation instructions being unhelpful were an unexpected issue. But I don’t have any other reason to be overly concerned about this device. I could certainly do a whole lot worse among high-tech security devices.

10. HuTools Fingerprint Deadbolt Door Lock

Some fingerprint door locks are overly complicated for no reason. HuTools’s Fingerprint Deadbolt Door Lock does the opposite and keeps things simple. It’s a refreshing change of pace within this often over-complicated marketplace.

For instance, this lock having two unlocking methods was an appealing trait. It only allows you to unlock the door using a fingerprint or passcode. But what makes this a positive aspect is both are effective and don’t cause any hassles.

The anti-peeping keypad was another attention-grabbing attribute. I can input random numbers before and after my correct code to throw off thieves. It’ll still unlock the door as long as the proper sequence of numbers is within the random mess.

Moreover, installing this device wasn’t overly time-consuming or difficult. It only required following the included instructions and a handy screwdriver. The entire process took a few minutes tops and shouldn’t even be difficult for inexperienced users.

It was a little shocking this option has an affordable price tag, as well. I fitted this device into my budget with ease and still had some cash left over for other home improvement products.

My only complaint about this smart lock would be its battery life. It runs on four double AA batteries and uses them up quickly within a week and a half. But I managed to solve this issue by using rechargeable batteries.
  • Simple design for easy use
  • Two issue-free, effective unlocking methods (fingerprint or passcode)
  • Anti-peeping keyboard confirming correct codes
  • Easy installation with included instructions and a handy screwdriver
  • An affordable option
  • Short battery life
The battery usage issue does put a slight damper on its overall performance. But it’s a minor issue that I easily solved by utilizing rechargeable options. From there, I didn’t have any complaints about this affordable HuTools door smart lock.

11. SCYAN X7SSN Fingerprint Keypad Door Lock

SCYAN’s X7SSN Fingerprint Keypad Door Lock is one of the more user-friendly options available for homeowners. It earns this distinction with its semiconductor fingerprint sensor that provides solid performance flexibility.

In other words, this feature is adaptable to various conditions. It didn’t matter whether my fingers were sweating or overly dry: this finger scanner functioned correctly. Most fingerprint scanners mess up from time to time, but I haven’t had a single issue yet.

This lock will also function well as a fingerprint door lock for office usage. It will perform satisfactorily in this role because the device can store 100 fingerprints and 100 user codes. Therefore, it can support a large number of people inside an office environment.

I found myself liking the product’s outside double layer lock panel, as well. It’s a heavy-duty construction that should provide significant resistance against would-be thieves. I even tried tampering with it a bit to see if I could bypass it and failed miserably.

The lock’s low-battery indicator isn’t something to overlook, either. I’ll never be surprised by it running out of power and can address the situation quickly.

As for its flaws, I was surprised by the loudness of its unlocking mechanism. I would certainly hear it from another room in my home if I used it on an interior door. Therefore, it might not be a suitable choice as a bedroom door lock in some situations.
  • User-friendly design
  • Adaptable semiconductor fingerprint scanner
  • Stores 100 fingerprints and 100 user codes
  • Heavy-duty double layer lock panel
  • Equipped with a low battery indicator
  • Loud unlocking mechanism
The loud unlocking mechanism shouldn’t take away from its other appealing features. I had no problems with its loudness when using it as a front door lock. In this capacity, it met my expectations and didn’t cause a raucous.

12. CIVIGEM Biometric Keyless Entry Door Lock

Our final option, CIVIGEM Biometric Keyless Entry Door Lock, ends this list with an impressive bang. It has more than a few eye-catching attributes that could help improve any home’s security.

An excellent example would be its well-crafted zinc alloy lock panel. I noticed this aspect didn’t feel flimsy at all and should provide quality long-term usage. Plus, it doesn’t hurt that the construction looks nice and modern.

I was also thrilled to see this model came with six unlocking methods: finger scanning, passcodes, Bluetooth mobile app, RFID, voice control, or a mechanical key. So it provides a bit more flexibility than I’ve experienced with other keyless entry door locks.

This product shouldn’t have any issues working in various situations, as well. It’s versatile enough to work in offices, homes, rental properties, hospitals, and hotels. After all, the customer reviews are filled with people expressing its ability to work in diverse locations.

I was intrigued by its ability to provide temporary access codes, too. The product’s Wi-Fi compatibility allows me to create schedule passcodes to share with visitors remotely. I’d imagine this being a beneficial trait for Airbnb users or renters.

The lack of a lock button on its keypad was a tad annoying, though. I had to rely on its auto-locking feature or use its mobile app to lock effectively. It’s not a massive deal, but it could be a convenience issue for some buyers.
  • Well-crafted zinc alloy lock plate
  • Modern construction
  • Six unlocking methods (fingerprints, passcodes, app, voice control, key, RFID)
  • Suitable for various applications (homes, hotels, hospitals, etc.)
  • Provides temporary access codes
  • No lock button on the keypad
In the end, I didn’t have any issues getting used to the lack of a keypad lock button. Its performance in other areas more than made up for this slight inconvenience. The lock is a solid addition to my home security and does its job without being a hassle.

What to Look for When Buying Biometric Door Locks


Biometric or finger scan door locks won’t all be the same quality. However, certain factors will determine what options best suit your needs as a homeowner. This section will dive into these factors to make your shopping experience much smoother.

Door Type

The location of your intended door lock is crucial. You’ll need to think about what kind of door your new lock is being installed onto before buying one. Otherwise, it could be a waste of money and time.

For instance, most biometric or smart locks won’t have any issues installing on front or back doors. It’s just a simple matter of choosing between a right-handed and left-handed set. Once you make this choice, you’ll have a solid biometric front door lock.

But things get a little trickier when installing them on bedroom or office doors. Some biometric locks are labeled for interiors only, meaning you can only utilize them on interior doors. In other words, a lock that works on a front or back door might be a problematic fit for an office or bedroom door.

I should also note that sliding doors aren’t compatible with sliding doors. In fact, there aren’t any high-quality biometric locks capable of working well with these door types.

Construction Strength

There’s no point in buying a biometric lock with a flimsy construction. You’ll instead want one made from high-quality materials like zinc alloy, which can withstand blunt force. It shouldn’t break or give easily and stop would-be thieves from getting into your home.

I’d suggest looking at another customer’s fingerprint door lock review or biometric door lock review to get a better handle on each option’s strength: more than one couldn’t hurt. These resources will provide enough information to determine its performance quality. After all, nothing gets a potential customer angrier than a useless biometric fingerprint lock.


The cost will also play a role in any buying experience. Choosing a biometric lock isn’t any different, as these devices vary drastically when it comes to price. Each buyer will need to create a budget based on what they deem essential within these devices.

For instance, a person looking for an option with a built-in intruder alarm will need higher budgetary ranges. Accounting for these details is the only way to ensure your budget remains realistic and valuable.

Battery Life

The best fingerprint door lock or smart door lock will come with extended, long battery life. It’s a key feature to prevent users from constantly changing the batteries. In most cases, these locks will be powered by AA batteries, which does make them rather convenient.

I’d also recommend buying options with an additional power source. It’s a simple method of preventing anyone from getting locked out during power outages.

Unlocking Mechanisms

If you intend on having multiple people coming in/out of your home, investing in a biometric door lock with multiple unlocking mechanisms is an intelligent move. They’re a useful preventative measure to ensure whoever’s going into your home is invited.

Most biometric or smart locks do offer these various unlocking mechanisms. You’ll see them contain several options like RFID entry tags, passcodes, and fingerprint scanners. It never hurts to add as much protection as possible to your home’s doors.

In fact, Airbnb users tend to prefer biometric locks with various unlocking mechanisms.


Every purchase isn’t always a winner. Sometimes, you buy the wrong item or arrive broken to the point where it’s unusable. Unfortunately, these situations become even more frequent when purchasing electronic devices, such as biometric fingerprint door or smart locks.

As a result, homeowners should look into choosing an option with a solid warranty. It’ll provide a way of getting a replacement or refund when those unfortunate incidents do occur. I can’t tell you the number of times that these plans ended up saving me.

Other Important Factors to Consider


But those factors aren’t the only ones worth considering during this process. You’ll need a handle on several background topics to choose the best biometric door lock. So here’s a quick overview of crucial, much-needed information for potential buyers.

What are biometric door locks? How does it work?

These door locks utilize personal, identifiable information to unlock doors instead of keys. These devices will usually use an optical or thermal scanner to store your fingerprints. Once the scanner recognizes your fingerprint, it’ll ask you to input a PIN to unlock the door.

It ends up allowing people to use their fingers when unlocking doors inside or outside their homes. Therefore, it’s much more convenient than relying on and keeping track of keys. But it’s worth noting that most biometric locks do come with a physical key when an issue does occur.

What are the different types of biometric door locks?

Most homeowners are familiar with biometric fingerprint scanner locks. After all, these locks are available on our phones while also commonplace in businesses and homes. But these aren’t the only types of biometric locks.

  • Biometric Hand and Vein Geometry Door Locks

There’s more than one way to use your palm or finger as a door key. As you know, a biometric fingerprint door lock uses unique patterns and impressions on our fingertips to recognize people. Hand geometry can make a hand scanner door lock by using our finger lengths, palms, and other identifiers.

Meanwhile, vein geometry will use the unique placement of your hand’s veins to identify you. Then, it’ll release an electromagnetic light into your skin, where it’s absorbed and takes a picture. It’s a relatively cool way of unlocking a door and entering your home.

  • Biometric Voice Door Locks

Voice control recognition technology is a widespread tool used in our society. So it shouldn’t be too shocking to learn that it’s utilized in biometric smart door locks, as well. The technology itself works by breaking down your speech’s audio components to identify you.

But how does it do it? Well, studying speech and linguistics is a lot more complex than most people realize. However, think about your voice as emitting small vibrations whenever you say something.

These vibrations occur at different wavelengths, which create patterns. Voice recognition technology processes your specific patterns to identify you.

  • Biometric Iris and Retina Door Locks

Your eyes can be a unique way to identify each person, as well. For example, certain biometric security locks will function by scanning your retina and iris as an extra safety precaution. The process relies on low levels of infrared light being absorbed into your eye to reveal the iris and retina’s unique patterns.

Why do you need biometric door locks?

These door locks offer certain benefits that key locks don’t provide. This section will discuss some of these advantages in more detail. In other words, it’ll offer a better idea about whether these devices are suitable for your needs.

  • Better Security

Most traditional locks don’t offer enough resistance or protection against a determined thief. For instance, doorknobs are extremely easy to pick. One strong kick to the door can even be enough force to break the knob’s latch, making your valuables easy pickings.

Moreover, most people can get the job done with a paperclip and a hairpin. It just becomes a simple matter of doing some internet research, and unlocking a doorknob is a breeze. Deadbolts, combination locks, and padlocks are better but still suffer from being breakable.

Honestly, seasoned crooks won’t sweat these locks and breakthrough them with ease. Biometric smart door locks are different stories, though, as they’re much more durable and high-quality than these other lock types.

  • Don’t Require a Password or Key

Let’s be honest: passwords and keys are a pain. Biometric locks don’t require either as the unlocking mechanism is a part of your body, such as a finger or eye. In addition, it removes the need for remembering anything, which is ideal for a forgetful person like me.

It’s worth noting that some biometric locks do require a PIN. But even these are much easier than remembering some lengthy combination or keeping track of a key. So it makes them a lot more convenient, especially when installed on a door.

  • Duplicating Them is Much More Difficult

Although a fingerprint lock isn’t immune to duplication, it does require a lot of work. No amateur can bypass it like they could with doorknobs or a combination lock. In fact, there are only three ways a fingerprint can be duplicated.

The first method is someone making a mold of your unique fingerprint. It’s a possible action when a person physically lifts your fingerprints from a locking device. From there, they’d have to transfer them onto a skin-like material, which is a lot of work.

Researchers in Germany duplicated a fingerprint from a high-resolution picture and created their dummy finger using a 3-D printer. The last method would be hacking a government agency and stealing the fingerprint data on file.

  • Offers More Control

Biometric locks are superior to other types when it comes to control. In other words, they offer excessive amounts of traceability about who comes into and out of your home. Parents will never have to worry about whether their kids were home when they said or not.

After all, the lock’s administrators can track who used your door and at what time. They can also help keep your child safer when you’re away by offering better protection. Therefore, fingerprint or thumbprint door locks are a parent’s dream device.

Businesses could benefit from biometric locks, as well. These devices can easily track employee start and leaving times while keeping valuables protected. Buying them ends up being a no-brainer for anyone capable of affording them.

Frequently Asked Questions


Everything up to this point has given a picture of your perfect door lock offers. Our FAQ section will help focus that picture even more and make it clearer. It’ll fill in any gaps left in the knowledge needed to choose the correct option.
