  • The gate can represent a weak point in your security system, so make sure it always stays locked with a gate opener. Yes, it may sound counterintuitive, but these devices, besides making your life easier and opening the gate for you on cold winter days or extremely hot afternoons, have great locks that require advanced authentication methods.

  • Override key – the third identification method works as a backup in case the key runs out of battery.
  • Double identification – you can set it to require both biometric and card verification and thus upgrade the security level.

11. HARFO HL1

Check Price at Amazon


Specifications

  • Application type: Interior
  • Authentication: Fingerprint only
  • Max User Memory: Up to 100 users
  • Door thickness: 35-55mm, 60mm and 70mm
  • Power: Built-in Li-ion battery
  • Battery Life: 1 year
  • Charging time: 30 min.
  • Warranty: 1 year


This product only looks simple, but the truth is that there’s quite an advanced technology behind it, which helps keep things uncomplicated and allows this device to function flawlessly every time it is used. At first sight, it doesn’t even look like you are using an advanced lock, as this model looks a lot like a regular door handle. Nonetheless, once you take a closer look, you will observe the fingerprint scanner along with three LED indicators designed to signal the unit’s functioning.

  • Advanced fingerprint scanner – it only takes a second for the scanner to wake up, read the print and unlock the door. It is highly accurate, and according to the users who got to test it, the cases in which it doesn’t identify the print are rather rare.
  • No duplicate fingerprint reading – it only reads real prints, so silicone copies will not trigger the mechanism to unlock.
  • Add or delete fingerprints – the process is pretty simple, as you will only need to use the pin to press the option button and register new fingerprints. The same goes for deleting them. The first registered user is recorded as the administrator, but the operation of adding or removing new users isn’t limited to them. This is a bit of a downside, as every user can operate the registry, so you will need to trust all the persons who have access.
  • Lithium-ion battery – unlike other models that have disposable AA batteries, this device comes with a built-in Li-ion battery, which only needs 30 minutes of charging to operate for a whole year. The USB port is placed on the exterior side of the lock, so it can also work as an emergency power source in case the battery is dead. In this case, you just need to connect the lock to a power bank via USB and transfer it enough power so you can scan your print.
  • Auto-locking – no need to fret if you haven’t locked the door behind you, as this model does it automatically after 3 seconds.

The installation is super easy, seeing how it matches almost all standard US doors, and there’s no need to do any drilling or wiring. Two screws are all it takes to get it in place. The warranty extends over 1 year from the date of the acquisition.

PROS

  • Green energy – Li-ion battery
  • Installs in minutes, and the setup is quite straightforward
  • First-rate scanner recognizes the prints almost every time and cannot be fooled by silicone prints
  • Locks automatically after 3 seconds to prevent intrusions

CONS

  • Adding and removing users isn’t restricted to admin only
  • No backup identification methods, so if the scanner fails you may remain locked on the outside

Verdict

With this model, you get a simple and elegant way of keeping your entrance protected. There’s no need to enter a code or use a card, which are less reliable authentication methods. Conversely, the biometric scanner is accurate and will grant you access every time without having to carry a key in your pocket.

  • Door thickness: 1-1/4″ to 2-1/4″

When it comes to security, this model is among the most dependable ones, if we regard both its access mechanism and powerful structure that cannot be easily broken. The exterior chassis has a double shell with heavy-duty construction that guarantees its durability even if it is used tens of times per day. The lock is conceived to be installed on doors that are as thick as 1-1/4” to 2-1/4”, and despite its robust design, it can only be installed inside as it isn’t weatherproof.

  • Self-learning – it is great at reading fingerprints and this is due to its ability to constantly upgrade its recording.

In time, this system leads to almost no fails in authentication through this method.
  • Key and code – it integrates a keypad so you can create a code for each user if you prefer this method.

  • Great user storage capacityup to 100 users and fingerprints is all you need to install this device on any residential or office door.
  • Restricted programming access – another design aspect that cannot be overlooked is that only the administrator can have access to creating new users or deleting the existing ones, either through a special code or fingerprint. Thus, the risk of one user deleting all the users and leaving the door open to everyone or allowing access to other persons who were not approved by the administrator is nonexistent.

You can mount it either on the left or on the right, depending on how your door is projected to open, as the handle is adaptable. The process goes smoothly, and if you by chance get puzzled by the instructions included in the package, you can check the manufacturer’s website for more details.

It can be mounted on a door that is as thick as 1-1/5” to 2-2/5” and comes with an irreversible handle that opens on the right, so there’s not too much room for adjustments here. On the other hand, there’s one good reason for which the handle cannot be reversed. Namely, to improve its overall durability. The results show, as this handle is estimated to resist up to 600,000 uses.

  • Extra-large user memory – this model is an excellent fit for large businesses, considering that it can store up to 200 users, divided as follows: 10 administrators – have the permission to create new accounts and delete the already existing ones; 140 regular users – can use one of the authentication methods to open the lock; temporary users – can use a special code that will grant them access only for a certain time interval or in certain days.
  • Combination mode available – if you are planning to install it on a door that guards important documents or belongings, you can opt for this mode, which requires two persons to be present when unlocking the door.

A truly dependable model that can be used both for interior and exterior doors, it is the right pick for a business place due to its large user storage and state-of-the-art fingerprint scanner. Moreover, as access can be restricted depending on the user’s level, it would work flawlessly for a laboratory, where 2-user authentication is desirable.



6. hornbill Smart Lock Deadbolt

Check Price at Amazon


Specifications

  • Application type: Interior/Exterior
  • Authentication: 5-in-1 Keyless Lock
  • Fingerprint: 100 fingerprints, 150 codes
  • Max User Memory: 100 users
  • Door thickness: 1-1/2” to 1-7/8”
  • Power: 4 AA batteries
  • Battery Life: Up to 1 year of use
  • Type of Fingerprint Sensor: N/A
  • Warranty: 1 year


A popular model due to its weatherproof construction that allows installing it on an exterior door as well as on an interior one, the hornbill in our top surprises through a series of qualities that place it among the most dependable models at the moment. To put it short, it would be pretty difficult to overpass this security system, and here’s why:

  • Strong fingerprint sensor – it quickly reads the fingerprints and has a high identification rate, so the chances of it giving a false negative are slim. Conversely, the chances of it giving a false positive are even slimmer, as the technology used is almost impossible to trick.
  • Local data storage – all the passwords and fingerprints are stored locally and not in a cloud. Thus, they remain private, and no one can have access to them, so your house will stay safe.
  • TTLock App – to pair this model with a smartphone, you will need to acquire a Wi-Fi gateway, which is sold separately by hornbill. Is this investment worth the money? It can be if you need to generate different types of codes remotely and want to stay in touch with what’s happening at your house. Furthermore, a Wi-Fi connection will allow you to use Alexa or Google home to operate the device.
  • Create different types of codes – you can create regular codes, which will grant access to the users every hour from day and night. Nonetheless, there are special codes that can be generated to be used with this device. For instance, you can create a one-time use code, which, as the name says, will let the user unlock the door once. Other codes can grant access only on pre-established days and at pre-established hours. Moreover, you can generate a code that can be active only for several hours and then become inactive.
  • E-keys – another authentication method, it allows you to generate a virtual key that can only be used with the applications. The users will need to download the app and install it on their devices to open the door. The cod will not work if inputted through the keyboard.
  • Auto-locking – the lock bolts on its own if it detects that the door is shut, so you can always be certain that intruders cannot use an opportunity to enter your house.
  • Anti-peep – Just like other advanced models, it allows inputting several numbers before or after the cipher so no one can know what your actual code is.

Besides the unlocking methods we have already enumerated, this model accepts a mechanical key as well, which can be used in emergencies. Moreover, in case it runs out of power (you may forget to replace the batteries on time), it has a backup port that will allow you to use a 9V battery to power it and get access inside the house.

PROS

  • Offers 5 methods of unbolting the door
  • Can be operated remotely with the help of the TTLock app
  • The app allows you to generate different codes that can serve particular purposes
  • Strong construction makes it fit for exterior use
  • Locks automatically if it senses that the door is shut

CONS

  • You need to acquire a separate hub to be able to use the app or voice command
  • Some customers complained that the installation instructions are unclear and difficult to follow

Verdict

This is a nice investment as it is, but if you want to make it great, we recommend acquiring the Wi-Fi gateway. Internet access will allow you to use your smartphone to create codes and virtual keys, as well as follow who is entering and exiting the door. It is a solid model that can be mounted on an exterior door and offers improved data protection as all the fingerprints and codes are stored locally.

Specifications

  • Application type: Interior/Exterior
  • Authentication: 5-in-1 Keyless Lock
  • Fingerprint: 95 fingerprints, 95 codes
  • Door thickness: 1-3/8″~1-3/4″
  • Power: 3 AA batteries
  • Battery Life: Up to 8,000 times access
  • Type of Fingerprint Sensor: Auto Wakeup Fingerprint Sensor
  • Warranty: 18 months electronic warranty; Lifetime mechanical warranty


The Ultraloq is already a famous name in the door security industry so, from the start, it is expected that it will deliver a high-quality product. The UL3 BT features a time-resistant structure and is one of those infallible systems customers fall in love with and to which they remain loyal. It can be mounted on most doors with a thickness between 1-3/8” and 1-3/4”, and the only thing that is necessary for the installation – a screwdriver – is included in the package.

  • Hardwearing sensor – it is dustproof and waterproof as well as scratchproof, so it will resist areas with high traffic and maintain its performance over time. However, note that the manufacturer recommends for it to be used on interior doors only, as direct sunlight and extreme temperatures may cause it to malfunction.
  • Many unlocking options – you’ve got the fingerprint and the code, which are most common in the devices we’ve selected, but what’s truly interesting is that you can unbolt the door by knocking on your smartphone 4 times, in case you have an iOS system. If you have an Android phone, you only need to wake the screen and shake the phone. This unit also includes a physical key.
  • Up to 95 print memory – register up to 95 users with their unique fingerprints. Perfect for a large residence or an office building.
  • Quick authentication – The scanner doesn’t need more than 0.5 seconds to identify a print and grant access to the user. If the lock is mounted in a highly-trafficked area, this is a true bonus, as it won’t slow the circulation of the employees.
  • No peeping – strangers won’t be able to tell which is your code, as you can insert random digits on the keypad before or after entering the correct cipher.
  • Passage – you can activate this mode if, for a while, you want to allow access to everybody who is entering the door. This mode can be used if you are hosting an event or if your business needs to allow access to customers during program hours.
  • Lockout – this mode quickly blocks all the codes and other authentication methods, allowing access only to the admin.

Every time the door is closed, an integrated sensor transmits the information to the lock, which latches automatically. Regarding connectivity, this model uses Bluetooth for the “knock” and “shake” functions, but it can also connect to an App through Wi-Fi and offer you access to the entry registry and control over user creation and deletion.

PROS

  • Quick fingerprint scanner reads a print in under 0.5 seconds
  • Multiple modes allow customizing the lock’s operation
  • Smartphone connectivity allows unbolting the door from the distance
  • The sensor is resistant to wear, so it will preserve its performance over time
  • Can store up to 95 users

CONS

  • The Bluetooth connectivity is not reliable all the time
  • There were reports regarding issues registering some fingerprints

Verdict

If you are thinking about trading your old unit and buy a smart one to secure your home, this is exactly what you need. It is a modern model that uses cutting-edge technology and comes equipped with an excess of impressive features. It has a powerful scanner that will quickly identify the print and will remain just as performant over time, considering that it was treated to resist dust, water, and scratches.

3. Lockly Fingerprint PGD728F

Check Price at Amazon


Specifications

  • Application type: Interior
  • Authentication: Bluetooth, Access code, Key, Fingerprint
  • Type of Fingerprint Sensor: 3D fingerprint sensor security
  • Access code: 6-8 digits
  • Fingerprint: up to 99 fingerprints
  • Door thickness: 1 3/8″ to 2″ thick
  • Power: 4 AA Alkaline batteries
  • Battery Life: 9 months – 1 year
  • Warranty: 2 years electronic warranty; Lifetime mechanical warranty


Gain entrance with a simple touch of the finger. If you don’t feel like it, use your phone and access the entry point through Bluetooth. If none of the above possibilities sound appealing, you can get in by inserting the 6 to 8 digit ciphers. The Lockly Fingerprint PGD728F is the ultimate pick when it comes to home security due to its top-notch reading algorithms and supplementary protection options.

  • 3D fingerprint reading – it is impossible for a fake print to trick this device, and this is only possible due to the integrated 3D scanner, which creates print templates by using electrical current and capacitors and is incapable of reading a lifted or silicone print. The technology is incredibly accurate as well, so it will read the prints correctly almost every time the user tries to unbolt the door.
  • Original peek-proof system – the digits are displayed in groups of three and, once you have introduced the code, the screen will instantly shuffle them, so possible intruders cannot figure out which digits you’ve pressed.
  • Alarm system – if someone is trying to overpass your protection system, it will activate a loud alarm to let you know about the possible breach.
  • Extra protection – if the code is introduced wrongfully three times in a row, the keypad becomes inaccessible. To unlock it, you will need to input the right code two times in a row.
  • App compatibility – the unit presents Bluetooth compatibility, so you can download the app on your phone and unlock the door just by tapping on the screen. With the app, you can get access to the entry history as well and create new codes remotely, but this is only possible with a Wi-Fi hub that needs to be purchased separately.
  • Backup power supply – the AA batteries are included in the package, so you will just need to fit them in their compartment to power the device. A backup port is also available, in case you fail to replace them on time, so you will be able to unlock the door by connecting a 9V battery.

The unit comes with a comprehensive instruction manual that will guide you through every step of the installation and programming process. It is compatible with doors that have a thickness of 1-3/8” to 2”. It is backed by a 2-year service assurance for the electronic parts and a limited lifetime warranty for the mechanicals.

PROS

  • Uses a last-generation scanner that cannot be tricked with fake fingerprints
  • Extra protection mechanisms – alarm and keyboard lock
  • Shuffling keyboard prevents strangers from finding your code
  • The battery can last up to 1 year before requiring a charge
  • Great service assurance

CONS

  • The alarm seems to be a bit too sensitive
  • The customer service takes a lot to respond

Verdict

One of the most dependable options on the market, packed with multiple protection mechanisms and using one of the most advanced scanners, the Lockly Fingerprint is worth every penny. The shuffling keyboard helps keep your cipher secret while the alarm will scare off any intruder. Plus, it comes with a great warranty, but you will need to have a bit of patience as the customer service team isn’t the fastest.

It is easy to tell from the first look that the Samsung Digital SHS-P718 is different from all the locks available for sale at the moment.

The touch keypad is sleek, and the fingerprint scanner positioned at the top and protected by a cover is expected to maintain its performance even if the device is mounted on an exterior door. Besides all these, the technology behind the design is innovative, and this model packs a lot of features designed to upgrade security and make its use more convenient.

Design Highlights

This is a sleek, luxurious model that will match most standard American doors. Just make sure to pay a little attention to the thickness of your door, as it should be somewhere between 38 and 80 mm for the device to fit properly.

  • DIY installation – even if it is a more complex system, the installation is doable without the assistance of a professional. The instructions that come in the package are detailed and comprehensive so, by following them step by step, you will be able to mount the device yourself.

  • Easy-read interface – you will know at all times if the door is bolted or unbolted as the display shows messages letting you know about its status. Thus, there’s no room for confusion as it is with other models, which use LEDs instead of text messages.

Advanced Security Features

Once you’ve closed the door, the device locks on its own to prevent intrusions, so you can rest assured that, no matter if you are at home or away, the door is always secured. Nevertheless, if this option is quite common in fingerprint locks, this model offers other interesting options, so let’s take a quick look at them.

  • Hack-proof construction – the handle and the body were consolidated to form a compact and though structure that makes breaches through force difficult, so this unit isn’t easy to break.

How We Rated these Models


Over the past few years, smart locks have become every homeowner’s favorite. Although they offer the same level of security as typical mechanical locks, they are much easier to mount and most of them are equipped with more features than standard locks. These incredible systems are designed to change our lifestyle, making us witnesses to a new digital era of keyless locking.

  • Fingerprint capacity

    Among the essential things to consider is fingerprint capacity. Biometric models work with fingerprints instead of keys. They work by scanning your fingerprints to identify their unique structure. You may be surprised to discover that they have a maximum fingerprint capacity. This represents the number of fingerprints that can be saved into memory. While most locks come with a capacity of one hundred users, some models can store more than 100 fingerprints. Take a look at the Itouchless and you will be pleasantly surprised to discover that it has a 150 fingerprint capacity.

  • Door thickness

    If you are thinking about installing a protection system, pay special attention to the door measurements. While the residential exterior doors are 1-3/4” thick, the interior doors are usually 1-3/8” thick.

  • Backset

    The backseat is the space between the center of the keyhole and the margin of the door. This is essential particularly if you need to substitute your old unit and you have to drill new holes. The usual dimensions for these units are 44mm and 60 mm.

  • PIN codes

    Digital locks use a numerical code for authentication. They typically use combination numbers between 4 and 12 digits. Also, these types of bolts do not require users to use any key to gain access. While some locks use PIN codes instead of standard keys, other models use a proximity card for authentication. However, as mentioned above, the most advanced models use a person’s physical unique characteristics such as a fingerprint, eye scan, and even voice to verify their identity.

  • Battery

    Since these devices continue to grow in popularity due to their high level of efficiency and convenience, you should not be surprised that the market is overflowing with a broad array of types and models. The most sophisticated models use AA alkaline batteries that can operate for approximately 12 months, which means almost 10 times per day. Also, most of these models come with a battery indicator that announces the user when the battery is getting low.


Entry Methods


If you are familiar with these security systems, then you probably know that the most advanced electronic locks feature more than one means of entry, such as RFID, fingerprint, Bluetooth, or keypad.

  • The RFID locks are created with convenience in mind. They use a card or a key fob for entry. This is a great and easy way to open your door. Do you remember those days fumbling in the dark trying to find your keys in your purse? Now, those days are gone. With RFID technology, you can bolt and unbolt the door without having to remove the card from your pocket.
  • The biometric entry is based on fingerprint identification. All you have to do is to program your fingerprint and the device will memorize it. While some models can stock up to 100, you can also find devices with a larger capacity that can store up to 150 fingerprints. Also, keep in mind that if a fingerprint is not memorized, the system will not lock or unlock the door.
  • While some electronic units utilize fingerprints to unbolt the door, others use keypads with a pin combination for entry. The most advanced models use touch panels and are equipped with a plethora of security features to prevent burglars from finding the combination code.
  • The Bluetooth locks are similar to the RFID locks. They operate similarly, opening the door when you approach. What we like about these devices is that in case something happens with your key fob or with your smartphone, they utilize a secondary means of electronic entry.

Frequently Asked Questions



Are all the above models for both indoor and outdoor use?
Unfortunately, not all the models are water-resistant, so it is not advised to install them on an exterior door. Plus, you shouldn’t operate them with wet hands as they might malfunction or be damaged. In general, the water-resistant models are fit for both the inside and outside doors.

Are fingerprint locks safer than regular deadbolts?
They are high-tech security systems for residences and offices. They permit you to go in and out of your house without being forced to search for your keys. They utilize biometric systems with multiple sensors to identify a person based on specific characteristics, including fingerprints. Some of them come with alarms while others connect to your phone and can send you live notifications, so they are safer in the sense that you always know what’s happening at your door.

How long do fingerprint locks last?
Smart door locks are designed to last for many years. The operating system is easy to use and doesn’t require periodic maintenance.

What is a biometric system?
The biometric system is a system that uses multiple sensors to identify the unique biological traits of a person. The system is usually used to grant access to systems and devices.

Does a fingerprint door lock work with regular keys?
Apart from fingerprints, PIN codes, and apps, it also works with regular keys in case its battery power is low.

Can fingerprint locks be hacked?
As long as the method of authentication is a fingerprint, it’s complicated for someone to break the code and steal your fingerprint. However, if you utilize a PIN code to bolt and unbolt the door, we recommend changing it once a week as the digital codes can easily be hacked and stolen.

What happens when the battery is empty?
In general, the lock will beep. The advanced models have audible warning indicators that let you know when the battery is empty. However, you can still close and open the door with the regular key. Although it is a smart device that works with digital sensors, apps, and biometric technology, it still has a spare key that can be used in these cases.

How long do batteries usually last in fingerprint door locks?
It depends on the model. For example, the Samsung Digital SHS-P718 has a battery that lasts approximately 1 year, while the Ardwolf A1’s battery works for 4 months only.

How many fingerprints can be stored?
The number is variable. Some locks can memorize and store one hundred fingerprints while others can handle two hundred thumbprints. On average, a unit of this type can store up to 150 distinct fingerprints.

Can fingerprints be deleted?
We recommend deleting user fingers periodically to avoid getting hacked. However, remember that only the administrator can do that. If you are only a guest you cannot remove other fingerprints.



Conclusion

Compared to standard locks that use regular metal keys, the biometric systems work with batteries. They ensure access by identifying and scanning a person’s unique identification, such as a fingerprint. The fingerprint is the main form of identification. Once it is scanned by the lock, it is stored in a database. Most of the models available on the market store up to 150 matchless fingerprints to memory, which is extremely helpful in situations where family members or close friends are constantly coming and going.

The models we’ve selected match the highest standards when it comes to security and convenience. Nonetheless, some of them come with more authentication methods, and some include amazing features, so don’t hesitate to take a second look at our best selections.
