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 the fingerprint capacity. Biometric models work with fingerprints instead of keys. In fact, they work by scanning your fingerprints to identify its unique structure. You may be surprised to discover that they have a 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 especially if you need to replace your old unit and you have to drill new holes. The usual dimensions for these units are 44mm and 60 mm. There are also other dimensions, such as 50mm, but these are rarer.

  • 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 which can work 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 the 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 store 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 use 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 really like about these devices is that in case something happens with your key fob or with your smartphone, they use a secondary means of electronic entry.

Frequently Asked Questions



1Are 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.
2Are fingerprints locks more secure than regular deadbolts ?
They are high-tech security systems for homes and offices. They allow you to go in and out of your house without being forced to search for your keys. They use biometric systems with multiple sensors to identify a person based on specific characteristics, including fingerprints.

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

4 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.

5Does 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.

6Can they 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 use 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.

7What 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 completely 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.

8How long do batteries usually last in these 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.

9How many fingerprints can be stored?
The number is variable. Some locks can memorize and store one hundred fingerprints while others can handle two hundred fingerprints. On average, a unit of this type can store up to 150 distinct fingerprints.

10Can 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 delete other fingerprints.



Conclusion

After hundreds of reviews about some of the most advanced and impressive security systems, we can truly confirm that biometric recognition is among the greatest options out there. As 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 unique fingerprints to memory, which is extremely helpful in situations where family members or close friends are constantly coming and going.
