How We Rated these Models

Over the past few years, the 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 install and most of them are equipped with more features than standard locks. These incredible security systems are made to change our lifestyle, making us witnesses to a new digital era of keyless locking.

  • Fingerprint capacity

    One of the most important things to consider when purchasing a digital lock is the fingerprint capacity. Biometric locks work with fingerprints instead of keys. In fact, they work by scanning your fingerprints in order 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 the memory. While most locks come with a capacity of 100 users, there are also models that are able to store more than 100 fingerprints. Take a look at the Itouchless Bio-Matic model and you will be pleasantly surprised to discover that it has a 150 fingerprint capacity.

  • Door thickness

    If you are thinking about installing a security 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 distance between the center of the keyhole and the edge of the door. This is extremely important especially if you need to replace your old lock and you have to drill new holes. The common sizes for door locks are 44mm and 60 mm. There are also other measurements, such as 50mm, but these are much less common.

  • PIN codes

    Digital locks use a numerical code for authentication. They typically use combination numbers between 4 and 12 digits. Also, these types of locks 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 characteristic such as a fingerprint, eye scan, and even voice to verify their identity.

  • Battery

    Since the digital locks 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 advanced models use AA alkaline batteries which are able to work approximately 12 months, which means almost 10 times per day. Also, most of these models come with a battery indicator which 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 (Radio Frequency Identification) locks are designed 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 lock and unlock 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 are able to store up to 100, you can also find devices with a larger capacity which 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 locks use fingerprints to unlock the door, others use keypads with a pin combination for entry. The most advanced models use touchscreen panels and are equipped with a plethora of security features in order to prevent burglars from finding the combination code.
  • The Bluetooth locks are similar to the RFID locks. They operate in a similar way, 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.

After hundreds of reviews about some of the most advanced and impressive security systems, we can truly confirm that the biometric recognition is the most popular option out there. It is one of the most advanced and impressive technologies and it is certainly an option to keep in mind when considering the safety of your home. As compared to standard locks which use metal keys, the biometric locks are battery-powered security options that 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.
