Buying Guide: Best Fingerprint Door Lock

The following considerations must be taken into account when purchasing a fingerprint door lock:

Basic Function

Regardless of how sophisticated and elegant the biometric fingerprint door lock is, you always need to prioritize its main function.

The fingerprints of adults and children must be detected quickly and rapidly. In addition, thesensitivity of the sensors must work well. Too much effort to open it destroys the intention of getting a fingerprint door lock. Therefore, please check the response time of the system.


One of the major factors is that your door must be highly durable. You don’t want to buy a perfect bolt that lasts for a short period. The material used for making it is what you need to verify.


Search for stainless steel locks, zinc alloys, aluminum alloy, etc. This should also secure your safety when someone attempts to temper it from outside. The building material must be water-resistant, resistant to corrosion, etc. so that it will last in different weather conditions if you intend to mount your Fingerprint lock outside.

Several Fingerprints

So, buy a lock that provides multiple fingerprint systems. It will provide you the multi advantages.

Screen Type: LCD

It is also helpful to have an LCD displaying time, access attempts, and a review of why you could not access a given effort. A stoic metal piece with no indices but beeps and blinker lights are, in any case, surprisingly unhelpful.

Low False Rejection Rate (FRR)

Technology will not always be accurate. It has some flaws, and a biometric system with a low reject rate will be the primary target. It is significant for a fingerprint lock.

How Fingerprint Door Lock Works?

Until recently, technology has turned the world’s keyed locks into tomorrow’s electronic door. Is it safe to lock doors electronically? Electronic locks provide more security compared to regular door locks. Let’s see how it works:

  • All right, now let’s get to the actual workings of these locks. Fingerprint locks are scanned and converted to a numerical template by your fingerprint information.
  • First, the finger is placed on the scanner.When the fingerprint template is saved,it will be converted into numerical data. Any time you give someone an entry, this process is repeated.
  • The second time that a finger is placed on the sensor, the data collected by the finger matches the values previously saved.
  • On the other side, if entry is not permitted, the door stays locked if someone else tries to reach it.
  • The most critical step here is to fit the algorithm. Typically, this is accomplished by minutia matching. Several minute points, location, and direction are located on your finger pads when you log. This is stored in your memory.
  • The fingerprint prototype already stored is compared to the current fingerprint scanned during this process. If a match happens, it is normally indicated by a green LED and will open the door.
  • The method is really quick and finishes in a split second.

Final Verdict

So were you able to find the best fingerprint door lock? We have discussed above the top 5 finger lock. We will first suggest the Sifely Fingerprint Entry Door Lock and then ULTRALOQ UL3 Latch edition if you ask for our recommendation.
