What is a Biometric Door Lock?

Biometric door locks use personally identifiable information instead of the traditional key. They use a thermal or optical scanner to keep the fingerprints of authorized persons. When the scanner detects you as an authorized user, it prompts you to enter a PIN to unlock the door. These locks are designed for your convenience because you don’t need to keep track of the key, not just added security. However, they do come with a fail-safe key if the batteries or electricity that power the lock fail.

To simplify, a biometric lock is one kind of smart lock that’ll use a combination of fingerprints from authorized users with a variety of PINS to unlock your door.

Are Biometric Door Locks Secure?

The security of any smart lock depends on the quality of its hardware and software. If a biometric lock is easy to break physically, it doesn’t provide greater security than a traditional lock. 

If the software embedded in the digital lock is flawed, hackers could take advantage of that flaw to unlock your door. Because smart locks usually come with a physical key, if you forget your PIN or the power to the lock goes out, anyone who has the key can enter.

So if you choose a good quality biometric lock that provides high security, they will have the superior hand from traditional locks. 

Why Should You Get It?

A keyed door is time-consuming to access, especially when you need the door to be accessed by multiple users. A biometric lock is your solution to that. You don’t need to keep track of your key, and you can go through the door without disturbing anyone or losing much time. 

Lockless doors are convenient but unsafe, and traditional keyed doors are safe but inconvenient. Biometric door locks offer both, giving access only to authorized personnel without locking and unlocking the door each time. Biometric door locks for offices are a perfect example of high traffic entrances that need security without disturbing people. 

Fingerprint scanners used to be a fantastic thing or accessible only to those with a lot of money to spend. Prices for fingerprint locks can go down with each passing year, but these devices still can “wow” people when they first see them. 

Alternative to Biometric Door Locks 

There are other smart locks excluding biometric doors that offer pretty solid security. Smart locks can be controlled with your phone via wireless connectivity. Some of them use Bluetooth connectivity. Multiple users can be authorized and access the door with their phone. 

Another variety in door locks is a touchscreen lock. You can access your door by inserting a PIN you set earlier on a touch screen. These locks come cheaper than a biometric lock and will provide you a modest amount of security with convenience. After all, they’ve all moved on from the traditional key system.

Features of a Biometric Lock

Biometric locks have features making them different from traditional and other smart locks. Not all of them will be overloaded with the same features, but they all have some common characteristics that make people want them installed. 

Quick and easy access. Unlike other locks, you can go through biometric doors in seconds. No jiggling keys to open a door sure saves a lot of time. Provide your fingerprint, and you’re set. 

Multiple user access. If you install them at home, all family members don’t need individual keys. Authorize everyone’s fingerprint, and you get a hassle-free system. 

A smart option for an office environment. Biometric door locks for business or office can make the best of these locks. They boost office security and only provide access to authorized personnel. Moreover, when someone leaves the company, no need to change the locks. Only deleting particular fingerprints will suffice. 

Easy installation. Most of the locks are easy to install. Some may require a complicated process but nothing you can’t do on your own. 

Multiple unlocking systems. With a traditional keyed door, you can only open your door using a metal key. But with biometric locks, you can either access the door with your fingerprint, use a pin code or, with your phone. Upgrading from a single method to open a door is one reason why users prefer biometric locks. 

Advanced features. Some of them introduce some very advanced features to make your experience smooth and convenient. For example, automatically unlock by accessing location, remote unlocking, voice command access, instant lock, automatic lock, Alexa and Google compatibility, double verification, and much more. 

How to Install a Biometric Door Lock

Installing a biometric door lock differs from lock to lock. Every lock can require a different installation process. But the most basic one is-

Step-1: Remove your old lock using the necessary tools. You probably won’t need anything more than a screwdriver that suits your door lock screws.

Step-2: Put the new lock in the vacant space your old lock was and screw it to the door. If you’re installing it to a new door or keeping your old one while adding this, you may need to drill new holes. 

Step-3: Program your fingerprints and add a pin code to your lock. Then connect the lock with your mobile and access everything else necessary to complete the installation. 

To sum up, install a biometric lock the same way you’ll install an ordinary lock and program the compatible features. If you are uncomfortable installing the lock or don’t have the tools, you always ask a professional for help.  


Is it hard to install biometric door locks?

No, biometric locks aren’t hard to install. Most of them are designed to be installed by users. Some of them may require advanced knowledge. 

Is a biometric door lock hackable?

The biometric aspect, i.e., your fingerprint, is not hackable. But the locks also contain pin codes that can be hacked. 

Final Words

To sum up, your priority decides which lock takes the cake. Different biometric locks come with different areas of expertise, providing exquisite features. Depending on your preference, you can go for any of them from the list. If not picked sensibly, a biometric door can cost you a lot of money without fulfilling any of your expectations.

Do your research before spending a fair amount of money. More than that, never compromise where your safety is at stake.
