Fingerprint Door Lock Buying Guide


Biometric fingerprint door locks are a great way to secure your home. However, before purchasing one, make sure that it has the ability to detect fingerprints from adults and children quickly and efficiently so you can avoid having frustrated family members unable to leave or enter your home. 

Additionally, make sure the lock is easy enough for people of all ages to operate on their own without frustration.


The locks that keep your home secured are just as important, if not more so, than the type of lock you use on your door. The key to a sturdy lock is one made out of durable materials like stainless steel or zinc alloy. 

You don’t want to purchase a high-quality lock only to have it break after an hour. If you plan on installing it outdoors, you’ll need to take precautions for the material that can withstand rain and other weather conditions.

What is a biometric door lock?

The best way to protect your home is with a biometric door lock. This type of lock uses fingerprints for access instead of the traditional keys that we all have gotten used to carrying around on our keychains these days.

All you need are some thermal or optical scanners and an authorized fingerprint, then voila. Smart locks also come equipped with fail-safe keys so there can always be some way around entering through these locked doors even without batteries or power from electricity.

How does a biometric door lock work?

When you place your finger on the scanner for the first time, it immediately converts into numerical data and saves a fingerprint template. This process is then repeated every single time anyone wants to grant access.

The next person will have their fingerprints scanned and matched with pre-saved values in order to match them up correctly.

Biometric locks are among the most secure smart lock options. They require your physical presence to unlock, which means that anyone trying to break in would have no way around them without a key or fingerprint scanner.

This makes them great for security-conscious families and businesses. We’re going to highlight three types below.

  • Keypad locks: Keypad locks are a more secure way to get inside your home. Since you have to enter a PIN, it’s harder for thieves and other unwanted guests to break in.
  • Proximity locks: Proximity locks allow you to unlock the door once a wireless key fob comes within a specified distance.
  • Wi-Fi or Bluetooth locks: With an app that you can connect wirelessly to your home, unlocking the door is as easy and quick as a click.

What to look for when buying biometric door locks?

There are so many things to consider when shopping for a biometric door lock. These factors include the number of different codes you want, how easy it is to enter and exit your home and whether or not you’ll be using this on an existing deadbolt that needs modifications.

Low battery warning

The battery in your lock may be low at any given time, so it’s important to stay aware of the state of your power source and avoid being locked out.


Many models do not require hard wiring for installation. That said, there’s always a chance of losing your fingerprint data if you experience power outages or system malfunctions especially now that we’re transitioning from wifi-based systems.

Make sure to get one equipped with backup batteries so you won’t have any worries about security issues during these unfortunate events.

Multiple Fingerprints

Make sure that the fingerprint lock you buy can recognize multiple fingerprints. 

LCD Display

An LCD display showing time, access attempts, and a readout of why you didn’t get access on a given try is also very helpful.

Built-in alarm 

For added peace of mind, an alarm system that chirps when the door opens can be helpful.

Mechanical Key

If the power goes out, traditional mechanical keys are still able to open doors.

Quality materials

You’ll want to choose strong materials such as titanium or steel if possible because they are much harder than their counterparts and will not shatter easily from impact.

High-security encryption

If you want to be sure your smart lock can’t be hacked remotely, look for one with high encryption. This will ensure that no matter what happens outside of the house, nobody is going to get into it. These locks go through rigorous safety testing and they’re also tested against theft- so if you find a compatible Wi-Fi model then make sure it has standard encryption protocols in place.

Access mechanisms

You’ve got two options with these smart locks: fingerprint scanners or digital keypads. With the ability to store up to 100 fingerprints and digits, they’re great for keeping your privacy safe from prying eyes!

Are fingerprint door locks secure?

It’s important that you keep your smart lock up to date with the latest software updates so hackers can’t take advantage of any vulnerabilities. You should also double-check and make sure locks are secure by resisting physical attacks on them before considering using a digital locking system in case it has an error. 

People often think that burglars enter through the front door. The truth is, most of them don’t even try to go in from there and instead search for a back door or window they can force open.

Smart locks are great because you get convenience by choosing who has access to your home. Just make sure it’s not too many people.


When installing a smart door lock, it is important to know that not all models are water-resistant. It’s also advised that you don’t install them on exterior doors because they might malfunction or get damaged by excessive exposure to rain and moisture outside in the elements.

Are fingerprint door locks secure?

The latest smart door locks make it easier than ever to go in and out of your house without fumbling through keys at the door. These new door locks let you enter your home with a simple wave of your hand, or by getting close enough to have it scanned via biometric technology when using fingerprints as identification points.

How long do fingerprint door locks last?

Smart locks are designed to run for many years thanks to the long life and low maintenance requirements. Make sure to choose a smart lock made from strong materials such as titanium or steel because they do not shatter easily from impact.

Does a fingerprint door lock work with regular keys?

Certain fingerprint door locks also work with regular keys if their battery power gets low to avoid being locked outside.

Can fingerprint door locks be hacked?

You should change your PIN code at least once a week to ensure that no one else can gain access if it’s stolen. As long as the method of authentication is a fingerprint, it’s complicated for someone to break the code and steal your fingerprint.

What happens when the battery is empty?

You can still close and open the door with a regular key, even if your lock is connected to digital sensors. The audible warning indicators on advanced models let you know when it’s time for new batteries.

How long do batteries usually last in these door locks?

Battery life is one of the most important features people look for in a fingerprint door lock. However, battery life will vary with different models. Some models can last a year while others will only last a few months before they need to be recharged.

How many fingerprints can be stored and can they be deleted?

Some locks have up to one hundred and fifty fingerprint storage capacity, while others can only handle two or three fingers at most.

It is important to periodically delete your fingers from the database to avoid being hacked into. But remember that only administrators have permission to do this- a guest can’t remove other fingerprints.

Final Thoughts

Your biometric lock is like a personal assistant. It knows you and your unique fingerprint, so it can help keep unauthorized people out of your space without the need for keys or codes.
