4 Great Fingerprint Door Locks & Deadbolts Reviewed: Biometric Security


Finding the Best Fingerprint Deadbolts and Locks

Did you know that the days of the standard house key are numbered? It's true! Technology is finally catching up and our homes will be better and more secure as a result. Biometric fingerprint deadbolts and door locks are making waves in the home security world, and they're coming your way, fast.

Recently my friend had an attempted breakin. They had used a knife or other sharp object to try to break the lock cylinder, and they came pretty close. Why are we relying on the strength of a few steel pins, when there is a better, cooler and more secure option available?

Fingerprint door locks are one of the best ways to keep you, your family and your belongings safe and secure. Rather than relying on a key that can be copied or stolen, your personal, unique fingerprint is the biometric 'key' to enter the premises. This article will look at four of the best keyless, biometric fingerprint deadbolts and door locks out there today.

Because it's a newer technology and you may not be familiar with it, I'll go over each product and give a rundown on its features, specifications and security. I'll also touch on a couple of pros and cons to upgrading. Let's begin!

Note of Caution for Keyless Biometric Deadbolts:

Before we tackle the reviews themselves, I wanted to caution you to be careful during installation. It's important that you either read the instructions carefully and test extensively when you install, or call a locksmith to have it put in properly.

Nine times out of ten, a faulty or buggy system is the result to improper installation and wiring by the home owner. If you're not feeling particularly tech savvy, let a professional put it in.

Samsung EXON: One of the better fingerprint door locks around.

When you hear the word 'Samsung', you probably associate it with televisions and smart phones. Samsung actually has a robust electronics division, including some home security.

This is a beautiful, simple and powerful home security fingerprint deadbolt and door handle that not only performs its work admirably, it looks great while doing it. It has that sleek, modern look that all the new devices tend to have, and it's built to last.

What I like about this door lock is the intelligent, thoughtful design that went into it. There are some obvious features: for example, you must press your finger against the biometric reader in order to gain access to the house. However, this is enhanced in a few ways. You can do a combination of fingerprint and key code. The keypad even has a 'magic number' feature (where you press two random numbers before entering the pin) that prevents thieves from looking at the fingerprints on the pad to learn your pin! That's smart.

It has other neat features too. For example, it can automatically detect if the ambient temperature of the residence temperature is above 60 degrees Celsius (in case of a fire) and unlocks the door and sounds an alarm for escape.

It can recognize up to 100 fingerprints, and it's easily programmable. If you ever get locked out, you can use either a 9v battery to power it up again, or an emergency override key to get in. It is a safe, secure, high tech and beautiful fingerprint door lock and deadbolt, and that's why it's at the top of my list.

Top Quality Biometric Fingerprint Door Handle & Lock by Anviz

This is a very simple, easy to install and powerful door handle and lock with fingerprint keyless entry features. It's simple enough to look great on any house and function quite normally, but it has powerful security features that make your home very difficult to enter illegitimately.

First off, the lock cylinder, the deadbolt and the housing of this sturdy biometric finger print door lock are very well constructed and heavy duty. They are resistant to any kind of brute, forced entry. It's also designed to withstand the elements, so rain and weather won't be a problem for you.

The fingerprint scanner itself stores up to 200 different fingerprints in its database, so you can give access to the whole neighbourhood if you like. The system also allows for use of an RFID tag that you can attach to a keychain. Simply pass the tag in front of the scanner and the door will unlock without a touch.

In the case of an emergency such as total power loss, you can use an auxiliary 9 volt battery and hook it up to the external battery terminal, which will provide the power to open and close the door as usual. You'll also receive a set of emergency access keys which allow you to use the door as normal manually (the keyhole is underneath and not obvious).

One really nice thing about the Anviz fingerprint deadbolt and door handle is the standardization they've used. It should work with most standard door frames, and requires only the standard single bolt hole as you'll normally find. The handle is reversible too, so it'll work anywhere.

It's inexpensive too, so it's one of the top keyless fingerprint door locks I'd recommend you check out.

NX4 Biometric: A subtle, small, motorized fingerprint deadbolt and lock for any home

If you're searching for something a little more subtle and straightforward to use, the NX4 Biometric deadbolt is a wonderful option with a lot of upside.

With no keypads or high tech stuff showing, from a distance this will look like your standard deadbolt. Lift up the nickel coated scanner cover, however, and you'll find a high tech fingerprint deadbolt lock waiting for you.

The lock is programmable for up to 99 users and their fingerprints. Programming is a simple process, and you don't have to worry about remembering passcodes anymore. Deleting a user is just as simple.

The housing is nickel coated steel and is extremely strong, at least as good as any conventional deadbolt. What's more, if someone tries to smash it open, a high pitched alarm will start to sound to scare them away.

The whole system runs on four AA batteries (and you do NOT have to reprogram the system when you change them!). There are a few included emergency backup keys to allow you entry access in case of a battery failure. This deadbolt works well on most standard household doors of varying sizes.

It's simple, strong, easy to use and looks amazingly 'stealth' on most houses. It's a high tech and low profile biometric door lock I'd encourage anyone to purchase.

Aegis Optical Biometric Fingerprint Door Lock: Simple solution for a home or business

Aegis means shield or protection, and that's a great way to describe this excellent door handle and deadbolt combination from the company. I recommend this to anyone who is interested in a biometric fingerprint door handle and lock, but who don't want to go 'too techy' and want a device that won't confuse people too much.

This is an excellent product because it offers you some versatility. It lets you choose between using a fingerprint scan, a keypad code, or a traditional mechanical lock and key to gain access to the premises.

The lock system comes with extensive instructions and it's fairly easy to install without a great deal of technical prowess. That said, I'd still opt for a locksmith or contractor to come put it in for you, just in case.

The door handle and lock was designed so that the biometric entry would be the primary means to use the lock. Think of the keypad as a secondary backup, and the mechanical key as a tertiary option only for use in emergencies. The built in flash memory can store up to 100 fingerprint scans. It uses four standard AA batteries, so it's not reliant on the local power grid for energy.

There is a manual deadbolt latch on the inside of the door handle, so when you need to lock it while indoors, you can just flip it without scanning. The whole unit is constructed from reinforced steel and it's very durable.

With gorgeous brushed steel, it looks equally at home in a professional business or home situation. It's a top quality finger print door lock with biometric, keypad and mechanical lock options, so I love the versatility.

Pros and Cons to Fingerprint Deadbolts and Biometric Security

There are a few pros and cons associated with this technology, especially as it applies to use in the home. I'll list them out here:


  • It's cool! If you're a gadget fanatic like myself or just want to wow your friends and family, this is a good way to go.
  • It's a growing technology. Expect to see wider adoption of biometric door locks and fingerprint deadbolts as time goes on.
  • Incredibly secure. The old days of picking or forcing lock cylinders are gone. Thieves could probably smash their way in, but they won't understand where to even begin, and they'll likely move on to easier pickings.
  • A keyless, fingerprint door lock also symbolizes a further security system, whether you have one or not. It's a great deterrent.
  • No more fumbling with keys. Entry is quick and easy, and great if you're carrying groceries or unable to look through your pockets or bag.


  • You can't just give the house key to a friend. You have to program in their individual fingerprint, which takes some pre-planning.
  • Dependent on power. If the batteries go, or if there is a blackout, you'll have to rely on the backup systems (they all have contingencies, however).
  • Certain ethnic groups have lower fingerprint ridges, which can make detection a bit more difficult, but technology in that field is advancing.

Can you buy these type of locks, - in Australia?

DavidG613 on December 23, 2015:

Excellent, informative article. I am a property manager, and I am looking for a biometric lock that cannot be hacked by my tenants, so that only authorized tenants will have access to their apartment. Is there any system that satisfies this criterion? I would be so grateful if you can help me, as I have looked everywhere and cannot find anything.
