This is not a lock for a front door.

The problem with using a fingerprint door lock for your front door is finding one with a deadbolt. Biometric front door locks or on any other exterior door should have a deadbolt.

I have seen many “best” biometric or fingerprint door lock reviews but none of them address this problem or situation. Almost all of the ones that are reviewed have a latch like the one pictured and not a deadbolt.

There are many fingerprint or biometric door locks that look and work nicely however, most of them have a latch with a handle and are more suited for a storage, office or some other type of interior door.

Most people have a handle and a deadbolt on their front door. Most importantly, the deadbolt is there for security considerations. While the handle has the latch that will disengage when the handle is turned.

If you’re going to use one of these fingerprint door locks that only has the latch on your front door you will also need a separate deadbolt. And that sort of defeats the purpose, no?

Benefits of a Fingerprint Door Lock

The biggest benefit of opening your door with a fingerprint or biometric front door locks is not having a key or to remember a code.

Most smart locks require a code that is 4 digits, some go to 8 or 12 digits. Not surprisingly, 8 digits is a lot to remember for some of us. Or they require use of a smartphone with the app that needs to have BlueTooth that you can unlock the door with.

The elderly populations of just about every country are increasing. And, unfortunately, as people age they get more forgetful. They are also less interested in new technology like wanting to use or learning to use a smartphone.

But, they are still capable of putting their finger on the scanner. A biometric front door lock doesn’t require a key or code to unlock the door.

For example, this has been an experience in my own life. Even with the best of intentions, like using a birth date that you would think will be easily memorable, it is forgotten or jumbled and not remembered correctly. Or get them a smartphone that is never used and therefore never on their person.

Fortunately, this is easily avoided with biometric front door locks. Because there is nothing to remember but putting your finger on the scanner.

Also, children and those with special needs could benefit from fingerprint home door locks as well.

No more keys being made

Children, especially my child, would have benefited greatly with a front door lock like this. He must have lost a key at least every semester.

It got to the point where I had extra keys on my keychain. So that when I asked him where his key was and he said he didn’t know, I could give him another. We ended up with a simple electronic lock with a code.

Final Thoughts on Fingerprint Door Locks

Unfortunately, at the time of this writing there are only 4 quality deadbolts that have the option to be opened with fingerprints.

Fingerprint door locks are very helpful – no need for keys or to remember codes or even carry a phone or deal with an app. Moreover, if you’re putting it on the front door it really needs to be a deadbolt and not just a latch.

The recommendation from me is the first one on this list – from Lockly. They have the best track record, better reviews, it can be used remotely with the WiFi hub and has a better warranty in case of problems with the lock.

And you should take a look at this smart lock buying guide for help deciding or knowing which smart lock will work for you.

Since we’ve moved into our new home, I have been quite bothered about how to tighten the security a bit, likewise my husband, this is a good eyes opener for us. I think biometric front door locks are durable and more secured than using keys that can be duplicated, or can get lost at any time. Lockly Fingerprint Keyless Door Lock is the best I could find, I’ll discuss it with my husband and get back to it.

    Bill Kiser · December 12, 2019 at 11:10 am

    That is one of the benefits of a fingerprint door lock, no keys needed and easy to unlock quickly with just your finger.

Hey, 

I haven’t installed bio metric front lock yet. I got very useful information from your post and we have many types of lock available. My house work is on progress. Now I am thinking about bio metric lock. It looks nice as well as we don’t need any key to open it. 

Thanks for giving such a wonderful information.

Its a great opportunity for me to have come across this article because it is just what I need right now and it came at the right time. Using biometric door lock is of great benefits mainly that you don’t need to go around with key, you fingerprint is always with you, so it’s easy to access. I’ve seen about two that are need to look into properly, I’ll delibrate on which one I like most.

I have been looking for a great deadbolt lock using technology like this.  I have kids that walk home from school everyday and this would be very helpful for them to get into the house fast yet not have to carry any keys.  I do have one question on them and that would be it says that they will fit most doors but do you think you will have to do any drilling to the door as you install?  I don’t have any way to do this so would have to hire someone to do this.  They are such a cool idea and would think they would be very helpful for a large family also as you can save a lot of finger scans.  Does the door lock let you know if the batteries are low with an alarm?  Ok well thank you for the great info and I have saved the site so I can find some more great ideas from your site.

    Thanks for visiting Douglas. Some of them do require an additional hole to be drilled through the door, like the Wandwoo model. This is because the height of the outside component, with the keypad and fingerprint, makes the lock top heavy. The SCYAN and Lockly models do not require this additional hole. They all hold at least 99 fingerprints, some hold 100. And they do have a low battery warning, either on the lock itself or through their respective app. But if the battery does run out they all have contacts on the bottom that you can use a 9 volt to “jumpstart” the lock, lets you get in and replace the batteries.

      Douglas · December 13, 2019 at 9:20 am

      Awesome thank you for all the info searching further for the best one for my situation. Thank you for getting back to me about all the questions also.

        Of course. Glad to help!

Great revelation, I have always heard of this biometric locks but never knew how it works, I sometimes think about implementing one but due to lack of adequate information I just let it go, I believe the biometric fingerprint print door is the most same and easy lock to have, one thing the key is always with you, that’s the finger print, the worries could maybe: what if I get some injuries on my finger that erases the usual finger print, ?? How easy is it to change the finger prints?. Can the lock save several finger prints??. Thanks for sharing such a wonderful article.

    Bill Kiser · December 13, 2019 at 12:33 am

    These locks all save 99 or 100 fingerprints so you can have a “backup finger” I suppose. But they all also allow you to use a code to get in so if the fingerprint doesn’t work you can use the code. Changing the fingerprint is easy but with being able to program 100 fingerprints it probably won’t be necessary unless it used as lock at a business.

Hello, I really appreciate your time and effort on writing about these biometric front door locks which are something that I’ve been looking for. The way you laid it out is perfect and informative, I agree that the biggest benefit of these locks is not having to carry a key or remember a password, you’re not going to lose your fingerprint so you’ll never get locked out. About the Wandwoo, you said it can be opened with a physical key but unlike the other ones I don’t see a key hole for that, where would the key be inserted? The big circle with the little dot in the center, is that it?

    Bill Kiser · December 13, 2019 at 12:39 am

    Right, so the keyhole is behind that circle with the little dot. That circle is a cover over the keyhole and it rotates out of the way so if you need to you can put the key in.

Thanks for explaining why it is good to make use of biometric lock and also the best ones in the market, I like ZKTeco Fingerprint Smart Lock, I’ll look into getting for my house.

The lockley biometric front door lock looks great to me. It’s wonderful that these locks are now available. I had only seen them in movies, lol. I need to get better informed about new technologies 😉 

Do these locks work on batteries only or also on electricity? I am building a house, and now you’ve given me a great new idea, getting a biometric lock installed. While I’m certainly able to remember a code and I am careful with my keys (I always leave them in the same spot to avoid losing or misplacing them) ;-), I hate carrying around a lot of keys. I prefer key rings with a minimal amount of keys, I find it annoying to waste time looking for keys. So the biometric lock seems like the perfect solution 🙂 I am going to check out the lockley, is it reasonably priced?

    Bill Kiser · September 13, 2019 at 10:49 pm

    I am like you, I always put my keys in the same place because then when I’m looking for them they’re always there. My wife and kids are a different matter 🙂

    But the Lockly runs on batteries so even in a power outage you can still get in. 

    And it is in the same price range as other smart locks that don’t have fingerprint technology – about $250.

Dr. Baker · September 13, 2019 at 8:20 pm

I am SO glad that I just ran across this article. Literally last week I told my husband that I wanted a fingerprint lock for our front door. We went to the store and viewed some, but they would not work with a deadbolt! Timing is everything and I ran across this post at the perfect time. I am definitely most interested in the ZKTeco Fingerprint Smart Lock that you have on your site. I like that it has the lock out feature as well as everything else that it offers. I am going to discuss this when my husband gets home and hopefully make the purchase tonight! Thank you again! I’ll let you know how it goes!
