UltraLoq U-Bolt Smart Deadbolt

ultraloq u-bolt smart deadbolt

If you want a fingerprint deadbolt for your front door which one should you get? You don’t have a lot of choices when you’re looking for a deadbolt with a fingerprint scanner. Usually you’ll find fingerprint locks with a latch which are not really good as a stand alone front door lock. Ultraloq has a really good fingerprint door lock with the UL3 but it is not something I would recommend for the front door unless you also get a deadbolt. However, I can recommend the Ultraloq U-Bolt Pro Deadbolt for your front door.

Key points of the Ultraloq U-Bolt Pro

  • Deadbolt with a fingerprint scanner
  • Works with Alexa, Google Assistant and IFTTT
  • Works in extreme temperatures – from -22F to 149F
  • Easy installation
  • Up to 1 year or 8,000 uses of battery life
  • Remote Access with the WiFi Bridge

This is a true deadbolt that can either replace your existing deadbolt or go on a new door. This lock can be opened in 6 different ways, but more on that later. And can be used with commands with Alexa and Google Assistant. The lock will also work with IFTTT (If This Then That).

What’s in the Box?

When you open the box you’ll see the brand new lock and the WiFi Bridge. The box comes with everything needed to install the lock. It comes with 4 AA batteries so you can use it right out of the box. And a screwdriver (because if you have cutouts already in your door all you need is a screwdriver to install it).

It has the standard deadbolt parts – exterior lock with keypad, interior mounting plate to attach the interior battery compartment, the deadbolt, 2 backup mechanical keys and has all the screws. And also has some stuff your standard deadbolt doesn’t come with – a user guide, drill template, reset needle and the WiFi Bridge.

The reset needle is used to reset the lock back to factory settings. Used in case you end up losing communication with the smartphone app or can’t remember the codes.

And the WiFi Bridge is used for controlling, accessing and communicating with your lock remotely.

This come with a strike box and strike plate. But I have found that usually your existing strike box and strike plate works just fine for your new deadbolt and doesn’t need to be replaced unless you need a new one. But this would also be a good time to use 3″ screws to attach the strike box to the house studs framing the door opening NOT the door frame.


I have installed many deadbolts and this one is as easy to install as a typical, standard non-electric deadbolt. It installs like most deadbolts – the bolt part first, then the front part with the keypad, then the interior part with the battery compartment.

If you have a slab, or a door without cutouts, then this comes with a template you can use to drill the holes for the lock. Just tape it on the door and use it to perfectly locate the holes on the door for drilling.

With an electronic deadbolt the important thing is to make sure the wire isn’t pinched when tightening the back part on. The good thing is the back mounting plate has a hole for the wire. So you shouldn’t have to worry about pinching the wire.

The Operation

As I mentioned earlier this lock can be opened in 6 different ways.

  1. Fingerprint
  2. Code on keypad
  3. smartphone lock and unlock
  4. auto unlock with geofencing
  5. shake your smartphone to unlock
  6. mechanical key

I have to warn you, once you start using this lock, even if you want to use the code or the smartphone app, you will find yourself using the fingerprint function just because it is so much easier. And you won’t need the key or even your phone to unlock with a fingerprint.


This lock can hold up to 120 fingerprints which is more than enough fingerprints than you will probably need. That is 12 of your friends and family using all 10 fingers or 120 friends and family using one finger. Parents find the fingerprint function very useful for their children because there is no key to get lost or code to forget. My kid kept losing his key so the fingerprint function comes in very handy. And more importantly, your children can’t give friends their fingerprint unlike a key or a code.

I have also found that the fingerprint function is really helpful for memory challenged or elderly folks. They can forget keys or codes but they always have their fingerprints. My mother doesn’t use a smartphone and forgets codes and keys so the opening the lock with a fingerprint is really beneficial and convenient.


The Ultraloq U-Bolt Pro accepts up to 60 user codes. The codes can be 4 to 8 digits long. And it has an anti-peep code input. This lets you put in random numbers then the correct code in the right order and it will unlock. This is becoming more and more commonplace on smart lock keypads but the anti-peep mode keeps onlookers from remembering your code and using it to unlock your door.

Smartphone App

Without the WiFi Bridge the app will work in proximity of the lock with BlueTooth. To protect your lock when using BlueTooth it has two factor authentication. It uses 128 bit AES and a Dynamic Key so it would be very, very difficult for someone to break in using BlueTooth.

The smartphone app works on iOS and Android phones, you can do a lot with it through BlueTooth and does even more if you get the WiFi Bridge. With the app you can check the status of your lock, unlock it and lock it and check the log of when and who opened the lock.

Through the app you can give anytime access to visitors or put them on a timed schedule so if you have a delivery or cable installation or pest control coming you can give access for a few hours on a particular day and after that the code won’t work again.

With the app on your phone you can shake your phone in front of the lock and it will open. Or with the autolock function enabled it will automatically unlock when you get close and lock once the door is shut.

I have found that the unlock feature when you get close is not very good. I think it uses the smartphone’ location ability. So if your smartphone is really good to your location, within 100 feet, then this function might work well for you. But my smartphone sometimes thinks I am in the next subdivision so sometimes the auto unlock wouldn’t work correctly.

Mechanical Key

ultraloq backup key

There is a mechanical key but with all the other ways to open this lock is it needed? Yes, but you’re only going to need it if all the other options to unlock it are not working. Batteries dead, codes forgotten, smartphone app not working or fingerprint reader not recognizing a fingerprint. The front of the lock flips down exposing the keyhole.

ultraloq u-bolt battery backup

Of course the smartphone app will let you know if the batteries are low but in cases where the batteries are completely dead this lock does have a micro-USB port on the bottom. This is for you to plug a backup battery pack up to it and give it temporary power. It does not come with this though. A lot of people have these as a backup for their phone so you probably have one already. It won’t discourage me from recommending this lock, it does have a low battery warning after all.

Ultraloq U-Bolt Pro WiFi Bridge

Buying the WiFi Bridge with this lock will add about $50 to the purchase price but I highly recommend the WiFi Bridge for remote operation. The remote operation is especially useful when you’re away and want to check if the door is locked or grant access to someone. And definitely needed if you operate an AirBnb.

Having the WiFi Bridge also makes it much easier to check the lock status if you’re out of BlueTooth range which is about 40 feet. My front door lock is on the other side of the house from my bedroom, about 100 feet, and I couldn’t check the status from my bed. But with the WiFi Bridge I can check it anytime and from anywhere. So it is really convenient to have that capability.

Do I recommend the Ultraloq U-Bolt Pro?

Yes, I do.

This smart lock is in the same price range as other smart locks. But unlike most of the other smart lock deadbolts this has a very reliable fingerprint scanner.

The warranty is better. The lock comes with a lifetime mechanical warranty and an 18 month electronic warranty. The lifetime mechanical warranty is standard for most smart locks. But the UltraLoq 18 month electronic warranty is better than most lock manufacturers who usually have a 12 month warranty on electronics.

I would like it to have a BHMA grade but couldn’t find one on the box or their website.

UltraLoq’s UL3 lock is a very good lock and the fingerprint scanner on it works very well. This U-Bolt Pro is no different. The fingerprint scanner works very well and there is a lot that can be done through the smartphone app especially if you have the WiFi Bridge.

7 thoughts on “UltraLoq U-Bolt Smart Deadbolt

  1. The ultralock u-pro looks like one of the best and most secure of any deadbolt in the industry because it looks to have the most security and features of any deadbolt. I like the look of it as well and it seems very slick and would deter robbers. Do you think the deadbolt has improved your style of life?

    1. I do know I like the convenience of it and not worrying about my keys. And I also like the ability to check on it when I’m at work and make sure my kids came home safely.

  2. Hi, First I would like to thank you for being a source of such information. I can see that this smart lock can withstand extreme weather condition which is good, I would also like to know how does it behave when there is a Power outage, I am in South Africa sometimes we have load shedding of power supply.

    Thank you in advance for your feedback. 

    1. Good question. So it’s battery powered and if you do have a power outage it will still work. Fingerprint scanner, keypad and smartphone using Bluetooth will still work. The only thing that won’t work is remote operation because that needs wifi and the wifi won’t work during power outage. Hope that helps!

  3. This seems like a really good measure for home security. I’m particularly intrigued by the fingerprint feature. Like you said, it automatically eliminates the unwanted situation of loosing a key or forgetting your password. This is something I have experienced firsthand, so I understand how helpful this innovation is to me.

    This has been really helpful. 

  4. I have some experience with an electronic lock at my friends place before, but his is not advanced in anyway as this one that I am feasting my eyes on right now 🤤.. Like e Oh my God! 😲.. Shaking phone to unlock.!?! 🔓 😱.. That’s crazy man..
    My Dad would certainly wanna get this at home for sure.. Thanks 💙

  5. Thank you so much for the awesome review! I love this lock honestly.  It’s very modern and amazing. I like how it has so many  fingerprint stamps so that kids can use it since I have kids.  The addition of the app is pretty great too because it allows access to people from the comfort of your phone!
