I can confidently say the Utec Bolt smart lock is one of the best I’ve had the pleasure to use, bar none. Usually, I hesitate to say things like that. Especially if I haven’t used a lot of different devices. But I have gone through a few smart locks on my front door, including Schlage models like the Camelot. Utec Bolt works well, it’s incredibly reliable, interactions are speedy — so you’re not left standing there at the front door waiting. Plus, the fingerprint scanner works damn good provided you’ve programmed it correctly beforehand.

It uses wireless connectivity

I will follow that up with the point that this is a radio-wireless frequency lock. So, if you have an aversion to using smart locks like this on your home, you’ll want to avoid it. I understand the sentiment of not wanting to use anything wireless on a physical lock besides a keypad. I get it. In choosing to upgrade for that added convenience, like unlocking with a fingerprint, or your phone, you can open your home up to vulnerabilities such as wireless hacking. But I also have other physical defenses on my front door like an extra deadbolt or chain. I won’t say exactly which, a man has to have some privacy. That said, this smart lock isn’t the only defense for my main point of entry.

I also don’t really see hackers breaching my home and smart lock, specifically. There are hundreds of other homes in the neighborhood. I don’t live in a rich, gated community surrounded by well-off people, but I suppose stranger things have happened. Thieves could also come in through a window or other entry points.

As for why this Utec Bolt Fingerprint smart lock is so great, we’ll have to delve into the particulars, cover what it does and doesn’t do well, and, per usual, finish the ever-loving review here at Techigar. Let’s fucking go.

What is the Ultraloq Utec Bolt Fingerprint Matter smart lock?

Utec Bolt is a smart lock that replaces the primary deadbolt on your door, front, side, wherever you want to install it. You will need a compatible deadbolt, but that’s pretty common on most doors built this century. You remove whatever deadbolt you have installed and swap it out for this and all the hardware is included, even the frame that goes on the side of the door. So, if you break anything while uninstalling your old lock you’re covered.

What makes the Utec Bolt unique is the sheer variety on offer in regards to accessing your door. You can unlock the door with a code, using the built-in keypad, whether permanent or temporary — you can issue temp keys to neighbors, friends, and family, for instance. You can also use your fingerprint if you have programmed that. Or, you could use the mobile app, an NFC-enabled device, or, as a last resort, physical keys. It does come with a set of matching physical keys and there’s a physical lock slot right in the middle.

It also works with and is compatible with Apple Home, Alexa, Google Home, Samsung SmartThings, IFTTT, and there is a Matter (over Thread and Bluetooth) model, as well. The model I have is Matter-enabled.

Installing the lock is pretty intuitive and simple, I’ve done it before several times so I was no stranger to the process. But even if I had never installed a smart lock before I feel as if the process would still be pretty straightforward. If not, there are detailed instructions packaged with the lock and the mobile app will walk you through the process, as well. The most difficult part is removing your old deadbolt and the lock fixtures and making sure everything lines up correctly with the new lock.

What does it do differently?

It’s a smart lock, so in principle, it’s really no different than any other smart lock. The idea is to give you more opportunities to interact with and unlock your door. You can use a mobile app, keys, codes, fingerprints, you name it. The latter is really the big feature here, the option to program and open the lock with your fingerprint. 

But it’s also compatible with a huge selection of additional platforms and protocols, like Matter. Which means, if you want to, you can set it up so that it’s not interacting with the cloud. Matter-over-Thread allows you to still use compatible devices over a local network, even when the internet is down. To set that up you also need a Matter-over-Thread hub controller. That could include devices like actual hubs, like the SmartThings Hub, smart speakers like Amazon Echo speakers, smart TVs if compatible, and other small devices.

128-bit AES data encryption protects codes, passwords, and information — or data really — used by the lock and related apps. You can store up to 100 fingerprints, two per user, but that threshold is a bit wild to be honest. I created fingerprint profiles for everyone in my family. It works amazing, though I will add it’s very difficult getting younger users programmed in there. Both my son and daughter’s fingerprints took a long while and a lot of tries to get right. However, they are both under 10 and have small fingers.

Auto Lock and auto unlock are super convenient

When you install the lock on your door you also place a small magnetic sensor nearby. This sensor allows the system to detect when the lock is engaged or disengaged. That also empowers some auto lock and unlock functions. For example, when I step outside to check the mail, if I get distracted by a neighbor or take a walk, the lock will auto lock after the interval I’ve set, which is five minutes. You can adjust this to what you want — from 10 seconds up to 30 minutes. A separate auto unlock will automatically disengage the lock when it detects my phone within proximity.

Why does this matter? Well, it’s simple, if you forget to lock your door it locks for you. If your hands are full and you have your phone the lock will auto disengage if you have that feature enabled. You don’t realize just how pragmatic these features are until you start using them. There are many times that I have walked out my front door, got distracted and would have left my home unlocked. It’s not a huge deal if you live in a safe neighborhood, but these days, you never can take your security too seriously. I appreciate these features and they work well.

What about battery life?

The lock takes eight AA batteries but you probably don’t want to use regular alkaline batteries. Don’t worry, it comes bundled with that many to start. You can install it and get it working right away. I would say that’s probably the biggest caveat of this lock is how many batteries you need. Eight is a full pack of Lithium disposables pretty much. But the good news is that the battery life is quite good. It’s very efficient at consuming energy, even better if you use Matter-over-Thread so those last for quite a while — up to 8 months at least with Wi-Fi active, over a year with Matter. During the review period I did not have to change the batteries at all. The battery life is still reported as full or “high” in the app. 

But I do know how to do that. You simply take off the front face of the lock, pop the old batteries out and put the new ones in. It’s easy.

The Xthings mobile app experience

Ultraloq is owned and managed by Xthings. So, the mobile app you use to set up and interact with the Utec Bolt is the Xthings Smart Home app on iOS or Android. One of my biggest gripes with smart home devices is that if you don’t buy things within the same ecosystem you have to manage them all through separate apps. It’s an absolute pain in the ass and it’s one of the downfalls of modern smart home tech. Currently, I don’t own any Ulticam devices or any Utec equipment so the Xthings home app was exclusively for this smart lock.

I can’t speak to the iPhone or iOS experience, but the app on Android is really snappy, responsive, and designed well. I have a Samsung Galaxy S25 Ultra so make of that what you will. Something to note, however, is that once the lock is installed you don’t have to do much within the app. You can leave your phone inside and engage the lock with the codes, biometrics or even physical keys. You only have to use the app to set it up, update firmware, add users, and so on.

On the main page of the app there is a small footer ad for Ulticam security products. It’s not intrusive but it is there if you hate ads, period. When you open the side menu, you’ll also see items for existing Xthings products and experiences such as “Works With,” or “Store.” There are support and community options, as well. It opens right to the main page with devices you have set up. In my case, that was my smart lock.

What’s the experience like?

It’s easy to set up new users, and I configured profiles for everyone in my family right away. You can also adjust some of the more basic settings quickly. There’s really not too much here that you wouldn’t be surprised to find. You can designate the room or install location, enable or disable notifications, adjust the auto lock, check battery life, update the firmware and so on.

One neat feature I discovered, and haven’t seen in similar apps, is an option to transfer the device to a new owner. Say I were to replace my lock and upgrade, give away or sell the Ultraloq Utech Bolt I could simply transfer ownership via email within the app. That would allow the new recipient to register the device using the original serial number which is pretty handy. No idea what transfers over, they may not benefit from a warranty, but they can set up the app and use the lock like new.

There is also an instant Lockout mode, maybe for emergencies. But it disables all electronic unlocking methods at once, including fingerprint, codes, app and integrated controls. With that on you can only unlock it physically with keys or from the inside. It’s accessible from a quick toggle within the app settings.

What’s the verdict, and the price?

I love this smart lock. The battery life is fantastic, though it does take a lot of batteries. The features are great and, in my opinion, it truly makes for a “smart” lock and justifies the upgrade over a dumb deadbolt. The app is well-designed, and even if some of the niche elements are not the greatest — in-app ads — it puts your most used devices front and center and makes everything simple and convenient. The fingerprint scanner works really damn well, and I’m impressed, even if it struggles to recognize little children’s prints. It’s fast, gets me into my house quickly, and I don’t have to worry about carrying my phone or other devices. You can always unlock the device with a code or physical key, too.

Security wise, data is encrypted, I never really felt like I wasn’t in full control and you have the freedom to add or remove users as you wish. There are no “you added too many people you must pay” restrictions at least from what I can tell. Moreover, you can revoke access at any time if you, say, give a code to a temp user like a nanny, dogwalker, housekeeper, or whatever. It’s also really simple to use. My kids love it. They use their fingerprints when they can, their codes otherwise, and, if nothing else, it entertains them for a minute or two.

Final thoughts and price

I’m overly fond of the Matter-over-Thread support, especially when the internet goes down. My house is set up for Matter, though, so keep that in mind. There are no subscriptions to worry about, no cloud services forced down your throat, and the lock just works. These days, I think that’s a huge boon in the smart home world.

The Ultraloq Utec Bolt Fingerprint model is $200 at full price for either the Apple Home + Wi-Fi + Bluetooth variant or the Matter over Thread + Bluetooth variant. It looks like you choose one over the other, but the Matter version supports both Apple Home and Matter, so if you know you want Matter-over-Thread go with that one. Prices may vary for different bundles. For example, one that includes the lock and a handle is $250 at full price, versus $200. Altogether, I’d say it’s worth the cost and worth the upgrade.

There is another model with no fingerprint scanner that allows for NFC unlocking (tap to unlock).
