U-tec Ultraloq Bolt Fingerprint Matter review: Now hear this?

At CES 2025, U-tec launched its first lock with Matter, the latest installment in an ongoing refresh of the U-Bolt Pro, which we reviewed over four years ago. Now called the Ultraloq Bolt Fingerprint Matter (dropping the “U-” for this line), the big update is Matter over Thread support, along with a few behind-the-scenes enhancements.

Besides the Bluetooth and Thread-only Bolt Fingerprint Matter lock that we’re reviewing here, there’s a forthcoming variation that works with Wi-Fi as well as Thread. This point bears repeating: the Bolt Fingerprint Matter we’re looking at now does not have integrated Wi-Fi, and can only communicate with Wi-Fi networks if you purchase the Ultraloq Bridge Wi-Fi Adaptor ($50), which we did not receive for review. Of course, with Matter’s Thread connectivity, you may not need access to Wi-Fi at all.

Those unconcerned by the Bolt Fingerprint Matter’s lack of Wi-Fi may yet be perturbed by another issue: the unit’s noisy motor. More on that in a bit.

Design

The Ultraloq Bolt Fingerprint Matter lock arrives alongside other new Ultraloq models, including the standard Bolt Fingerprint, a non-Matter version of the lock that works with Alexa, Google Home, and Samsung SmartThings (a separate Bolt Fingerprint SKU works with Apple Home, too); the Bolt NFC Wi-Fi, an Apple Home-compatible lock that can unlock itself when you hold your iPhone or Apple Watch near the unit; and the upcoming Bolt Mission UWB+NFC, which will work with ultra-wideband networks.

The physical design of the Ultraloq Bolt Fingerprint Matter remains about the same as U-tec’s earlier smart locks, and just as divisive: Either you are going to love the squat, all-black exterior escutcheon (just 3 x 3 inches in size), with its 10 physical numeral buttons ringing a physical keyhole and a fingerprint reader, or you’re going to hate it.

At best, it looks like something that would work best protecting a closet at the airport, and it remains something I would not really relish having on the entrance to my house.

Installation

U-tec proudly says that the Bolt Fingerprint Matter Edition can be installed by attaching just four bolts, and that bears out: Two bolts connect the exterior escutcheon to an interior frame through the door, and two more bolts mount the interior escutcheon onto that frame.

Although the screws on the interior escutcheon are set within very narrow channels that weren’t quite wide enough for my usual screwdriver to easily access, the physical installation proceeded with zero trouble. That’s a big shift from our experience in 2019, as U-tec has fortunately discontinued the need to trim the tailpiece of the lock with a hacksaw and has corrected a few other horribly misguided design mistakes.

The lock carries an IP65 weather resistance designation (meaning it should be dust-tight and resistant to water jets from any direction), and U-tec says the lock meets ANSI level 1 standards, though it is not actually certified as such. Power comes courtesy of 8 included AA batteries, which Ultraloq says will last for about a year of typical use. There’s no emergency power port, so make sure you keep one of the included physical keys handy.

Setup and Matter configuration

Most users won’t need a manual to install the lock, and that’s good, because U-tec doesn’t supply one in the box. An included card rather has a QR code printed on it which promises access to a User Guide, but this in fact takes you to U-tec’s support site, specifically a page featuring various videos for unrelated products. If you came to this review looking for the manual, I dug it up on this page.

Once installed, electronic setup can be done through the U-tec app or through the Matter platform of your choice. However, U-tec notes that numerous features are available only if you’re using the “U home” platform, including the ability to create temporary access codes, add fingerprints, and the geofencing auto unlocking feature. I tested the lock with both the U home system and via a Matter connection to iOS and the Home app. (I would recommend only configuring the lock with one platform, as various settings can become contradictory if you have both configured simultaneously.)

Christopher Null/Foundry

My first attempt to connect to the lock via the U home app failed. The app simply couldn’t find the lock, though the Matter connection worked fine. I ended up resetting the lock twice, which eventually got things working well enough for U home to find the lock (though this also forced me to re-create the Matter connection).

App control and functionality

The U home app isn’t complicated, and helpfully it even automatically calibrates the lock opening direction during the setup process. U home’s authentication system is built around creating users (up to 50), each with configurable access via app, 4- to 8-digit PIN (1 per user), or fingerprint (2 per user). Users can be set as Admin (full control, in addition to the ability to add additional users), Normal User (full-time access via app, PIN, or print), or Temporary User (limited by time/date/day of week, or restricted to opening the lock a finite number of uses). When PINs are entered, the lock supports the addition of extra digits before and/or after the PIN as part of an obfuscation strategy against snoops.

Additional lock features are scant, but they include auto-locking (configurable for 10 seconds to 30 minutes) and a geofencing auto-unlock mode, which works better than most. An included magnetic door sensor (the use of which is optional) can inform the lock whether the door is ajar (and prevent auto-locking if it is). Logging is robust and includes both lock and unlock actions, though note that Matter-initiated actions are tagged as “Z-Wave Unlocked” in the log.

The physical access features of the lock work well. U-tec has always had great fingerprint reading technology, and this lock continues that streak, even though the location of the reader makes it a little difficult to access. I didn’t have any trouble opening the lock via print or any of the other approved means, although I found the Matter connection often to be slightly slower, taking a couple of extra seconds to open or close the lock.

Noise (too much of it, that is)

I did have one major complaint, however: The lock has a grinding, wheezing motor, which is loud and alarming and simply unacceptable for home use.

Whether locking or unlocking, the Bolt sounded something like a dying animal, which did not instill confidence and made it a non-starter in my house.

Should you buy the U-tec Ultraloq Bolt Fingerprint Matter?

Kudos to U-tec for getting Matter up and running on its lock, but in 2025, a lock like this should have Wi-Fi built in, without the need for a separate bridge. (Again, a Wi-Fi-enabled version of the Bolt Fingerprint Matter is on the way.)

My bigger concern remains the amount of disconcerting noise this lock produces–which is more disturbing the more you use it–and which raises questions, for me at least, about the potential longevity of the system.
