CSA certification record for the ULTRALOQ Fingerprint Door Lock (CSA2610SMAT50732-24)

The CSA's ULTRALOQ Fingerprint Door Lock page identifies the product by Family SKU UUL-Bolt-Pro and Family Variant SKU Bolt-F. It carries certificate ID CSA2610SMAT50732-24, certified 20 February 2026, with firmware version 01.55.0066 and hardware version 1.2. Vendor ID is 0x147F and Product ID is 0x0013. The page lists Matter specification version 1.4, Thread and Bluetooth transport, and primary device type ID 0x000A, which is the Matter door lock device type.

The same CSA page shows four additional Xthings ULTRALOQ Matter records: ULTRALOQ NFC Door Lock certificate CSA2610TMAT50733-24, ULTRALOQ Smart Door Lock certificate CSA2610UMAT50734-24, ULTRALOQ Bolt Pro Smart Door Lock certificate CSA2610QMAT50730-24, and another ULTRALOQ Smart Door Lock certificate CSA2610RMAT50731-24. These are listed under "More by Xthings Inc." on that page. To verify a specific SKU, use how to check Matter certification or browse MatterCheck's SKU list.

Bolt Fingerprint Matter over Thread + Bluetooth vs Apple Home + Wi-Fi + Bluetooth editions

U-tec's Bolt Fingerprint product page lists three technology and color choices: Apple Home + WiFi + Bluetooth in Black & Satin Nickel, Apple Home + WiFi + Bluetooth in Black, and Matter over Thread + Bluetooth in Black & Satin Nickel. Only the Matter over Thread + Bluetooth variant is a Matter device; the Apple Home + Wi-Fi + Bluetooth variants use Apple Home over Wi-Fi and Bluetooth. The page states that "Apple Home and Matter work with select ULTRALOQ models" and that the Matter edition requires a Matter Over Thread hub controller, also called a Thread border router.

U-tec lists the Bolt Fingerprint at $199.99. At the 28 October 2026 fetch, both the Apple Home + Wi-Fi + Bluetooth and Matter over Thread + Bluetooth variants showed "sold out or unavailable" in the product variant selector. That can change, so check the U-tec product page before ordering.

Controllers ULTRALOQ lists for Apple Home, Google Home, Alexa, SmartThings, and Home Assistant Thread border routing

ULTRALOQ's Works with Matter page states that to connect a Matter over Thread device, you only need a Thread-enabled Matter Controller of the desired ecosystem. It also says Matter setup begins with scanning a QR code. For background on why Thread needs a border router, see Matter hubs and Thread border routers and Thread vs Wi-Fi for Matter devices.

Apple Home controllers listed by ULTRALOQ

The Works with Matter page names Apple TV 4K (3rd generation) Wi-Fi + Ethernet, Apple TV 4K (2nd generation), HomePod (2nd generation), and HomePod mini as Thread-enabled Matter controllers for Apple Home. See Matter support in Apple Home.

Google Home controllers listed by ULTRALOQ

The page names Nest Hub (2nd gen), Nest Hub Max, Nest Wifi Pro (Wi-Fi 6E), and Google TV Streamer (4K) as Thread-enabled Matter controllers for Google Home. See Matter support in Google Home.

Amazon Alexa controllers listed by ULTRALOQ

ULTRALOQ's list includes Echo (2nd Gen and newer), Echo Dot (2nd Gen and newer), Echo Dot with Clock (2nd Gen and newer), and Echo Flex. See Matter support in Alexa.

SmartThings controllers listed by ULTRALOQ

The list includes Aeotec SmartThings Smart Home Hub, Samsung SmartThings Station, Samsung SmartThings Hub Dongle, and Samsung SmartThings Hub v3. See Matter support in SmartThings.

Home Assistant controller listed by ULTRALOQ

ULTRALOQ names Nabu Casa Home Assistant Yellow as a Thread-enabled Matter controller for Home Assistant. See Matter support in Home Assistant.

Google Home setup path: Add Device, QR code, and the IPv6/Thread requirements

Google's Matter setup guide says you need a Google Account, IPv6 enabled on the home Wi-Fi router, a Matter-enabled hub for Google Home, and for Thread devices, a Thread border router. The phone or tablet must run Android 8.1 or later with Google Play services version 22.48.14 or later, or iPhone/iPad with iOS 16.5 or later, and support Bluetooth Low Energy 4.2 or higher.

In the Google Home app, tap Add Device at the top right, then Scan QR code. If the code cannot be scanned, tap Add a different way, enter the device brand, and select ULTRALOQ. Google also says that if the lock was first set up in the U-tec/Xthings Home app, the manufacturer app may show a prompt to share the device with Google Home. Once paired, you can share to a second platform with Matter multi-admin; see sharing a Matter device to a second platform.

Matter door lock capabilities vs the Xthings Home app for Bolt Fingerprint

The CSA ULTRALOQ Fingerprint Door Lock page describes unlocking via fingerprint, keypad code, app, voice control through the ecosystem, and mechanical key. U-tec's Bolt Fingerprint page lists Phone App, Watch App, Fingerprint, Pin Code, Auto Unlock/Lock, and Physical Key among its access methods. The Matter door lock device type itself exposes lock/unlock state and lock/unlock commands; fingerprint enrollment, PIN user management, and cloud remote features stay in the U-tec/Xthings Home app rather than moving through Matter.

ULTRALOQ's Works with Matter page includes an integration matrix with rows for Lock/Unlock by app, Voice Control, Remote Control, Notifications, Scenes & Automation, Temporary Code, Add fingerprints by app, and Auto Unlock, plus a note that features will be updated as the Matter protocol matures. The same page says Xthings Home remote control requires a U-tec Wi-Fi Adaptor; otherwise, a third-party hub is needed. For general capabilities of Matter locks across platforms, see Matter smart lock support.

Bolt Fingerprint battery, hardware, and door fit numbers from U-tec's specifications

U-tec's Bolt Fingerprint product page says the lock uses 8 AA alkaline batteries. It lists up to 1 year of battery life with Matter over Thread and alkaline batteries, and up to 1.5 years with Matter over Thread and lithium batteries. The CSA page also says the lock is powered by 8 AA batteries. The exterior assembly is IP65 rated with a working temperature of -4°F to 149°F (-20°C to 65°C); the interior assembly is 14°F to 131°F (-10°C to 55°C).

U-tec says the lock fits a US standard door with a 2-1/8 inch (54 mm) diameter face hole and a 1 inch (25 mm) diameter latch hole, for door thickness 1 3/8" to 1 3/4" (35-45 mm), with an adjustable backset of 2-3/8" or 2-3/4". A thick door kit is needed for doors between 45 mm and 57 mm. Installation requires no wiring or drilling, according to U-tec.

If pairing fails: Google's freeze checklist and the Matter variant check

First verify you are using the Matter over Thread + Bluetooth variant, not the Apple Home + Wi-Fi + Bluetooth variant, because only the Matter variant will pair as a Matter device. U-tec's product page labels these variants separately. Next, check that a Thread border router is powered on and in range, and that the setup code is correct. For codes, see recovering a lost Matter setup code.

Google's troubleshooting section says if setup freezes or does not finish, restart the Matter device, close the Google Home app, clear the Google Home app cache, restart the phone, and try again. If setup still fails, Google says a factory reset of the Matter device may be needed. The U-tec product page includes a customer review from T Todd that states: "Wi-fi is finicky. Pairing is harder than it should be (one lock still hasn't paired)." See what to do when a Matter device won't pair.
