Good lock, but unreliable Remote capabilities (Wi-Fi disconnects)
I bought two of these locks for my home, installed both, one for the front of the house and one for the back. Easy to install, worked well initially, but started running into trouble not too long after with the remote capabilities due to constant disconnecting of the devices from Wi-Fi despite having good signal and within range of my U6 (Ubiquiti) Pro AP. Both were initially connected to a SSID which supports 5/2.4GHz, and given their device specifications state this does not work with 5GHz, I created a dedicated 2.4GHz SSID specifically for these devices. Even after doing so, the disconnects have still persisted. I noticed a firmware update (01.42.0024) was available and updated both devices (also a headache as this requires Wi-Fi and the constant disconnects made this a challenge as well) but still the issues have persisted. I have a number of other devices on these APs with no issues and these are Enterprise grade Wi-Fi systems so this should not be an issue. Despite these challenges, the locks themselves work well, the biometric and multi-user setup is nice and these continue to work once setup even without Wi-Fi otherwise I would swear this off. It is hard for me to provide a more positive score than a 3 currently, but hopefully they are able to fix the Wi-Fi issues which would significantly increase the products evaluation. I have seen a number of complaints on their site from other customers going past over a year so maybe I should not be optimistic for a resolution to these issues, but if you are not in desperate need of the remote unlock feature, the other mechanisms for unlock work well. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ **UPDATED REVIEW** I am writing an updated review based on my interaction with the Support team at ULTRALOQ. Ultimately the issue of the locks dropping connectivity stemmed from an ISP issue which would some times drop active valid connections which, unfortunately in ULTRALOQ's case, would result in the product likely believing something was wrong and disconnecting/reconnecting. As to why this is the case, the support team hopefully is looking into this as such an issue should not make a device drop from a local AP, but non-the-less, these connectivity issues have ceased since I have worked to resolve this with my ISP. Other than this, the only issue I still encounter is trouble updating firmware when they become available. I hope the team will work to ensure that process is easier and more reliable, but that issue is no where near as critical as the prior mentioned above. Since then, both locks have been working well.

Easy to install and convenient to use
We’ve been wanting a keyless entry for a while and decided to take the plunge with this ubolt deadbolt. It took a few minutes longer to install because we had to chisel out around the door (our builder apparently took a shortcut when installing the original lock). But it was easy. The app and adding the users were fast and easy, I just opened the app and scanned the q-code and voila! I like that everyone has their own passcode and fingerprint because the app keeps a log of who and when people are going in and out. You can set it for occasional users like cleaning people or deliveries or single use codes, very cool! It auto-locks too so if your hands are full and you forget to lock it … no problem it locks itself. We have had no issues with it unlocking by itself or malfunctioning and locking us out but this lock also has a backup key for emergencies which I really liked. Other brands have a usb or charger plug for emergencies but it’s not like I carry one of those around when I’m outside my house so it didn’t seem practical. I would like to replace my other door locks with these too just waiting for a sale.

Good product that still can be improved
This is my 11th Ultraloq (6 in rentals, 2 in past home, 2 in present home). I mostly like the way they function and their customer support. Connectivity is important to me to remotely mange the rentals. For my homes I've bought fingerprint models with little success. Fingerprint works when I set it up but rarely after that. Licking and wiping my finger (yuck) sometimes helps. I'll keep fiddling with the two I just bought. Especially early on I had a lot of issues that were resolved by replacing the keypad or occasionally the main component. I rekey the locks so use the same key for multiple doors and to have a master key for all my rentals. The lock smith charges extra because the lock cylinder isn't great and is hard to work on. One lock came with an incompatible which cylinder u-tech support replaced with a compatible one. What I would like to see: It's impossible to see if the lock is locked or unlocked from across the room. Making the part of the knob you grab white would fix this at no cost (I paint them). Batteries are the biggest issue, I refuse to just keep throwing them out. Despite U-tech's insistence that rechargeable don't work, they do. I leave a charger with batteries at the rentals and tell the tenants to replace them when needed. I would love to have an option to hardwire power (preferably POE). For me the point is to not give out keys that need to be rekeyed for each new tenant. Maybe hardwire to the frame with contacts to power the part on the door. Finally I'm automating at home with Home Assistant (way too many individual apps). Please provide an API ! If I have to have batteries the best setup would be a low power model that uses z-wave and can be controlled by home assistant. Executive summary: Rechargeable batteries!, fix fingerprint, home assistant API, contrasting color on knob so you can easily see if door is locked and a hardwired (POE) model.

Broken out of the box
Installed easily. Connected to the App easily. Control via the app takes 3-10s, mostly more than 5s to lock / unlock and that's with an access point within 5ft. Better to use a key. It seems it disconnects from the wifi when inactive, then connects, and allows interaction. I tried via HomeKit and it was even worse and >50% of the time it was unresponsive. The keypad and fingerprint scanner are DOA - the keypad lights up but pushing buttons does nothing and the fingerprint will not learn. Fortunately the mechanical key worked. Also, once you uninstall the app fails to delete my account when asked. This thing is buggy. Better to stick with a known brand such as Schlage. I have one of their locks on another door and it's flawless.

The Ultraloq smart lock has exceeded my expectations. The fingerprint scanner is outstanding. It’s fast, accurate, and reliable, making entry effortless without ever having to reach for keys. Installation was quick and straightforward, with clear instructions that made setup simple. The lock feels solid and well built, adding both convenience and peace of mind to my home security. I also appreciate the variety of ways to access the lock; fingerprint, code, smartphone app, or traditional key, as each method works seamlessly. The Auto Lock feature is another highlight, ensuring the door always secures itself after I come inside, which provides tremendous reassurance. Overall, this smart lock combines modern security with unmatched convenience. I highly recommend it to anyone looking for a dependable and feature-rich upgrade to their home.

I’ve been using the Ultraloq Bolt Smart Lock for about two months now, and I can confidently say—it’s one of the best smart home upgrades I’ve ever made. From installation to daily use, this lock has exceeded my expectations in every way. Installation & Setup: Surprisingly Simple The instructions were clear and easy to follow, even for someone like me who’s not particularly handy. It fit perfectly into my existing deadbolt cutout, and I didn’t need to drill or modify anything. The app setup was seamless—Bluetooth pairing was quick, and firmware updates were automatic. Smart Features That Actually Work Remote Access: I can lock/unlock the door from anywhere using the app. It’s perfect for letting in friends when I’m not home. Auto-Lock & Unlock: The geofencing feature is brilliant. It unlocks as I approach and locks automatically when I leave—no more fumbling for keys! Voice Control: Works flawlessly with Alexa. I can check lock status or control it with simple voice commands. Activity Log: I love being able to see who’s accessed the door and when. It adds a layer of security and peace of mind. Security & Build Quality: Top Notch The lock feels solid and well-built, with a sleek matte finish that looks great on my door. The mechanical key backup is a thoughtful touch in case of emergencies. Why I Love It It’s made my life easier and my home smarter. The design is modern and unobtrusive—it doesn’t scream “tech gadget” but blends in beautifully. Customer support was responsive when I had a quick question about app settings. this is my second lock

Once installed it worked well with the U Home app, but I couldn't add it to Apple Home despite buying this model specifically for Apple Home because they sent me a faulty unit. After a month of back and forth over email they sent me a replacement. Another month later the replacement arrived, and it worked with Apple Home, but then I could not update the firmware on my own. A month later the motor inside the lock stopped working. Save yourself a nightmare and buy something better.
