Superb Customer Service
Let me take a moment to give a real review for anyone on the fence about buying this product or similar. After a prior smart lock (not this one) left me locked out my home in the freezing cold having to decide whether it would be cheaper to pay the locksmith quote of $200 or just break the door or one of my windows---I looked around in depth for my next lock, vowing never to be locked out again. This ULTRALOQ U-Bolt Pro lock is where all of the extensive research and reading of reviews led me. I ordered it primarily for a couple of features that were upgrades to my previous lock--first and foremost the USB where you can charge the lock from outside in the event the battery ever runs out while you're outside of the home. Secondly, I really wanted the auto unlock feature through the app/phone as you approach the door. It was easily to install, and for those who've installed locks before, it's the standard quick installation--nothing complicated or unique. While everything worked well and was easy to set up, I initially had an issue with the auto unlock feature not working as anticipated. (which again, was one of the main reasons I purchased this lock). Let me tell you, this company's customer service is through the roof top tier excellent. Unhappy about my feature not working--I vented and made a post in the community forum on their website, not even asking for anything, just venting. Well, they quickly responded and were suddenly emailing me really wanting to help resolve the issue for me. Ultimately, they sent me a replacement part, which did require uninstalling the previous part to install the new part---but I could appreciate that they were being proactive and checking in on me every step of the way. (and again, the installation was so easy in the first place that it wasn't too involved to replace.) Well let me just say, that did the trick and I am now consistently enjoying arriving to the home where the door has already unlocked for my approach. Great product, with a great team behind it. Initially I was going to give 4 stars for having the snafoo and needing to replace the part, but I think superior customer service to resolve an issue for a customer should be worth all 5 stars as well! (Bizzare things happen with all products sometimes, it's how a manufacturer responds that is remembered most)

UBOLT PRO older model better than newer model
The U-Bolt Pro that has the full green circle light indicator is the BEST model that ULTRALOQ offers. The full green circle gives you an instant indicator that your print was successful and is easily seen in all conditions. The newer model lock that has the small green check mark is a downgrade from the older model. The green check mark can't be seen in bright areas and it's frustrating to use in the daytime. I hope ULTRALOQ keeps the older U-Bolt model that has the full green/red circle around the lock. It's a satisfying action to see the green circle appear and know your print was successful. These are the best smart locks out there and I will continue to use these unless ULTRALOQ changes their locks to the small green check mark. Customers want the big full green/red circle. Make this feature your signature item of your locks and you will stand out from your competitors. I love the hidden key feature of the U-Bolt. The auto lock feature is a great idea but has some issues from time to time where the feature will stop working, but I just reset in app and it starts working again. I use rechargeable lithium batteries and they work well, but I keep and extra set of batteries fully charged on standby to swap out when needed. Takes a little effort to maintain the batteries but benefits of this smart lock definitely outweighs the effort and maintenance of batteries. I can lock/unlock via the app, which is awesome. I absolutely LOVE the biometrics fingerprint method of unlocking. My wife and I prints are stored and SUPER convenient to unlock via fingerprint. I don't want to go back to any other method. Fingerprint is very accurate and super convenient to the user. And this lock also has number keys to use as a backup with an additional hidden key feature. This lock has EVERYTHING you need. I highly recommend this U-Bolt Pro older model that has full green/red circle light over the newer model that has the small green/red check mark light. Please ULTRALOQ go back to using the full circle light. I want to see newer models but with the full circle light.

Awesome Product & Customer Service!
First of all, this lock worked beautifully from day one and was very easy to install, but when we did begin to notice some issues (over a year later), the company spent about half an hour walking em through some troubleshooting. When that didn’t work, they sent a new interior assembly, free of charge. The entire lock is now fully functional. Such a wonderful product and wonderful customer service!

Good WIFI Lock
Lock had some great features but a few things that may need to be changed.Fingerprint biometric security - One of the primary reasons I purchased this lock. If your read the instructions it's easy to set up. Also the log feature letting me know who comes in and records itThe WIFI was easy to set up. Just add you user name & passwordThe lock its self was easy to install. But the sensor was tricky as most doors have trim and had to cut the trim to mount the sensor, The dead bolt itself was the trickiest it's self bought 3 of these locks. you have to get them so lined up straight so the lock works smoothly. They also if not lined up they Jam. The Pro model dead bolt latch was messed up and jammed many times I worked hours to get it to function smoothly so it would lock on it's own. Ended up using the Schlage dead bolt latch that I had. I drilled holes out so the bolts would fit. and just like that. It worked prefect. Locks on it's own and I had it working in minutes. This I think is the main problem with this lock. It jams and you have to make sure it's lined up straight. But better yet if they had Schlage make the dead bolt latch it would be the perfect lock so This is why I give it 4 stars. If you have a Schlage latch in good shape you may want to think about using it or your might have to return it. I almost did. but after trying that it fixed it 100%. I like many of it's features. Make sure you have your bottom lock hold the door tight so the WIFI lock can lock perfectly every time.Bottom line is it's a good lock for the money, It is a little bulky and in certain doors it wouldn't work. Went with the level lock brand for the other door. And all three of my locks had troubles making the latch work smoothly one so bad I changed the latch. Sensor too was not very clear in the video as how to mount it. So this is why a 4 star. The app works pretty good.

Frustrating for so many reasons
Update: After posting this review, U-tec reached out to me via email and asked for one more chance to make it right. They actually said they would "do whatever (troubleshoot, replacement, etc) to solve the problem for me ASAP."I researched the locks they have and I knew I wanted a matter certified lock since the connection didn't work with my homey pro. I requested their new lock that has this and UWB. They responded that they're not able to give me this lock. This is the 2nd time I've requested a different lock (a different lock each time) and a 2nd time I was told no. Why did they reach out and commit to making it right if they refuse to do that?? They didn't offer anything else and they only seem to respond by email at like 3am. Their customer service has promised great service but they refuse to even stand behind their product that I've only had 6 months. One of the more disappointing and frustrating experiences I've had in a long timeOriginal review:I've had this lock installed for 6 months. I'm a fairly big smart home enthusiast and have tried connecting this device through an Amazon Echo, SmartThings, and IFTTT. I even have Homey Pro, which connects to virtually everything but I've had no luck getting this lock to consistently work.Installation: Thankfully no issues with installing the lock and for the first month or so I'd say it worked exactly as I expected.Complaints: It started by my door not auto locking. So at random times I would check my front door or leave through the front and the door wasn't locked. This was not a previous issue so I wasn't sure why it broke. I pulled up the app and discovered the lock was no longer connected to Wi-Fi. I have a Gateway Eero Pro 6E router, as well as 2 mesh Wi-Fi extenders plugged in to ensure there are no weak spots or issues with coverage. I have cameras installed further away above my garage and a bird feeder in the middle of my backyard that don't that any issues with a great connection. Despite trying repeatedly for months I've been unable to get the Wi-Fi connection stable. That's means the lock is reliant on Bluetooth. I would try for sometimes an hour or more a day to find work arounds or a different solution. I would hide the 5ghz bandwidth so only 2.4 was visible but it didn't make any difference. I tried removing the lock and re-adding it and no luck. Finally I factory reset it and once I did that the U-tec app couldn't find the lock any longer. I tried uninstalling and reinstalling the app, the lock, and other apps to control the lock. At this point I had no ability to control the "smart" lock. I reached out to customer service who insisted I try all the same things I already had. I requested they send me a new lock but they instead offered to send the interior portion of the lock. They promised I'd have it within 5 business days. I received the lock after more than 2 weeks. I installed the new part and the app was successful in finding my lock. Unfortunately it still wouldn't connect to the Wi-FiI have a long running chain open ticket with customer service. I requested they send me a new lock or a refund. They tried to continue troubleshooting with me, even asking me to disable my WPA3 setting on my router, which reduces the security of my network. I told them no and again this time requested a new Ultraloq model that is matter compliant and is the exact same cost I paid for this lock. I was told no. I asked for a refund so I can look for a better lock elsewhere and was told no. I reasoned with them that if they would give me a solution that works I would stay a customer but otherwise I would have to find a new brand with a better product. They refused again. I asked to speak to a supervisor and they refused to accommodate my request. So now I know no other option than to buy a new smart lock and forfeit the $150 I wasted on Ultraloq, not to mention all the hours and frustration.One thing for certain, I will never buy another product from them again.

Replacement Lock Shipped Under Warranty
I own 3 of these locks. Two of them are in one home about 7 feet from each other. From the start, I had connection issues with the two but eventually learned, it was was my Wi-Fi network they didn't like. Be aware that this lock does not like a newer, combined 2.4GHz & 5GHz Wi-Fi network like I had, using an Eero mesh network. I had planned to upgrade my router and once I did and created a 2.4GHz only Wi-Fi network for all my "Internet of Things" devices, their network connections have been solid since.Then one of the two locks started acting very flakey and was in the door between my foyer and the main condo space. It would emit tones at random times and then most recently it seemed to go through batteries fast. Then one evening, it was completely dead and locked me out. So I connected a battery to it via the USB port, thinking no problem. Well, it turned into a potentially very big problem because the lock did not respond to the connected battery. And due to some moving of furniture, the physical key that used to be there for such emergencies, was inside my condo. I was seriously panicking because if the lock truely was dead, I had no way inside other than to have the door forced open and potentially do some major damage. Since I'm on the top of the building on the 27th floor, there is no other way inside than through that door. After about 20 minutes of trying everything I could to get the lock to work, it mysteriously and unexpectedly lit up! I immediately put my thumb on the reader and prayed. And it opened! After all that, I made sure the key was in it's place. I also called U-tec.U-tec support answered and I explained to the representative everything that had happened. She sent me an email to completed with my contact info and proof of purchase and said they will ship me another lock under warranty. I didn't even have to send them the malfunctioning lock. Once it arrived, I installed it and tested everything. It worked as expected and I haven't had a problem since. Kudos to U-tec and their warranty support!

Favorite Smart Lock
I put these locks on the front and back door of my house and my garage door. I've been very happy with how well the thumbprint reader reacts, the ease of using the numerical buttons and the convenience of seeing the lock status on the app. I've had these longs for 2 years now and they are my favorite smart locks. One did have a piece malfunction and when I reached out to customer service they quickly mailed me a replacement part.

Amazing customer service!!!
The lock works great! No glitches. No issues. The electronics had an issue but I got warranty taken care of that. Customer service is amazing. They are prompt and will do everything to resolve any problems you have with your lock.

The “little black dress” of home security!
Elegant, sophisticated, and simple. This is not my first smart lock but it is my favorite. Construction and materials, 5 stars, ease of installation 5 stars, how it looks on your door, 5 stars.Functionality? Yes 5 stars, even though you will see hundreds of reviews saying that the wifi or the Bluetooth connectivity is NOT worth it. And that may well be true, but, read the reviews of every smart lock Amazon offers and you will see the same thing over and over.With ultraloq pro the fingerprint feature is “solid” and will be your “go to” way to get in the house. The 4 to 8 digit code will also Always work, until the battery dies and then you still have an actual Key! So, from me at least, the Bluetooth is a great way to set up the lock after installation and the wifi is hit and miss, just like all the other locks that don’t have fingerprint and touchpad entry or a physical key.I have also heard that their customer service is above and beyond, got like that.Highly recommend.

Happy with customer service!
I purchased the ULTRALOQ U-Bolt Pro WiFi in September 2025, and it has been a game-changer for our home. The installation was easy, and the fingerprint ID and auto-unlock features work flawlessly. My child is especially happy that he no longer needs to carry a house key or take off his gloves to unlock the door in -15°C weather!Unfortunately, during a home renovation, our contractors accidentally broke the door sensor. Since I am located in Canada, I was worried about finding a replacement part, but U-tec’s customer service was incredible. I spoke with a very friendly representative who understood the problem immediately. Even though I am outside the US, they went above and beyond to ship the replacement sensor to me.Everything arrived perfectly, the part fit exactly, and our lock is back to working 100%. It’s rare to find a company that supports its customers this well after the sale. Highly recommended both for the quality of the lock and the professional service!

International warranty is misrepresented
I bought this lock, it seemed to work fine for a few months. When it unfortunately stopped working during the warranty period I was told that despite them delivering the original to me in UAE, the warranty only applies if I have an address in the USA.I had no choice but to pay extra money to get them to send me a replacement. I’ve been waiting since July and I still don’t have the lock or any confirmation it has even been sent.So if you are buying this lock for the warranty or customer service then you will be sorely disappointed.

Great product and great customer support
After doing a fair bit of research, i decided to go with ULTRALOQ for my smart lock.Installation was easy, but i faced some issues with my lock after installing. I emailed support and they were very helpful. They offered to send me a new unit, which helped to solve my problem!Highly recommended and it is value for money.
