Increased Security

No more wondering if your door is locked and closed. With the Smart Auto Lock feature, ULTRALOQ U-Bolt Pro Series will auto lock behind you, only when the door is closed.

This was a replacement lock for a preexisting dead bolt. It fit perfectly within the door. The Ultraloq U-Bolt Pro WiFi is simple to program, works every time, connects to Wi-Fi without missing a beat. The auto lock feature works perfectly as well so there is no chance of leaving the door unlocked by mistake. This is a purchase you will be happy with for years to come.

Ultraloq U-Bolt Pro Wi-fi lock

Very happy with this smart lock. Very user friendly.

Nearly perfect.

Pretty easy install. Biggest part is to stop at each step and make sure your bolt slides in and out of the frame receiver freely without binding. The only issue I have is the auto unlock. It's worked once out of the dozens of times I've approached my door. Fingerprint works great. Code works as expected. Just the one feature that is the most appealing to me seems to not be fully developed yet. That aside, it's a great lock that I'll keep.

ULTRALOQ U-Bolt Pro Series

This is our third Ultraloq lock. Our experience with our first two Ultraloq's has been great, which made this third purchase an easy decision. While our first Ultraloq is a bit finnicky with the fingerprint reader (at times it has difficulty sensing my wife's finger and requires more than 10 attempts before she chooses to use the app on her phone), it was not a negative to our third purchase. Customer service with problems on our first Ultraloq was outstanding, and a definite plus in the decision to purchase our 2nd and third Ultraloq. The new app also makes the integration and management of all three units very simple. Now specifically to the third Ultraloq - it is the Ultraloq U-Bolt Pro series. It came with great installation procedures and videos, making the installation very straight forward and simple. It is definitely an improvement over the first two Ultraloq's, albeit the installations were very simple as well. Since the unit is installed at our vacation home, there has not been much experience beyond the initial installation. I am able to remotely monitor it, lock or unlock the unit which could come in handy when a family member choses to be at the vacation home without a key in their pocket. First impressions with this new lock are very positive, and with the summer just breaking out, we will get more experiences under our belt in the coming weeks.

Ultra Loq Pro

I installed my lock on my garage side door. The install was easy and straightforward. I love the door sensor and the auto lock feature. It’s a great addition and I plan on ordering more for the other doors for my house.
