Ultraloq U-Bolt Pro Review

In the realm of home security and smart living, the Ultraloq U-Bolt Pro is a prominent contender. For this review, I’ll share my experience of using the smart lock over a period. 

This will provide an informative and practical perspective on what the Smart Lock Handle brings to the table.

Let’s jump right in.

Features and Specifications of the Ultraloq U-Bolt Pro

The Ultraloq U-Bolt Smart Lock provides versatile features for modern needs. It offers 6-in-1 unlocking options, including fingerprint recognition, keypad, smartphone control, and traditional mechanical keys.

  • 360° Fingerprint ID

Imagine this: one tap on the Ultraloq U-Bolt Pro’s fingerprint scanner, and you’re in. It’s like your personal, high-tech key. This fingerprint feature isn’t just about convenience; it’s a layer of defense for your home.

At times, reading fingerprints might take a few tries, especially with wet or dry fingers. It’s a small hassle, but not enough to outweigh the convenience.

  • Anti-peep Keypad

This feature has caught my attention for its slickness. When you punch in your code, it cleverly hides the sequence from prying eyes. It’s like your secret PIN shielded from view, giving an extra layer of security. This isn’t just for ease; it’s about keeping your code safe.

But I’ve noticed that the keypad can be quite sensitive. Sometimes, it registers accidental touches. It’s a minor hiccup worth noting.

  • Smartphone Control

Let’s discuss the smartphone control feature on the Ultraloq U-Bolt Pro – it’s quite impressive. You can use the app to unlock, lock, and share access with family, guests, or service providers. 

It offers permanent, temporary, and one-time codes for convenient entry when you’re away.

The smartphone control is remarkable; however, it depends on a Wi-Fi connection. So you might experience momentary disruption.

  • Auto Unlock and Shake to Open

Auto Lock handles locking when you leave, so you don’t have to worry about it. When you return, it unlocks as you get close to your smartphone.

Shake to Open adds a playful twist. Just give your phone a quick shake, and the door opens.

But keep in mind that these features have conditions and may raise security questions. From my experience, they’re mostly reliable but not perfect.

  • Ultraloq U-Bolt Mechanical Key

In addition to its high-tech features, the Ultraloq U-Bolt still includes a regular mechanical key. This key is a backup, so you can always get in, even if the tech has issues.

Sign and Build of the Ultraloq U-Bolt

The outer part of the Ultraloq U-Bolt is crafted from black and silver Zinc Alloy and measures about 2.9 x 2.9 x 1.2 inches

The backlit 0-9 number pad with fingerprint scanner enhances home security. An LED ring around the scanner adds a modern touch and indicates the door’s lock status.

Yet, the lock might require occasional adjustment as it can become loose over time.

App Control and Integration of the Ultraloq U-Bolt

The Smart Lock works smoothly with Alexa and Google Assistant. You can also connect it to other apps and services through IFTTT (if this, then that).

The user-friendly app is the same U-tec app (on Android and iOS). Upon opening, your locks are listed. Choose one, and you’ll find a button to lock or unlock – green for unlocked and red for locked.

However, it doesn’t work with Apple HomeKit, which is a bummer since I am an Apple user. 

Installation Process of the Ultraloq U-Bolt Pro Smart Lock Handle

Before installing the Ultraloq U-Bolt, the extensive package seemed overwhelming, yet it was surprisingly manageable. Inside, I found parts for door sides, screws, batteries, a guide, drilling template, reset tool, and a spare key. 

The instructions were clear, which made the process easy. It took me about 30 to 45 minutes to get everything set up.

The Installation Guide of the Ultraloq U-Bolt Smart Lock

Step 1: Remove the Old Lock 

First things first, take out your existing lock. Unscrew and detach it to clear the way for the new smart lock.

Step 2: Install the New Deadbolt and Strike 

Grab the new deadbolt and strike that comes with the U-Bolt Pro. Follow the instructions to fix them on your door. These parts are key to the smart lock’s operation.

Step 3: Attach the Exterior Escutcheon 

Place the outer escutcheon on the door’s exterior. Make sure it lines up with the deadbolt and strike. Secure it using the mounting plate and screws provided.

Step 4: Connect the Data Cable 

Thread the data cable through the designated opening in the mounting plate. Hook up the cable to the interior escutcheon. This cable helps different parts of the lock communicate.

Step 5: Insert Batteries 

Slide four AA batteries into the interior escutcheon. These batteries give life to the lock and its features, so make sure they’re in properly.

Step 6: Perform Handling Procedure 

Watch as the lock carries out the handing procedure by itself. This process decides whether the deadbolt faces left or right when locked. It’s crucial for smooth functioning.

Step 7: Install the Door Sensor 

Use the double-sided tape included to stick the door sensor in place. This sensor detects whether the door is open or closed, affecting some of the lock’s features.

Step 8: Download the Ultraloq U-Bolt Mobile App 

Go ahead and get the U-tec app on your smartphone. It’s available for both Android and iOS devices. This app is how you control your U-Bolt Pro Smart Lock.

Step 9: Create an Account 

Open the app and create your account if you haven’t already. Your account lets you connect and manage your smart lock using the app.

Step 10: Add Your Device 

Find the Devices screen in the app and tap the plus icon. Choose the U-Bolt Pro series from the list of locks available.

Step 11: Configure the Lock 

Once you’ve chosen the U-Bolt Pro, the app will guide you through adding the device. Set up an Admin code and give your lock a name. These settings help you identify and control your lock.

Step 12: Follow On-Screen Instructions 

The app guides you through locking the deadbolt and choosing the orientation (left or right). It also helps you connect the lock to Wi-Fi by selecting your SSID and entering the password.

I tested the U-Bolt; it responded swiftly to fingerprints and touch pad entries. It seamlessly worked with voice commands like Alexa.

Security Feature of the Ultraloq U-Bolt

The Ultraloq U-Bolt Handle is ANSI Commercial Grade 1 certified, indicating its 35 times greater strength than regular residential locks.

It lasts 7 times longer than average and holds an IP65 rating for durability against dust, weather, and temperature changes.

While impressive, installing it demands more effort than standard locks.

Battery Life and Maintenance of the Ultraloq U-Bolt

The Ultraloq U-Bolt Pro Wi-Fi Smart Lock has an impressive battery life. You can use a 5V micro-USB port for continuous security during battery issues. Regular maintenance and proper charging are vital to avoid interruptions.

Price of Ultraloq U-Bolt 

The Ultraloq U-Bolt Smart Lock might appear pricey, but its enhanced security and versatile access options make it worthwhile. Keep in mind it’s on the higher cost range, so ensure it matches your budget and requirements.


  • Has 6-in-1 access methods
  • Build to last
  • Fingerprint reader has high accuracy
  • Allows voice commands


  • The initial setup is tough
  • Doesn’t have Apple Homekit


Q1: How do Auto Lock and Auto Unlock work, and do they work with Alexa?

A: Auto Lock automatically relocks the door after a preset time, and Auto Unlock unlocks the door as you approach. Yes, it’s compatible with Alexa.

Q2: How does the lock stay locked if my phone is inside the house?

A: Once programmed, the lock operates independently with fingerprints, codes, and more. It’s accessible through various methods: fingerprints, codes, app, proximity, phone shake, or physical key.

Q3: Does the Ultraloq U-Bolt work with a multi-point lock?

A: No, it’s designed for use with a single deadbolt.


The Ultraloq U-Bolt Smart Lock has changed the way I think about home security. It offers various ways to access your home, an easy-to-use interface, and a strong build quality that balances convenience and safety. While there’s a bit of a learning curve, the benefits outweigh the minor drawbacks.
