Ultraloq UL3 BT Smart Lock – My Hands-On Review

I was researching smart locks for my home office for that extra touch of security and came across the ultraloq ul3 BT smart lock. I was blown away by the features and versatility. So I decided to write a review piece covering my experiences with this lock.

I wanted to reduce the number of keys on my key chain whilst adding flexibility and additional security. This lock ticked all the boxes.

Is Ultraloq UL3 BT the perfect smart lock for you? With Ultraloq UL3 BT as your smart lock, you won’t have to use a key ever again. Its five keyless entries include fingerprint recognition, a code, an app, a knock-to-open feature for iOS as well as a shake-to-open feature for Android users.

Here you’ll find the reasons why this smart lock is just what you need. After learning its design to its performance, you might just find yourself adding this to your cart!


Metal Construction

This smart lock has a sturdy metal construction, so it cannot be easily broken should any trespasser intend to do so. Also, you won’t ever have to worry about the device’s lifespan because it’s as durable as it comes!

Another thing is that the metal design has a sleek and modern vibe. This is perfect for smart homes and houses with sophisticated designs. The classy combination of silver and black might just match your home aesthetics. 

Weatherproof Exterior

The UL3 BT has an IP65 rating, which means it can survive wet exposure. Even if you install it on an exterior door, i.e. the main door of your house, you won’t have to worry about it being exposed to the rain or the sun.

One of the things many users like about this smart lock is that it still works properly and accurately despite weather conditions.


The batteries required for the UL3 BT smart lock are three (3) standard AA batteries. What makes this an advantage is that you probably already have these in your home, and if they’re not, they’re just easy to find! 

Unlike some devices that require proprietary batteries, you will never have to worry about the battery type being discontinued.


Bluetooth Low Energy Connectivity

The Bluetooth connectivity is what allows your smartphone to connect with the device. One of the features of the UL3 is the U-tec App, and with this, your smartphone becomes your key.

Fingerprint Access

One of the keyless entry methods that the Ultraloq UL3 BT offers is fingerprint technology. With just one touch, the smart lock will identify you in less than 0.5 second, and you’ll be able to unlock your door immediately. This feature can make things pretty convenient for you especially when your hands are full and you won’t be able to twist a traditional door knob.

Also, it’s a more secure way to lock and unlock your door because every fingerprint is unique! Nobody can copy your fingerprint and then gain access to your door (unless they’re into some deep CSI sh*t!).

Lastly, the sensors are dustproof and scratchproof. This is to prevent technical issues like not gaining access because the device can’t process your fingerprint.

Keypad Code Entry

Although the fingerprint recognition may sound more high-tech than the keypad code, what’s awesome about this feature in Ultraloq UL3 BT is that it has an Anti-Peep password.

Anti-peep touchscreen helps in preventing other people from ever knowing or seeing your passcode. One of the ways to know one’s passcode is to look for the faded or worn-out digits, but with the keypad digits displayed on the screen, there is no way for someone to know your code!

The anti-peep technology also allows you to input random digits before or after the correct password to gain access. This is for those times when you think somebody’s watching you or is standing near you as you input your password and you don’t want them to see! As long as the correct passcode is embedded in the longer set of numbers, the smart lock will still identify it and give you access. Cool, huh?

Knock To Open

The knock-to-open feature is for iOS users. You’ll be able to unlock your door by knocking on your phone four times! You can use this as long as you’re within the bluetooth range.

This is particularly helpful when you’re a few steps away from your door and you need it to be opened ahead of time. Even with your phone inside your pocket, just knock on it 4x and voila! You’re in!

Shake To Open

For Android users, you can unlock your door by waking up your phone and shaking it. As long as your device is already connected to the smart lock, there is no need to open the Ultraloq app!

U-tec App

This app is what you use in your smartphone to lock and unlock your door even when you’re far away, as long as there is a WiFi connection available. It also allows you to share e-key with other users. If you’re not home and a friend needs access, you can just share your e-key with them by using this app.

Another function for this app is that it logs records. It lets you view the registered users who have entered and left the room by the use of their apps or even their fingerprints! With it, you are also able to remove and add users. You have 100% control on whoever gets to enter your home and you can monitor it 24/7. It could not get any safer than that!

Users Access

The Ultraloq UL3 BT smart lock allows up to 95 different users, and that’s 95 different fingerprints or keycodes! Although personally, I wouldn’t want 95 different people to have access to my home, still it would be nice to know that if I ever need someone to get something from my place or feed my pet, a trusted friend or neighbour could do it.


Ever get that sudden paranoia when you feel like you’ve forgotten to lock the door and you’re already miles away from home? If you have Ultraloq UL3 BT as your smart lock, you will never have to feel this way again!

It auto-relocks after four seconds, so even if you did forget to lock the door, your smart lock will secure your home for you automatically. Should you decide to not use this feature, you can also choose the option of a passage lock where your doors aren’t on auto-lock all the time.

Sense-On Recognition

When the sensor detects your hand is near, the UL3 BT smart lock automatically wakes up. The OLED display touchscreen immediately lights up which will then allow you to see the keypad better especially in dimly-lit areas.


The durability of Ultraloq UL3 BT proves that it is indeed weatherproof. It is designed to resist harsh weather conditions, which is why a lot of users choose to install this smart lock on an exterior door.

Its battery life is also another thing that makes this purchase worth it. Ultraloq brags that its battery life could last up to 1 year. It gives up to 8,000 access – that’s 8,000 locks and unlocks! When your batteries are low, an alert or notification will be displayed on the OLED screen.This helped me save time and effort because I was able to buy batteries in advance instead of actually waiting for it to die!

Ultraloq UL3 BT Smart Lock is user-friendly and is perfect for kids, adults, and the elderly. People can discourage you by saying these kinds of things are complex and hard to use because it’s high-tech. But actually, it’s pretty easy to use! It gives a smooth experience to daily users by making their lives more convenient with its five keyless entry methods.

Setup and DIY Installation

Tool and Accessory

The box includes a screwdriver and a deadbolt cover plate. These are basically the only things you’re going to need besides a door and the smart lock, of course! There is no wiring or drilling needed to install the Ultraloq UL3 BT smart lock.

A fairly-detailed manual is also provided in the box should you find yourself in a state of confusion. Although that situation is unlikely (because DIY installation is simple!), the instructions are clear as day. However, it’s advised that you still read the manual that comes with it even if you find the installation easy.

Door Size Requirement

The UL3 BT works with most standard doors. It fits just right in standard interior doors that already have a single bore hole.

With thickness between 1 ⅜ inches to 1 ¾ inches, the smart lock will fit perfectly. A ThickKit is also available for thicker doors with measurements between 2 inches to 2 – ¾ inches.

Door Handle

The door handle of Ultraloq UL3 BT smart lock is reversible. It is able to accommodate both right-handed and left-handed doors, so you can install it in whatever direction you like!


Ultraloq UL3 BT Smart Lock has over 2,000 positive reviews on Amazon. To say that this is something you’d need in your home is an understatement! No longer will you experience the frustration of losing your keys, being locked out of your own home, and being broken into because a solution has finally presented itself.

With the many features it has and the five keyless entry methods that you just won’t find in any other smart lock, Ultraloq UL3 BT Smart Lock might be the one you are looking for.
