Unlocking Bluetooth lock with a smartphone


In an increasingly digital age, more and more buildings are relying on smart locks to help streamline building operations. Smart technology offers property managers and business owners flexibility and security — all while making access convenient. From multifamily buildings to commercial offices, a Bluetooth lock is a popular choice for keyless entry.

Read on to learn what a Bluetooth lock is and how it differs from Z-wave and WiFi locks. Then, explore the 5 best Bluetooth locks on the market.

In this post, we cover:


What is a Bluetooth lock?

A Bluetooth lock uses hands-free technology to detect whether an unlocking credential — like a key fob, smartphone, or other smart device — is nearby. The lock then authorizes this credential to grant automatic entry.

What’s more, a smart lock with a Bluetooth lock app allows you to send visitors and service providers digital keys so that they can securely access your building.

How does a Bluetooth lock work?

A Bluetooth smart lock pairs with authorized Bluetooth-enabled devices, which are used as credentials to unlock doors.

Bluetooth locks are battery-powered and don’t require an internet connection to pair with unlocking credentials. So, they may be simpler to set up than WiFi locks and other smart locks that require an internet connection. Overall, they’re a simple way to provide remote and automated access at various doors throughout your building.


How secure is a Bluetooth lock?

A Bluetooth door lock can be just as secure as a traditional lock if the network powering it is secure. A Bluetooth door lock with a camera is the most secure option because it allows you to see who’s at the door.

Consider pairing your Bluetooth locks with a secondary security measure like an access control or security camera system to increase safety at your building.

Can Bluetooth locks be hacked?

Bluetooth locks are extremely difficult to hack when installed properly. They can be quite challenging to install yourself, so it’s recommended to hire a certified installer or locksmith to carry out this process.


Bluetooth locks vs. Z-wave locks vs. WiFi locks

There are plenty of smart locks with wireless capabilities to choose from, so it’s important to consider your options to make the best choice for your building.

Let’s assess the differences between Bluetooth, Z-Wave, and WiFi locks:
