Do Smart Locks Need Wi-Fi? (Explained!)

Most smart devices rely on wireless network technology such as Wi-Fi to connect to the internet and interact with other devices. An example is connecting your Wi-Fi compatible smartphone and computer to the internet via a Wi-Fi network. But is the process the same with smart locks? If that sounds like you, then you want to continue reading.

Here is the short answer to whether smart locks need Wi-Fi:

Wi-Fi is one of the communication protocols smart locks need to connect to the internet and communicate with other smart devices. Once successfully connected, users can remotely lock and unlock their smart locks, create access codes, and do more via a smartphone app or over the web. 

However, smart locks do not only depend on Wi-Fi for connectivity. They can also connect via other communication protocols such as Bluetooth, Zigbee, or Z-Wave, depending on a lock’s configuration.

That said, we’ll proceed to look at some reliable Wi-Fi smart locks and also examine Wi-Fi and other smart locks communication protocols.

Smart Locks and Communication Protocols: How they Work

As mentioned, smart locks rely on other communication protocols for connectivity. Below, we analyze the three common communication protocols—how they connect, effectiveness, and the drawbacks.


Bluetooth is a commonly used smart lock communication protocol and the majority of smart locks are compatible with Bluetooth. Bluetooth smart locks are also popular in most homes, perhaps because they are not so pricey and don’t drain battery quickly like Wi-Fi locks.

Connecting your smart lock to another device, say your phone via Bluetooth requires no hub, which could be another reason people prefer Bluetooth smart locks. All you need is to have the Bluetooth signals in range to connect.

However, locks that connect mainly through Bluetooth are not without a drawback, which is a limited range.

With a Bluetooth smart lock, you can’t expect to control your smart lock from a far range, let alone remotely. At best, you can control your lock from anywhere within your home—that is, if your Bluetooth range can cover your home.

So depending on your need, Bluetooth-enabled locks are good for their low battery consumption and ease of connecting to other smart devices with no hub. But you would need Wi-Fi or Z-wave locks to control your lock/door remotely.


While you can connect your Bluetooth smart lock directly to your smartphone, the reverse is the case for Z-wave locks. Z-wave locks don’t connect directly to your phone but through a Z-Wave compatible hub.

Examples of Z-Wave compatible hubs include Samsung SmartThing and the Wink Hub. With either of these hubs, you can connect your lock to your phone and other smart home systems.

And to ensure your connection is successful, you will need to place the hub within range. Z-Wave has a connection range of about 120 feet or so. Though the coverage can be extended with more Z-Wave devices.

So if you’re looking to get a Z-Wave smart lock, keep in mind you’ll need a hub before a connection can be established, and this looks like the major downside. But at the same time, it offers you the benefit of connecting to several third-party devices than a Bluetooth lock.


You probably already know about the Wi-Fi network; a wireless network technology that lets you connect your devices to the internet and also share a network between your devices.

Wi-Fi is somewhat the most sophisticated communication protocol for smart locks currently. With a Wi-Fi compatible smart lock, you can lock and unlock your door remotely, create access codes, view your lock’s log history, and more.

Wi-Fi also makes it possible to connect to the internet and integrate your smart lock with hands-free devices like Alexa and Google Assistant. Yes, you can do all this without a hub in a Wi-Fi built-in smart lock.

But Wi-Fi locks may not be your desired locks in terms of battery life. The batteries drain faster than a standard Bluetooth or Z-Wave smart lock. Though you can extend the battery life by using lithium batteries, instead of regular alkaline batteries. Even so, you may not have a long-lasting battery as other smart locks.
