Smart Lock Connectivity: Wi-Fi vs. Bluetooth vs. Z-Wave vs. Matter
Published Date: Sep 30, 2025
Smart home technology is only as good as the connections behind it. When you choose an internet-connected door lock, you’re also choosing how that lock will talk to your phone, voice assistant, or home automation hub. Whether it’s a Wi-Fi smart lock with remote access or a low-power Z-Wave system built for smart home networks, the connection method determines speed, reliability, and integration possibilities. Keep reading as Sure Lock & Key explains the options so you can find the system that fits your needs and lifestyle.
Wi-Fi Smart Lock and Bluetooth Smart Lock: The Common Choices
A Wi-Fi smart lock puts full control of your door right in your pocket. These locks connect straight to your home’s Wi-Fi network, giving you a remote access door lock from anywhere with an internet connection. You can lock or unlock, verify the door’s position, and receive updates no matter where life takes you. The trade-off? Wi-Fi tends to use more power, which affects smart lock battery life.
Bluetooth smart locks work best when you’re nearby. It pairs with your phone when you’re within about 30 feet. This makes it a very secure app-controlled door lock because it doesn’t rely on your internet network. It’s also energy-efficient, so the batteries can last for months — sometimes even a year or more. The trade-off is that you’ll need a Wi-Fi bridge or hub if you want to control it from a distance. This technology is a clear example of how far we’ve come in the evolution of smart locks. In Sure Lock & Key’s full guide, we explain what these changes mean for your home’s security.
Z-Wave Smart Lock and Matter Smart Lock: The Smart Home Integrators
For anyone setting up a connected home or office, a Z-Wave smart lock offers dependable, long-range performance. Z-Wave devices create a secure mesh network where each device helps strengthen the signal for the others. Because it runs on a lower frequency than Wi-Fi, it’s less likely to suffer from interference — a real advantage if you already have multiple wireless devices in use. A Z-Wave lock requires a central smart home hub to connect to the internet for remote access. This setup is a favorite for many who need a reliable system, and it’s a great option for a locksmith for business to install in commercial properties with multiple smart devices.
The Matter smart lock is a new universal standard created to ensure that smart home devices from different brands can communicate and work seamlessly together. It aims to simplify the entire experience, so you won’t have to worry if your lock works with your speaker or thermostat. It runs over Wi-Fi and Thread (another low-power mesh network) and promises improved security and easier setup. As more Matter-certified devices become available, it will likely become the go-to for a hassle-free, unified smart home.
Choosing Your Connection: Smart Lock Battery Life and Installation
So, which one is right for you? For most people, the decision comes down to balancing convenience with smart lock battery life.
- Wi-Fi smart lock: Best for direct remote access, but expect to change batteries more often.
- Bluetooth smart lock: Excellent battery life and security, but no out-of-the-box remote control.
- Z-Wave smart lock: Great reliability for a whole-home system, but requires a hub.
- Matter smart lock: The future-proof choice for universal compatibility.
