There are two major connectivity technologies that power smart locks: WiFi and Bluetooth. Each smart door lock works to unlock your front door in its own way, offering different levels of convenience, security, and control. But which is truly better for your home? Read on as we compare the two so you can find your perfect fit.
How WiFi Locks Work
WiFi-enabled smart locks connect directly to your home's wireless network, the same one your laptop and phone use. Once connected, they're essentially always online, communicating with the manufacturer's cloud servers and your smartphone app regardless of where you are.
The setup process mirrors connecting any smart device. You install the lock, download the companion app, and follow prompts to join your WiFi network. Enter your password, wait for confirmation, and you're connected. The lock now has internet access, making it reachable from anywhere with cellular service or WiFi.
This constant connectivity is the defining feature. Sitting in an office across town? You can still check if your door is locked. Vacationing in another country? You can let in a friend to water plants. The distance between you and your lock becomes irrelevant.
Or WiFi compatible digital lock models, like the Dorset DG 406 and DG 206 models exemplify this approach, offering WiFi connectivity alongside other features like biometric access and integrated cameras. They stay connected to your network, ready to respond whether you're upstairs or overseas.
Pros of WiFi Locks
- Remote access from anywhere – unlock or check status from anywhere with an internet connection.
- Seamless integration with other smart home systems.
- Convenience for families & service providers – temporary access can be granted remotely without handing out physical keys.
- Real-time notifications for entry events.
Cons of WiFi Locks
- Higher power consumption – batteries typically for a lesser time than they do for bluetooth locks.
- Dependence on network reliability – internet connectivity issues can affect operation.
- More complex setup – requires WiFi configuration and occasional troubleshooting.
Understanding Bluetooth Locks
Bluetooth locks take a different approach. Instead of connecting to your home network, they communicate directly with your smartphone using short-range Bluetooth signals. Think of how wireless headphones connect to your phone. It's the same principle.
Installation is often simpler since there's no network configuration. Install the lock, open the app, and pair via Bluetooth. No passwords to enter, no router settings to navigate. The lock and phone find each other, shake hands digitally, and you're ready.
But the difference here is the range. Bluetooth typically works within 10-15 meters, though walls and interference affect this. You need to be physically near your door to unlock it remotely. Walk up to your house, tap the app, and the door unlocks as you arrive. But you can't control it from the office or check its status while travelling.
Pros of Bluetooth Locks
- Longer battery life – typically the battery lasts longer than WiFi locks before replacement.
- Simple setup – no network configuration required.
- Lower complexity – works directly with your phone without a central hub.
- Reduced remote hacking risk – no internet connection needed.
Cons of Bluetooth Locks
- Limited range – must be within close proximity to operate.
- No native remote access
- Less integration with broader smart home systems unless paired with extra devices.
Which Technology Fits Your Life?
Choose WiFi if you need remote access. Parents coordinating with teenage kids, people managing rental properties, anyone hosting frequent guests, these scenarios demand anywhere-access. The ability to grant temporary access to dog walkers, cleaners, or contractors without being present is genuinely valuable.
WiFi also suits people who travel frequently. Checking your lock status from hotels or unlocking for emergency access while away provides peace of mind that Bluetooth simply cannot match. If you're integrating your digital lock with broader smart home systems that rely on internet connectivity, WiFi is the obvious choice.
Bluetooth makes sense for people who value simplicity and battery life. If you're usually home when others need access, or you're comfortable with traditional key sharing, or if you prefer to use your lock as a biometric door lock, bluetooth's limitations don't impact you. The technology works reliably for the core function, unlocking your door when you arrive home without the complexity of network configurations.
Budget-conscious buyers often favour Bluetooth initially due to lower prices, though this gap has narrowed. If you're uncertain about smart locks generally and want to experiment without major investment, starting with Bluetooth is reasonable.
The Hybrid Approach
Some locks, including models in our range such as the Dorset DG 205, offer WiFi connectivity as part of comprehensive feature sets. They recognise that connectivity is just one aspect of a smart lock's value. Having the option doesn't mean you must use it, but it's there when life situations change.
This flexibility matters because your needs evolve. Maybe remote access seems unnecessary now, but what about when you start working longer hours? Or when elderly parents need occasional access to your home? Building in connectivity options future-proofs your investment.
Making Your Decision
Think about your daily patterns. Do you coordinate schedules with multiple family members? Do service providers regularly access your home? Are you comfortable managing devices through smartphone apps? Your answers point toward which technology serves you better.
Consider your existing smart home ecosystem too. If you've invested in WiFi-connected devices and value unified control through a single app, a WiFi smart door lock will integrate seamlessly. If you prefer devices that work independently without internet dependencies, Bluetooth aligns with that.
Neither technology is objectively better. They excel in different contexts. WiFi delivers convenience and flexibility for connected lifestyles. Bluetooth offers simplicity and reliability for simple security needs. Understanding what you actually need, not just what sounds impressive, leads to the right choice.
Your front door deserves technology that fits your life, not the other way around. Whether that means WiFi's unlimited range or Bluetooth's straightforward simplicity, pick what works for how you actually live. The best smart door lock is the one you'll use confidently every single day.
