What Are Smart Locks?

Smart locks are electronic locking systems designed to replace or upgrade your existing door lock using digital technology. Unlike traditional locks that rely on physical keys, smart locks provide keyless entry options, allowing you to unlock your door using a smartphone app, PIN code, biometric fingerprint, or even voice control through smart assistants like Alexa or Google Assistant.
These locks use wireless protocols such as Wi-Fi, Bluetooth, Z-Wave, or Zigbee to connect with your home network or smart hub. This enables remote access, letting you control or monitor your door from anywhere in the world. Some smart locks also feature auto-locking, activity logs, and guest access codes—ideal for Airbnb hosts, busy families, or frequent travelers.
With increasing demand for smart home integration, smart locks are becoming a key component of modern home security systems. They’re often used alongside smart doorbells, security cameras, and alarm systems, offering a more seamless and secure living experience. While they do require power (usually batteries), most models send low-battery alerts and have mechanical key overrides as backup.
What Are Traditional Locks?

Traditional locks are mechanical locking systems that use physical keys to secure doors. These locks have been the go-to security method for centuries and remain widely trusted for their simplicity, affordability, and mechanical durability. Common types include deadbolt locks, knob locks, lever handle locks, and mortise locks, all of which operate using a system of pins, tumblers, or bolts that require manual key operation.
Unlike smart locks, traditional door locks don’t rely on batteries, apps, or internet connectivity. This makes them low maintenance and highly reliable in power outages or technical failures. You don’t have to worry about hacking risks or software malfunctions—just insert the key and turn.
However, traditional locking mechanisms also come with limitations. Lost or stolen keys can be a major vulnerability, and physical keys can be copied without your knowledge. There’s also no remote access or monitoring, which means you can’t check or control the lock while you’re away.
For homeowners who prefer a no-frills, proven security solution, traditional locks remain a dependable option—especially when reinforced with high-security deadbolts or paired with physical surveillance systems.
