Smart locks are revolutionizing the home security landscape. They allow you to lock your home without a physical key. At the same time, more advanced options give you features like the ability to unlock from a remote location, track your activity, or integrate with smart home systems. But how does a smart lock work? In this guide, we’ll simplify the technology, the components, and the benefits of smart locks so that by the end, you’ll see why they’ve become a popular option for today’s homeowners.
Understanding a Smart Lock?
A smart lock is an electronically operated keyless lock that helps you out from not carrying a physical key to unlock/lock your door. Instead, it provides access through digital technology like Bluetooth, Wi-Fi, or biometrics. Smart locks are meant to replace or supplement traditional deadbolts, providing a more secure and convenient means of controlling who comes into your home.
Smart locks can be locked and unlocked with an app on your phone through voice commands or even with a fingerprint, while traditional locks can only be locked with a physical key. They also enable you to track who comes in and out of your home in real time with activity logs and alerts, so they are an excellent option for anyone looking to overhaul their home security system.
Covering Smart Home and the Internet of Things (IoT)
We need to know their significant components before understanding how smart locks work. Here’s a summary of its key components:
Electronic Motor Unit: The physical locking mechanism that locks/unlocks the door. The smart lock’s onboard processor governs this.
The wireless communication module enables the lock to communicate with your smartphone, Wi-Fi network, and other smart home devices.
Wired Vs. Battery-Powered: Most smart locks run on batteries, but some can be plugged directly into your home’s electrical system.
Digital Keypad or Touch Interface: Smart locks often include a keypad or touch screen for entering PIN codes.
Key Override: For safety reasons, most smart lock models come with a backup keyhole.
Integration with Mobile App: The app acts as the main control center for the smart lock, where you go to lock/unlock the door, control access, and track activity.
How Smart Lock Technology Works
Many smart locks use a combination of mechanical and digital systems. When you unlock the door via any authorized method, such as entering a PIN, using your smartphone, or scanning your fingerprint, the lock’s internal processor cross-references your credentials. Upon verification, the electronic motor will lock or unlock the door depending on the user’s command.
A mobile phone app, for instance, sends a signal to the lock via Bluetooth or Wi-Fi. The lock receives the signal and executes whatever action is requested. It takes place in seconds, providing a smooth and secure experience.
Smart Lock Authentication Methods: Smart Lock Types
Smart locks are so helpful because there are many ways to unlock them.
Here are the most popular authentication methods:
PIN Codes: Many smart locks have a keypad where you type in a personalized code to unlock the door.
Mobile App: Most smart locks have a mobile app that allows users to manage the lock remotely. It is beneficial for letting guests in when you’re not at home.
Biometric Scanning: Certain smart locks have fingerprint scanners for enhanced security.
Key Cards or Fobs: Similar to hotel room keys, tapping this card or fob against the lock will unlock the door.
Voice Control: If you have a smart lock compatible with a virtual assistant, like Alexa or Google Assistant, you can use voice commands to lock or unlock your door.
Traditional keys: Most smart locks still have a keyhole as an alternative.
