How does a Smart Lock work?

The internet of things (IoT) has come a long way in making life easier for us. It is the reason we have vending machines, thermostats, electronic appliances, speaker systems, and other appliances that makes life considerably better for us. The internet of things is also the reason we have Smart Locks. 

What are Smart Locks? 

Smart Locks are electromechanical devices that lock and unlock doors according to the instructions it receives from an authorized device. The instructions could be passed via wireless means or using a cryptographic key. 

Do you like to dig a couple of graves in your bag before you find your home keys? I guess not, especially when you are tired or carrying a ton of groceries. But don’t fret; Smart Locks have got you covered. Opening doors has never been this smart or easy. 

We live in a fast-paced era where everyone is always striving to make it to the next big thing. That means we need reminders to keep us in check because it is easy to forget little things like locking our doors. Smart Locks won’t let you forget. After all, they are designed to keep your home safe and keep unwanted people away. 

Thanks to technological advancements and its uses, Smart Locks are a must-have for every homeowner. Many homes have entirely gone smart. First, it was Smartphones that rocked the world, and then smart TVs made an appearance. 

And now? 

We have smart washing machines that can be controlled from anywhere in the world. What makes this era of smart products exceptional is how interconnected everything is. It is easy to keep track of one’s activities and appliances just by using some great applications like Siri or virtual assistants like Google Assistant and Amazon’s Alexa. 

How Do Smart Locks Work? 

Smart Locks integrate the principles of conventional mechanical pin tumbler methods and electrical methods to create a lock that is the best of both worlds. 

After installing a Smart Lock, you need to set it up with the primary device of authority – the owner’s Smartphone. After this link is set up, the Smart Lock would not accept any instructions from any device that isn’t the authorized primary device or isn’t authorized by the primary device. 

With this, the phone owner can unlock the Smart Lock from any location by using Siri or any apps that come with the Smart Lock. In addition, the Smart Lock notifies the primary device when someone tries to unlock the door; whether the person has been authorized or not. If you run an Airbnb or need to let people into your home while you aren’t around, Smart Locks can help you control your door remotely. 

Also, most Smart Locks come with a feature that reminds the owner when the door is unlocked, especially during times when the door should be locked. You can also set up lock alarms via the app such that the doors lock at pre-fixed times. 

Note that the lock mechanisms of a regular Smart Lock are the same process, which requires giving instructions via an app or through your phone’s wireless protocol.

While the mechanism for Smart Locks remains the same, the various types of Smart Locks have different lock and unlock mechanisms. Let’s take a look at some:

Fingerprint Biometric Smart Lock 

The fingerprint Smart Lock requires an authorized fingerprint. As it concerns security, fingerprint Smart Locks is one of the most secure Smart Locks on the market. This is because the cryptographic key required to unlock the Smart Lock depends on the unique ridges and swirls that make up every individual’s fingerprint. Someone could learn your password, but can’t learn your fingerprint. 

Fingerprint Smart Locks work a little bit different from regular Smart Locks. For starters, they come with a slightly different interface, which includes a fingerprint scanner. As soon as the fingerprint Smart Lock is set up with the primary owner’s fingerprint, the system reads the fingerprint and converts it to a series of numeric figures. It doesn’t save an image of the fingerprint.

Whenever a user places a finger on the fingerprint sensor, it reads the fingerprint, converts it to a numerical template, and matches it against the numerical templates saved in the system. If it matches anyone, the door will unlock. 

Fingerprint Smart Locks are known for their superb security, which is based on the uniqueness of a fingerprint. Although the system can’t be compromised easily, it can be if someone has a mold. And when this happens, changing the “password” would prove almost impossible as the Smart Lock uses fingerprint sensors. Also, a few drawbacks like wounds or scratches on the hand that interrupt the continuous ridges of the fingerprint might make the system reject authorized fingerprints. 

Facial Biometric Smart Lock 

Just like the fingerprint Biometric Smart Lock, the facial biometric Smart Lock has three components. The computer, the sensor, and software. The sensor in a facial biometric Smart Lock system scans the eye, and it does this because the eye, just like the fingerprint, is unique to every individual. This prevents any security breach.

When the sensor reads the eye, it takes note of minutia points and then converts the image to numerical templates, which are stored on the system. Each time it scans the eye, the system matches the derived numerical templates to the ones that are stored in the system. If they match, the Smart Lock unlocks. 

Facial biometric Smart Locks are more secure than fingerprint Smart Locks and regular Bluetooth Smart Locks. Their lock mechanism isn’t impervious to the fails of the lock mechanisms of other Smart Locks. 

From almost impenetrable lock mechanisms to remotely controlled lock mechanisms, Smart Locks were designed to offer high security. Their lock designs ensure that only authorized persons can lock or unlock the door. 

August Smart Lock, Reagle Smart Lock, and Yale Assure Lock with Z-Wave are a few examples of high security Smart Locks. Also, they integrate into security systems and home automation smoothly. With these locks, you can monitor who comes and goes, all from your Smartphone!
