What Exactly Is a Smart Lock?

Many assume that placing a smart lock on their front door will make their lives easier and increase their sense of security. However, what exactly is a “smart door lock,” and how does it work? Is there anything to be concerned about while installing an Internet-connected door lock?

What is a smart lock?


You might be puzzled about how a traditional lock can be described as “smart,” given that it is usually an inanimate object. “Smart” refers to the lock’s ability to communicate with other systems. An authorized user can open an electronic and mechanical locking device, a smart lock, via a wireless connection. Like your smartphone, a smart lock can also connect to your home Wi-Fi. Smart locks in a smart home make it possible to gain entry to one’s own home or grant access to others without using a traditional key. You don’t need to have a smart key fob because you can use your smartphone or a keychain fob to unlock the door. In the context of home automation, smart locks serve as an extension of security. Smart locks are connected to the internet, so it makes sense to call them an IoT part.

After learning this, the next thing you might be asking is why would you want your lock to be able to access the internet? Well, this connection allows you to activate the lock remotely and check whether it is locked or unlocked. You can monitor the status of a smart lock from anywhere in the world if you have an internet connection. Even if you are on board a plane and forgot to lock your door, an app on your phone can be used as a digital lock to give you peace of mind. Just press a button, and you’ll be able to lock the door even if you’ve been miles away. Users of many smart lock systems can send a virtual key to a third party, who can enter their home and gain access to restricted areas. Password-less entry is possible with virtual keys that can be shared via SMS, text message, or email. After receiving them, the smart lock can be unlocked for a specified time using these encrypted digital keys. There are various options for monitoring the use of a secure door, including smart locks that log access. Using a camera, some smart locks can take a picture of those who enter the door and store it in an easily accessible photo log.

Smart devices are becoming increasingly common. Many other devices can be installed in your home, including smart locks. With these devices, you have the option to set an activation time for them to begin or to create an automated program that initiates several of them at the same time. Moreover, it is possible to turn off the interior lights, close the blinds, activate your security system, and lock your door by pressing a single button on an app when you are leaving your home.

With the help of smart locks, you can now control your home’s security through various features and functions. They go far beyond the capabilities of standard locks. Many have Bluetooth and Wi-Fi connectivity, making it easier to take advantage of remote features.

  7. Enable Auto-Locking of Settings. If your smart lock has been left unlocked for an extended period, you can configure it to lock the door automatically. It is possible to activate auto-locking when you are outside your house. If your smartphone’s location is detected outside a predetermined perimeter of your home, perimeter auto-locking can lock your door automatically.
  8. Send Notifications to Your Mobile Device. Your smartphone will notify you if someone tries to break in or tamper with the smart lock. Set your lock to alert authorities or your home security provider when this occurs.
  9. Make It Work by Connecting It to Your Smart Home. Integrate your connected smart home with your door lock to activate other smart home devices. For example, you can set smart lights to turn on when the door is unlocked.
