The era of “smart” devices has taken over today’s world in many ways. One such trend that has gained momentum are smart locks.

And if you’re wondering how they work, then you’ll find the answers you need here.

I’ll share the ins and outs so you can determine if these products are the right choice for you or not. And, if you do decide that it’s a good fit, I’ve got another helpful guide so you can be sure you’ll get a good deal, more on that later.

What You Need to Know Before Buying a Smart Lock for Your Door

A smart lock can prove to be a convenient luxury for many families. It addresses concerns relating to security that’s ineffective through conventional means.

Some people may question if they need a smart lock for their door, but having one is an exponential upgrade from basic functionality. These products can make life easier, giving you a sense of control and constant notifications on when the front door should be locked.

Now, let’s dig into the details on how a smart lock works.

How Does a Smart Lock Work Exactly?

A smart lock has a keyless lock that allows you to unlock your front door without the need for a physical house key. In short, these products allow you to lock and unlock your door without the need of a physical key.

The product can be accessed through a mobile phone app for your smart home. Certain products have a keypad embedded on the lock so that an access code can be entered.

The lock connects to your home’s WiFi so you can lock or unlock your door anytime. This is what allows the lock to receive the code, or for the mobile phone to command to either lock or unlock your door.

Certain intelligent locks require a complete replacement of the lock system, but others can fit right over the existing setup on the door.

Smart Home Technology

When the product is integrated into a smart home, advanced locks can connect themselves with other devices, such as a speaker or security system. However, this would require a specialized hub that allows all of the devices to co-exist with other smart products. This can be a great addition to your smart home. Check out Protection 1.

The power to connect your smart products with Bluetooth technology comes into play here.

As long as there’s a stable connection, you’ll be able to have access to your lock and other valuable information. These information includes:

  • push notifications that you can customize in your phone’s settings
  • a log of who has accessed the home (or attempted to)
  • the ability to send out virtual keys

This kind of lock uses virtual keys and temporary codes that are sent from your smartphone to another person’s phone. This allows that person to enter your home without you having to be present.

Intelligent locks come in handy in terms of organizing your security. If you happen to notice someone who shouldn’t be at the house at a specific time, you’ll see it through either failed attempts or a notification sent out.

You’ll be able to tell precisely when someone who lives in your home has arrived or left (i.e., children getting home from school or a family member that leaves without your permission). In this way, you can get a real-time notification if someone unlocked the door and is about to leave.

The best part is you only need to connect it using a mobile phone to make this all work.

Additionally, we’ve all had times when we’re in a rush and either misplace our keys or forget to lock the front door when we leave. Instead of having to rely on the conventional key or go all the way back home to lock the door, all you have to do is download an application on your mobile phone. That will provide you with everything that you need to enter to your home.

Another advantage is that you won’t have to fumble with your keys to unlock your door when you just arrived with your hands full of grocery bags. You can unlock the door before you come out of the car. Or there are other devices that allows you to unlock your door using a sound command.

Doubtful events will be notified on your mobile device via the available Integrated Automation System. This will also allow you to continue monitoring your smart home. Some smart locks automatically once it detects that you hadn’t locked the door (when you left or if you’re inside the house already).

With its Connectivity convenience, some smart locks can also be connected to voice command devices available like Amazon’s Alexa and Google Assistant.

With this digital sound command technology, you can now lock your front door without lifting a finger, and it just needs to hear your command. You can create a command and connect to Alexa or Google and say, “Hey Alexa, lock the front door.”

It doesn’t get more convenient than this. However, most smart locks do not come available with this feature, so it’s something you should consider before picking the smart lock for your home. Also consider which sound command devices can connect to your wireless door lock.

4. Custom Rules

Other smart locks allow you to create custom rules for your convenience. Like for example, upon entering your home, you can set 20 seconds for the doors to automatically lock in case you forgot to lock them.

Or you can set a custom rule where the lights will automatically turn off, adjust the smart home’s thermostat system, and then enable your smart home’s security system upon locking of your front door.

Of course, these custom rules and features depend on the brand and manufacturer of your smart lock.

You can also set a system before you go to sleep. This is to save your effort in checking all doors are locked and checking all the rooms in your house if lights need to be turned off. Another notable feature however, is smart locks also sync with your thermostat system to adjust automatically.

5. An Advantage for Business Owners

Smart locks are not only designed for residential use but commercial use as well. This can be an advantage to business owners who want to make sure that only authorized personnel can enter the premises.

With the convenience of personal access codes, each employee can have their code. This will be helpful to the business owner in tracking who came in or went out during a specific period.

This will also give peace of mind to the business owner if the employee comes in late for work, or leaves early. Because of the recorded history of all coming and going employees sent to the owner’s mobile phone, this can serve as proof of attendance for the employees.
