Home security is a hot topic now. More and more homeowners are looking to securing their properties with the help of home security products. However, many still don’t fully understand the full scope of the term “smart” applied to home security despite the recent technological developments.

For this reason, and more, this post will discuss the main pros and cons of the door locks available on the market. In particular, a deep look into what smart key door locks are and how they can integrate with IoT systems.

Can my front door be hacked? Is it easy to crack the system? Are smart locks secure enough? Surely, during your research online, you were seeking an answer to these questions. Congratulations, you came to the right place! The best solution for your at-home security between smart locks and traditional hardware locks comes down to networking, security, and lock quality.


What kind of door lock can be called a smart key door lock? Smart door locks are door locks that should be integrated into a network. Feel confused? Besides protecting your house, a smart lock can be integrated with different applications to bring a lot of comfort to your life. An example? You won’t need to bring any key sets with you.

Any door lock connected to your home network increases the level of security of your property. After the smart door lock is installed, it is remotely connected to the internet through Bluetooth. Using your phone, you can check the real-time reports about the latest door openings, set an anti-pry alarm, and enable other functions. You will be notified each time the door is opened. You will know immediately if someone picks the lock.

The odds of your smart door lock being hacked are really low, as the system is encrypted. The vast majority of smart locks are fairly safe. In fact, various manufacturers have made multiple steps forward for addressing this security issue.

Some examples of enhanced security features include the anti-peeping false password and fingerprint and voice access. It is easier to find skilled burglars than to find hackers who can pick your smart door lock. Neither of the two solutions can guarantee 100% unbreakable protection (watch the movie Ocean’s Eleven to understand what we mean). However, between the two, smart door locks have the edge over traditional locks in home security.


Smart door locks have several additional features to offer, including the setup of virtual passwords. This option ensures that your actual password can’t be seen when you’re typing it on the smart door lock keypad.

Smart door locks allow for a time limit that you can set for the password to be effective. This way, you will be notified after a set number of failed attempts to pick your home door.

What if someone does try to pry open the lock? You will be informed right away. If you don’t want to type the password, you can enable the feature of fingerprint unlocking. What about using your voice? All of these methods are extremely secure and hard to bypass, even for the most experienced thieves.

On the other hand, some types of traditional locks can be unlocked within one minute. It can take well-equipped thieves around 10 minutes to pick a smart door lock, during which time you will be notified, and you will have time to call the police.

Lock Quality

In terms of body resistance, smart door locks and traditional ones are both valid options. Hardware door locks are divided into ABC categories based on their anti-theft levels, where the C level is the highest.

Most of the smart key door locks on the market are lock cylinders that are above Class B. The lock body is relatively high-end compared to hardware door locks—the smart door lock is made of a metal shell, which is more delicate than the ordinary counterpart. The main difference lies in the additional function and panel design, in which smart locks tend to be harder to lockpick.

Finally, we would like to add a point in favor of the new generation of smart locks. If you are like most of us and keep misplacing your door keys, smart locks are the best option for you. This aspect also translates into thieves not being able to lift the key off you.

Final Verdict

In terms of security, both solutions are more than able to get the job done and protect your family and property. The design choice depends on you. You might be someone who loves the charm of old hardware, or rather a tech fan who keeps up with the latest trends.

The main difference is in the complementary functions and comfort that smart locks can bring to you. A few of the treats you can enjoy with a smart door lock space from saying good-bye to keys to access monitoring, multi-level security, and integration with your home assistant (like Amazon’s Alexa and Google Home).

Connect the smart door lock to your smartphone and monitor the situation of your home. Give a smart door lock a try, and you’ll find it hard to go back to regular door locks.
