We all want to feel safe and calm when we go out and while we are inside our homes. In this sense, in recent years many innovations have appeared in smart homes that try to increase security against thieves and burglars.

The clearest example is that of smart locks. They lack keys and open or close the door using fingerprint readers, coded keypads, electromagnetic cards, or remote controls. They can even be controlled comfortably via mobile phones thanks to specific applications and Bluetooth technology.

This article features the best smart locks available in the market. These locks were selected based on a series of research as well as reviews from customers. Below are 5 of the best smart locks you can find in the market.

In addition, this connected lock can be locked/unlocked via your smartphone or tablet from a dedicated application.

It works with 3 AA batteries. Its battery life reaches up to a full year, or nearly 8000 uses of the lock before exhausting its battery. The design is very professional and at the same time, very aesthetic. It can act as an element of deterrence of a possible burglar.

We continue this comparison with the August brand to present this smart lock with a rounded silver or dark gray design. Many house owners have the anxiety of losing their keys.

Receive live notifications from who just opened your door and when. It comes with an operating app that offers many possibilities.

You can fully control the locking or unlocking of your front door with a simple voice command. Manage access even from the end of the world thanks to the app. The smart lock automatically locks your entrance after 30 minutes of inactivity, which will save you a lot of stress.

Buyer’s Guide

Based on the opinions on smart locks that we’ve analyzed, here are the purchase factors to consider to find the best smart lock for you:

Design .

It should fit the style of your door. There are small and large electronic locks, with straight handles or round knobs, etc. Each brand of smart locks have their unique designs that make them stand out from the rest. Choose a design that not only appeals to you, but suits the style and design of your doors as well.

Ease of installation.

The best electronic locks can be easily installed by any user. If they are too complex, you will need to hire the services of a locksmith and the price will go up significantly.

Battery .

These devices generally run on 2 or 3 AA batteries or a USB rechargeable battery. Any of these systems can offer an autonomy of more than 1 year. The really important thing is that it has an alarm system that alerts you if its power source is running low.

Additional functions.

There are special electronic locks that can be controlled remotely via mobile apps and via Bluetooth or WiFi connection. This allows remote blocking, denying access to a specific user or key, etc.

Opening system.

It can be by fingerprint, access code, mobile application, Bluetooth, or magnetic key. Choose the one that is most comfortable for you or, better still, buy an electric lock that offers several systems for greater security.

Warranty .

At a minimum, the manufacturer must offer 2 years on them. Also, you should have a good after-sales service in case you have any problems. Check the opinions of users in this regard before opting for a specific offer on electric locks.

Price of the smart locks.

It depends. A cheap invisible electric lock can cost between $35 and $70. On the other hand, an electronic model with several opening systems, a touch keyboard, and the possibility of configuring dozens of profiles, can exceed $ 300. Although, as we have seen in this comparison, there are many intermediate options.


From the reviews above, we can see that choosing the best smart lock is not as difficult as you may have thought. Despite their varying designs, these smart locks offer the best quality in terms of security, affordability, and durability. Take your time, select the smart lock that is right for you and enjoy security at its best.
