What is a smart lock and what are its advantages?

We refer to a security mechanism that is mainly integrated into doors. But it could also be added to windows, drawers and cabinets. It is controlled remotely by voice command via a mobile device, by fingerprint or by simply dialling the passcode on its keypad.

Thanks to technological innovation, manufacturers have improved the security provided by these devices. Therefore, anyone can use them, as long as they know how to do so. Additionally, they are easy to install, have an automatic locking system, and accept the configuration of eventual guest codes.

But that is not all. Smart products are presented as an alternative on the market that facilitates the modernisation of internal processes in the home or office. In this way, they offer the possibility to leave aside the traditional way of operating a lock using keys that can easily be lost.

Traditional or invisible smart lock - what should you look out for?

You will find different types of products on the market. This is the reason why we want to introduce you to the most common ones. Take a look at the features of each option and determine which one best suits your personal needs, always taking into account the place you want to secure.

Traditional. It has a keypad made up of 3 or 4 columns with numbers and symbols. It is a very practical variable for those who intend to protect their home or business belongings. On the other hand, it is easy to install, as it only covers a small area of the door.

As it is for indoor use only, you can also place it in wardrobes, rooms and cellars. Of course, it is powered by AA batteries, which is something to consider before taking it home, as the way the batteries are charged determines their lifespan. It sometimes serves as a backup method for conventional locks.

Invisible. It stands out among the usual models because it does not have a cylinder in sight through which it can be manipulated. It therefore requires the programmed action of a remote control or mobile phone to operate it. It has become popular as an invisible smart lock, which is located on the inside.

Thus, it is capable of converting an ordinary wooden or metal door into a maximum security system. Those who decide to purchase this product should bear in mind that the remote control is battery operated, just like the lock. Additionally, it has buttons for manual opening and closing in case of emergency.

Traditional Invisible
Visibility Yes No
Installation External Internal
Batteries 4 AA alkaline batteries 2 AA alkaline batteries
Emergency protocol No Yes

We are pleased to welcome you to the most important segment of our instalment on technological locks. Here you will find quality material about the factors that allow you to compare the qualities of the various models for sale on the internet.

  • Identification
  • Add-ons
  • Applications
  • Installation


We are sure you have wondered how smart locks work. It is precisely this factor that determines how you will use it from the moment it is installed. Choose the one with the recognition system that makes you feel comfortable in the short, medium and long term.

Bluetooth. Do you do your most important activities on your mobile phone? Take home a copy that is activated by this mechanism. We especially recommend it because it will allow you to open and close doors with just an identification code, which you can share with guests, for example.

Wifi. If you are attracted to process automation, consider purchasing a product that works through your home or work Wi-Fi connection, to which your phone is integrated. This mechanism is able to recognise only your personal password, so you will avoid fraud and theft.

Biometric: Do you want a state-of-the-art lock? Opt for a biometric lock to reinforce the security of your company, business or private institution, preferably. Take advantage of its ability to identify physical characteristics such as voice, face, fingerprint and iris.


In order for these devices to work optimally, it is necessary to combine them with accessories designed for this purpose. Here we show you which ones you should integrate into your online purchase, as sometimes you have to take them separately, as they do not come with the product.

Batteries. Check the description of the item to see what type of batteries it requires. Take into account that traditional and invisible locks usually require 2 or 4 AA batteries. Remember to change them according to the manufacturer's recommendations to prevent the equipment from stopping working.

Mobile phone. If you are thinking of acquiring units that automate processes thanks to their Wifi or Bluetooth identification system, we suggest you have a latest generation iOS or Android mobile phone at hand. Keep in mind that without either of these two accessories, they will not work.

Remote control: Does the idea of buying an invisible smart lock appeal to you? Then the right thing to do is to get it in conjunction with a remote control. Check if the device is sold separately. If so, look for one whose features guarantee the programming of the device.


In particular, there are two types of environments where it is best to enjoy the functions of these devices. Think carefully about which presentation suits the needs of the room and the people who live there on a daily basis. Take a look at the following to help you make the right choice.

Do you want to ensure the wellbeing of your family? We suggest you purchase a traditional lock with a built-in keypad. Place it in the internal rooms of the home, cupboards and drawers. In addition to this, consider that it will be useful when it comes to protecting personal belongings.

Business. Now, if you have your own business, the best thing to do is to add to the security system invisible smart units, biometric, and even with identification capacity via Wifi or Bluetooth. Why? This way you will have state-of-the-art models that are up to date with privacy mechanisms.

Where to install the lock? Fortunately, there are only two easy-to-understand alternatives and here are the ones. See if one or both are suitable for the applications you have in mind. Remember that making the wrong choice could affect your goals.

Interior. Luckily any variable is suitable for indoor spaces such as bedrooms, studios and storage rooms, because they should not be able to withstand adverse weather conditions. In this sense, our suggestion is that you opt for one with a traditional or remote-controlled identification system.

Outdoors. On the other hand, when the device must be installed outdoors, it is best to look for a lock with a protective metal frame. For example, the smart invisible ones are a great option for you, as with proper protection they will keep their own electrical system intact.
