Shopping guide

There are many security devices on the market, so it will not be easy to choose the most suitable one for you. In the previous comparison of smart locks we have shown you several of the best on the market and now, we will explain the main factors that you should look at when choosing the one that best suits your needs.

opening type

The first point of our guide to buying the best smart lock starts with the types of opening. Although most of these locks have some type of interaction and connectivity with the mobile phone, they also usually have other opening methods that should be known before choosing.

Some have fingerprint access. They are usually the most used in spaces where a lot of security is required, such as banks, offices or public centers with restricted access. These locks have biometric readers that record people’s fingerprints and create credentials so they can gain access just by touching the lock.

Other locks have access through coded keys, key fobs or RFID cards. These usually have options to configure several cards or keys, allowing access to several users. There are those that retain the traditional lock, which allows the user to combine his lifelong key with one of the other opening systems.

The locks that have a mobile application allow you to open and close the door from anywhere using the phone. These models also usually have automatic locking and opening, which open or close the door when we move away or approach it. 

Other opening systems are passwords. In this case, you should look for a lock that has some kind of application with which you can control passwords, create and configure them. It would also be a good idea to have some kind of double authentication as passwords can be hacked and this system improves security.

Finally, some smart locks have some kind of remote control that allows you to easily open and close the door.


Smart locks must have some system that allows them to communicate with other devices, be it a mobile phone, a tablet, a key fob, an RFID card or a remote control. Usually, how much the lock costs will depend on the connectivity, since the most expensive ones will be those that have several options such as WiFi and Bluetooth.

The most common and what you should look for in a good and cheap smart lock is that it has, at least, a Bluetooth connection. It is a type of low consumption connectivity, although it has less range, since it will not work beyond 20 meters, although it is enough distance to control a door lock. Bluetooth is also usually the best option to connect with the smartphone.

The most modern ones have WiFi connection. In this case, you will be able to control the lock from anywhere, as long as your phone has an Internet connection. They work with the home router and are perfect for managing who enters the house at all times or opening from work.

Finally, some smart locks have a Z-Wave connection. This is a rather rare type of connection, which requires a special repeater that converts the Z-Wave signal into Bluetooth or any signal compatible with the phone. It is not entirely recommended, since it requires an extra investment.


Some smart locks have compatibility to work with virtual assistants like Google Assistant, Siri, or Amazon Alexa. This compatibility allows you to manage the lock through voice commands or by creating routines, for example, you can ask your assistant to close at a certain time and open at another. 

It’s also possible to connect the lock with services like IFTTT to create routines like opening the door when you’re coming home from work. Keep in mind that the Internet of Things is very dynamic and changes very quickly, so you have to be careful when choosing one of these locks, as it could become obsolete very quickly.

Programming and access control

Continuing with the previous point, some smart locks allow you to program the closing and opening, either through a digital assistant or through their own applications. This is an interesting factor, for doors of commercial premises or public places that always open at the same time.

Others include systems to configure passwords, cards or store fingerprints to create access. This is like being able to give a key to a family member or friend, so it may be convenient to choose a lock that offers you this possibility.

Frequently asked questions

Q1: How to install a smart lock?

In most cases, smart locks are designed to be easily installed. To do so, all you have to do is remove the original door cylinder, which can be done with just a screwdriver and in less than 5 minutes, and replace with the new lock. 

When carrying out the installation, it is advisable to read the user manual carefully, to familiarize yourself with each part and with the assembly process. Some products include all the necessary tools as well as the appropriate screws, but others do not. In the case of not having all the material, do not disassemble your original cylinder until you have all the screws and parts necessary to assemble the new lock. 

Once installed, check that it works well and that the cylinder closes well. Try a couple of times, opening and closing the door, to make sure everything works correctly.

In case the lock has cables or a more complex installation system, the best thing you can do is to have a locksmith who will be in charge of the installation. Remember that a lock must be perfectly installed or else they could break into your house or, worse still, it could malfunction and leave you out of the house.

Q2: How to open a smart lock?

Each lock has its opening and closing methods. The best smart lock will be the one that offers you more than one option, for example, one that allows you to open using a mobile application, a password and a key or RFID card. Some allow opening through a biometric reading of the fingerprint and others do it using numerical passwords.

Some smart locks allow you to keep the traditional key, thus offering an extra layer of security to your home. 

Q3: How does a smart lock work?

Although, as we have just explained, each one has its own opening systems, almost all smart locks have a similar operation. They have an electric or electromagnetic mechanism that is responsible for keeping the door closed until it receives an opening indication from the device controller.

Electronic or intelligent locks provide an identification system or “credential” which is what authorizes the electromagnetic lock to open or close. To open the door, the user must show that credential. In reality, it is a system very similar to a smartphone lock, since the door is opened through a unique PIN, password or fingerprint.

Q4: How to make a smart lock?

A smart lock must be very secure, since it will be in charge of the security of your home, so we do not recommend making one, but it is much better to buy it. 

In any case, it is possible to make a smart lock with a Raspberry Pi, creating a deadbolt -type system that, installed on the door and connected to the smartphone, allows you to control the closing and opening of any door. This is a complicated process, but you can find video tutorials online that will explain how to do it.
