To have access to your home, you need to program your fingerprint and the system will recognize it every time you lock and unlock the door.
Keyless door locks work by entering codes that you have saved. The master code is for you, while the passage code is for other users, including family and friends. Some door locks allow you to create a special digital code for each member of your family, so you can protect your home from any unwanted intrusion.

Things to Know Before Rushing out to the Hardware Store

  • Inspect your door

    As it has been mentioned above, not all smart locks are the same. They use different technologies, different ways of unlocking and they could also have different features. That’s why, before purchasing a door lock, you need to inspect your door and see if it is compatible with the lock. Make sure your door works properly, because you may not be there all the time to lock and unlock it manually. Also, you need to check if the bolt is able to extend into the jamb. If the door jamb cannot be fully extended, your lock motor can be burnt. However, these are some issues that can be easily solved, but it is important to know about them before installing a new deadbolt.

  • Inspect the features

Also, you will want to know more about the entering methods. Some models can be controlled with smartphones, while others allow you to use a code for keyless entry.

  • Check the connections

Most people prefer to use Bluetooth because as compared to WiFi, it doesn’t consume so much power. Remember this in mind, especially if you want to use a battery powered device.

The good news about Bluetooth is that you can use it with its own hub. Most of the latest door locks work with Z-Wave standard connection.

  • Think about how to lock and unlock the door

    There are so many models on the market that it’s a bit complicated to choose only one model. The traditional locks work with the traditional keyhole, while the newest models are keyless. This means that they use something else over a keyhole. For example, most locks are equipped with a touchpad where you can use a PIN code to unlock them.
