Have you ever lived in an apartment where all you needed to do was wave a chip in front of a sensor to lock or unlock your unit? Do you recall seeing movies where a character has their fingerprints scanned before going into a fancy conference room? Have you ever used a keycard when staying at a hotel? 

If you found yourself saying “yes” to any of these scenarios, then at some point in your life, you have used a digital lock. These are just a few examples of digital lock technology you might have seen before. That said, you may or may not have stopped to consider how digital locks work in the first place. Keep reading this blog to learn more about how digital locks work and the technology they utilize. 

How Digital Locks Work: Behind The Technology

To understand how digital locks work, you first need to know that digital locks usually take different forms. The most common iterations of digital locks use keypads with PIN codes, cards or chips, mobile phone apps, and biometric data in the form of fingerprint scanning. The way keypads work is that they utilize a four-digit PIN code to trigger the release of a deadbolt. Chips and cards use RFID (radio frequency identification) technology. The chip or keycard contains a radio signal that it sends to the lock upon contact or when in proximity. Digital locks that are connected to mobile apps require a connection to WiFi or Bluetooth, which might seem precarious if there’s a power outage.

However, these locks include a manual backup, and some versions of this kind of digital lock only need WiFi or Bluetooth to make the initial connection. Another perk of how digital locks work when connected to mobile apps is that they can include an automatic log of anyone who accesses a location throughout the day. Regardless of the access tool itself, digital locks are distinct from traditional locks due to the use of an actuator. In digital lock technology, the actuator triggers the locking mechanism when a PIN code is entered, a mobile app is used, or contact is made with the card, chip, or fingerprint.

Are Digital Locks Worth It? 

Now that you understand how digital locks work, you’re probably wondering if they’re even a worthwhile investment. Whether you use a mobile app or a keypad, here are some of the benefits of digital locks that make them a worthwhile security upgrade: 

Convenience and Manageability

Digital locks are a great way to improve the convenience of your security system. It’s easy to use, and you don’t need to worry about a physical key breaking or getting lost, especially if you use your phone. Say goodbye to scrambling through your bag for clunky keys with this kind of home security. 

Improved Security 

Because you won’t have to worry about losing keys that can easily be copied by someone else, your home security will also be stronger. Additionally, a digital door lock doesn’t use a traditional lock system, so the chances of this lock getting picked are very slim.
