Types Of Smart Locks: Key Features And Benefits

As crime rates continue to rise, many homeowners seek innovative ways to enhance their security. Smart locks have emerged as a popular solution, combining advanced technology with robust protection. The smart lock market is projected to reach USD 2.80 billion in 2024, highlighting the growing demand for secure yet convenient access to our homes.

Smart locks offer a range of features that traditional locks cannot match, such as remote locking and unlocking, smartphone control, and real-time alerts. With various options available, choosing the right smart lock can seem overwhelming.

In this blog post, we’ll explore the different types of smart locks, their key features, and what you should consider before making a purchase. From compatibility with existing hardware to essential security features, we’ll guide you in finding the perfect smart lock to meet your needs.

Categories Smart Locks Are Divided Into:

• Adapted Smart Locks: As the name suggests, these types of smart locks are adaptable, which means they can go over your pre-existing lock as an additional component to give you all the features that one might want from a smart lock, which comes without having to go through the hassle of re-installing your old lock. These kinds of locks make the transition to a smart lock very smooth and don’t disturb your lock as they are small and discreet. 
• Native Smart Locks: Native smart locks, on the other hand, are designed to be built with smart features from the start.  Features such as Wi-Fi and Bluetooth make opening the lock a wireless experience. Additionally, keypads or biometric scanners are often added to create an enhanced security factor. Due to all the built-in components, sometimes this lock may look larger than your average lock.
• Key Fob-Styled Smart Locks: A key fob-styled smart lock combines many features of the native smart lock but takes it up a notch. These types of smart locks let you unlock your door wirelessly by being able to pair it with your car keys or you can pre-assign phones to unlock when you are at the door. Some of these locks can also be encrypted or have rolling codes. Depending on the style of key fob they may also come with both a physical key fob and also have a keypad. Now that we have broken down the three main varieties of locks. Let us have a look at the main uses of a smart lock and how it can benefit us on a daily.
• Smart Locks And Their Uses: Smart locks have a variety of traits besides the regular lock mechanism. They add a layer of additional security when compared to regular key and hole locks which can be easily picked and opened apart. Features such as wirelessly and remotely unlocking your door. Also, you’re able to assign access to people, or automatically lock itself at a specific time are a few of the many features available. Smart locks let you also monitor the activity that occurs at your door. You can access information relating to who entered your house and receive a log of the activity with it. Moreover, you can integrate your smart lock with smart home systems to enhance your security.

If you often have guests, consider locks that allow for temporary guest access, which is particularly useful for hosts or when you need to grant access to service personnel. Features like auto-lock and unlock can provide convenience by automatically securing your door as you come and go. For security monitoring, opt for models that offer activity logs to keep track of who accesses your door and when.

Security Considerations

The security of a smart lock is paramount. Ensure the device uses robust encryption methods to safeguard against potential hacking. It’s also advisable to choose locks that comply with ANSI/BHMA security standards, indicating they have undergone rigorous testing. Consider locks that offer mechanical key overrides or alternative entry options as backups in case of technology failures, ensuring you’re never locked out due to a power or connectivity issue.

Compatibility And Installation

Compatibility with your current door setup is crucial. Check the lock’s compatibility with the type, thickness, and alignment of your door. The ease of installation is another important consideration; some smart locks are designed for DIY installation, while others may require professional setup. Assess your ability to install the device or the need to hire a professional, which could add to the overall cost.
