Are Smart Locks Safe? Things You Need to Know

Smart locks offer homeowners the convenience of remotely controlling access to their properties and emerge as a convenient and innovative solution for modern security needs. These smart devices utilize wireless communication technologies, such as Bluetooth, Wi-Fi, or Zigbee, to connect with homeowners’ smartphones or other authorized devices.

While Internet connectivity has brought many advantages to this device, some security concerns have arisen among many homeowners. So are smart locks safe? The answer to this question may depend on your specific security needs. With advanced security features, smart locks are secure enough to safeguard your front door security.

How Secure Are Smart Locks?

The security of smart locks can vary based on distinct factors such as brand, model, and specific implementation. Installing smart locks can satisfy basic security requirements since most devices have particular security features, including built-in alarms, tamper detection mechanisms, and the ability to track access history. However, like any other technology, they are not immune to hacking or technical malfunctions. Users need to take specific measures to enhance the security of smart locks.

Traditional vs. Smart Locks: Which is Better for Security?

When discussing smart locks, we must pay attention to the traditional ones. Traditional locks have stood the test of time and play a role as reliable methods to secure homes. So which one is better for security: smart locks or traditional locks?

Traditional locks utilize mechanical mechanisms to safeguard properties. They don’t rely on power sources or network connectivity. As a result, they can work well during outages. On the other hand, smart locks can be controlled remotely through smartphones, tablets, or voice assistants. Many of them have features like keyless entry and guest access codes. Smart locks provide users with a higher level of convenience and customization.

Regarding security, smart locks have potential vulnerabilities since they rely heavily on the network. These vulnerabilities include hacking risks and other potential cyberattacks. Traditional locks are also vulnerable to brute force. Intruders can easily pass them over using physical tools or kicking in the door.

The decision between the security of traditional and smart locks ultimately depends on your specific security needs and personal preferences. Traditional locks may be your preferred choice if you prioritize simplicity, durability, and a proven track record. However, a smart lock could be the perfect fit for your home if you require modern features, such as remote control and seamless integration with other smart devices.

Advantages of Smart Locks

People need a smart door lock mainly because of the incredible benefits that smart door locks offer. Here are some of the unparalleled advantages of smart locks.

  • Convenience at Your Fingertips: Smart locks provide users with more comfort, and smartphone apps or other authorized devices can control them. Users can utilise this remote control functionality to lock and unlock the door from anywhere in the world with an internet connection.
  • Keyless Entry: Many smart locks eliminate the hassle of physical keys. This feature can be good news for forgetful people. Users can enter homes with passwords, fingerprints, or facial recognition. Besides, using a key code means homeowners won’t worry about a stray key falling into the wrong hands.
  • Activity Tracking: Some advanced models have built-in AI algorithms that can help you track who comes and goes with alerts sent from your phone. This functionality can be beneficial for effective guest management and access control.
  • Combination with Smart Home Systems: Smart locks can work in tandem with other smart home devices and communicate directly with your hub. This compatibility enables you to customise the settings of your smart lock and improve overall home security.

Possible Concerns about Smart Lock Security

Smart locks come with some potential vulnerabilities and security concerns. Common security concerns include hacking, lock failures, and user errors.

Vulnerability to Hacking

Smart Locks can be susceptible to hacking. Like any other connected device, smart locks rely on technology and communication protocols that hackers could exploit. While many smart lock manufacturers implement robust security measures, no system is immune to hacking attempts. Users should apply adequate security measures, such as two-factor authentication and strong passwords, to avoid hacking or other cyber attacks.

Power Outages and Lock Failures

Like all electronic gadgets, smart locks rely on a power source to function efficiently. The most common power sources are battery and hardwired. The batteries in smart locks only last for a certain amount of time, and home electricity may experience outages. When a smart lock’s power source dies, several consequences may occur, including the inability to unlock the door, inactive automatic features, and limited entry methods. Fortunately, most smart door locks have a traditional keyhole as an emergency backup solution.

Complexity and User Error

The technological complexity of smart locks may lead to user errors. User errors for smart locks refer to mistakes or oversights made by individuals interacting with the smart lock system. These errors can include entering incorrect PIN codes, forgetting or misplacing access credentials (such as a smartphone or key fob), failing to properly configure or set up the smart lock, or unintentionally sharing access codes with unauthorized individuals. User errors can lead to lockouts and security breaches. When choosing smart locks, you can check out the interfaces to ensure they are user-friendly.

How to Enhance Smart Lock Security

When using smart locks to protect your front door, you can try the following tips to enhance their security.

1. Regular Software Update

Smart lock manufacturers are committed to avoiding potential threats by providing regular software updates. These updates not only introduce new features but also address any identified vulnerabilities. Regularly updating the software of your smart locks can help them remain a powerful barrier against unauthorized entry.

2. Set Strong Passwords

When setting up your smart locks, you first need to set strong and unique passwords for your mobile app or web interfaces. You can use a combination of letters, numbers, and symbols to make them hard to guess.

3. Enable Two-Factor Authentication (2FA)

You can also enable two-factor authentication if your smart lock system supports this functionality. Not only requiring a username and password, the 2FA process asks users to provide two different authentication factors before accessing an application or system. These additional factors include text message codes or fingerprint scans.

4. Connect to Secure Network

Smart locks heavily rely on wireless internet connectivity. Set up a strong, encrypted Wi-Fi network with a unique password. Avoid using default or easily guessable passwords for your Wi-Fi router, and do not connect your smart lock to public Wi-Fi. It is highly recommended to use WPA2 or WPA3 encryption for enhanced security.

5. Integrate with Home Security Systems

Integrating smart locks with a home security system can be a strategic move for those seeking an added protection layer. Combining your smart lock with security cameras, motion detectors, or alarms can create a comprehensive security ecosystem that deters potential intruders and swiftly alerts you to suspicious activity.


In conclusion, most smart locks can satisfy basic security requirements for users. However, these devices have some security concerns since they rely on network connections and communication protocols. You can take some effective measures to enhance the security of your smart locks and safeguard your home more effectively.
