Smart locks have become increasingly popular as technology continues to advance. They offer convenience and ease, allowing you to unlock your home or office doors with a simple tap on your smartphone or even using voice commands. However, as with any technology, there are risks associated with using smart locks. In this article, we will delve into the five main reasons not to use smart locks and explore the risks, latest surveys, studies, and examples that support this argument. We will also discuss the pros and cons of using smart locks, and what to consider before installing a smart device instead of a standard lock. 

1. Vulnerability to hacking and cyber-attacks 

One of the primary concerns with using smart locks is the risk of hacking and cyber-attacks. A study conducted by researchers at the University of Michigan found that several popular smart lock models were susceptible to hacking through Bluetooth Low Energy (BLE) vulnerabilities. In some cases, hackers could remotely unlock the devices without needing the digital key. Additionally, a survey by cybersecurity firm F-Secure found that 83% of smart locks tested had at least one critical vulnerability that could be exploited by cybercriminals. 

2. Dependence on Internet connectivity and power supply 

Smart locks rely on an internet connection to function properly, which means that if your internet connection goes down, you might be unable to access your home or office. This dependency on connectivity can lead to being locked out during a power outage or in situations where the Wi-Fi signal is weak or disrupted. A 2020 study by Parks Associates found that 31% of smart lock owners had experienced connectivity issues that impacted their ability to use the device. 

3. Limited lifespan and durability 

Traditional mechanical locks are known for their durability and longevity, often lasting for decades with proper maintenance. In contrast, smart locks have a shorter lifespan due to their reliance on electronic components and software updates. As technology evolves, manufacturers may stop providing updates and support for older models, leaving users with an outdated or non-functional lock. A survey by Consumer Reports found that the average smart lock had a lifespan of only three to five years, significantly shorter than their traditional counterparts. 

4. Privacy concerns 

Smart locks collect and store personal data, such as access codes and usage patterns, which can be accessed by the lock manufacturer or third-party service providers. This raises concerns about the potential misuse of personal information and the risk of data breaches. In 2019, cybersecurity company vpnMentor discovered a database containing sensitive information from over 2 million smart lock users, including email addresses, passwords, and access logs, that was left unprotected and accessible to anyone online. 

5. The illusion of increased security 

While smart locks may seem more secure due to their advanced technology, they can create a false sense of security. According to a study by the National Institute of Standards and Technology (NIST), some smart locks were found to be less secure than traditional deadbolt locks, as they could be more easily bypassed or hacked. In some cases, smart lock features like remote unlocking can be exploited by thieves who use social engineering tactics to trick users into granting them access. 

Pros and Cons: 

While smart locks offer several advantages, such as keyless entry, remote monitoring, and integration with other smart devices, they also come with inherent risks. Weighing the pros and cons of smart locks is crucial before deciding whether to adopt this technology for your home or business. 

What to do before installing a smart device instead of a standard lock: 

Before installing a smart lock, consider the following steps to ensure the best possible security for your home or business: 

  1. Research and compare different smart lock models, considering factors like encryption, authentication methods, and third-party security certifications. Look for products with a strong track record of security and customer satisfaction. 
  2. Assess your home or business's overall security infrastructure. A smart lock is just one part of a comprehensive security system. Ensure that you have other security measures in place, such as surveillance cameras, alarms, and strong window and door reinforcements. 
  3. Evaluate your Wi-Fi network security. Since smart locks rely on internet connectivity, it is essential to have a secure and reliable Wi-Fi network. Use strong, unique passwords and consider setting up a separate network for your smart home devices to minimize the risk of unauthorized access. 
  4. Create a strong access management plan. Limit the number of people who have access to your smart lock and regularly update access codes or digital keys to reduce the risk of unauthorized access. Make use of features like temporary access codes for guests or service providers. 
  5. Stay informed about software updates and security patches. Regularly update your smart lock's firmware and software to ensure it remains secure against new threats. Subscribe to the manufacturer's mailing list or follow them on social media to stay informed about the latest updates and potential vulnerabilities. 
  6. Consider professional installation. While many smart locks are designed for DIY installation, having a professional locksmith or security expert install the device can help ensure it's correctly installed and integrated with your existing security systems.  

In conclusion, while smart locks offer convenience and a range of attractive features, they also come with potential risks and vulnerabilities. By carefully weighing the pros and cons and following the steps outlined above, you can make an informed decision about whether a smart lock is the right choice for your home or business. Keep in mind that no security system is foolproof, and it is essential to remain vigilant and proactive in maintaining and updating your security measures.
