Can Smart Door Locks Be Hacked?

Smart door locks have gained popularity in recent years due to their convenience and connectivity. However, with the rise of smart home technology, concerns about the security of these devices have also emerged. The question remains: can smart door locks be hacked?

The answer is yes, smart door locks can be hacked. There are several vulnerabilities that make them susceptible to hacking, and instances of smart lock hacks have been reported in the news. It is important for homeowners and businesses to be aware of these vulnerabilities and take necessary precautions to protect their properties.

Vulnerabilities in Smart Door Locks

There are several reasons why smart door locks are vulnerable to hacking. One of the main reasons is weaknesses in manufacturers’ design and security protocols. Some manufacturers may prioritize convenience over security, leaving loopholes that can be exploited by hackers.

Another vulnerability is the lack of updating and cybersecurity education for owners. Smart door locks, like any other connected device, require regular firmware updates to patch security vulnerabilities. However, many owners are unaware of the need for updates or simply neglect to perform them, leaving their locks vulnerable.

Additionally, smart door locks often rely on passwords and other authentication methods for access. If a weak password is used or if the authentication process is not robust enough, hackers can exploit these weaknesses to gain access to the lock.

Furthermore, the lack of device access control systems can also make smart door locks vulnerable. Without proper access control, unauthorized users may be able to gain control of the lock and compromise the security of the property.

Instances of Smart Lock Hacks

There have been several instances of smart lock hacks that have made headlines. These cases highlight the potential risks associated with using smart door locks.

One notable case involved Airbnb hackers gaining access to homes through a defective software update. The hackers exploited the vulnerability in the smart lock’s software to gain unauthorized access to properties.

In another case, Chinese researchers were able to gain remote access to a Bluetooth-enabled Yale lock. This allowed them to control the lock from a distance, potentially compromising the security of the property.

Furthermore, hackers were able to access a Schlage Connect lock with a low-cost device. This demonstrates that even high-end smart door locks can be vulnerable to hacking.

Preventing Smart Door Lock Hacks

While smart door locks can be hacked, there are steps that can be taken to minimize the risk of a security breach. The following are some best practices to prevent smart door lock hacks:

  • Choose a secure system: When selecting a smart door lock, consider its security features such as strong encryption, regular firmware updates, and two-factor authentication.
  • Use strong passwords and change them regularly: Create strong, unique passwords for your smart door lock and change them periodically to reduce the risk of unauthorized access.
  • Install antivirus and encryption software: Use security software to protect your devices from malware and encryption software to secure your data.
  • Monitor external connections carefully: Regularly check for any suspicious activity or unauthorized connections to your smart door lock.
  • Configure routers with unique names and passwords: Change the default settings of your router to prevent unauthorized access to your network.
  • Manage permissions assigned to various users: Ensure that only trusted individuals have access to your smart door lock and regularly review and update user permissions.
  • Use multifactor authentication methods: Enable multifactor authentication to add an extra layer of security to your smart door lock.
  • Insist on backup policies: Regularly back up the data associated with your smart door lock to prevent data loss in the event of a security breach.
  • Disconnect unused connections from the network: If you no longer use a connected device, disconnect it from your network to reduce the potential attack surface.
  • Take advantage of automated cybersecurity solutions: Utilize automated cybersecurity solutions that can detect and mitigate potential security threats.


Smart door locks can be hacked, and there have been instances of successful hacks reported in the news. However, with proper precautions and cybersecurity measures in place, the risk of a security breach can be minimized. It is important for homeowners and businesses to stay informed about the vulnerabilities of smart door locks and take necessary steps to protect their properties.
