Can Smart Door Locks Be Hacked?

Key Takeaways

  • Smart door locks can be hacked, as numerous reports and studies have highlighted their vulnerabilities.
  • The design and security protocols of smart door locks play a significant role in their vulnerability to hacking.
  • Authentication methods and password vulnerabilities can be easily exploited by hackers to gain unauthorized access to smart door locks.

Smart door locks have become increasingly popular in recent years, offering convenience and enhanced security for homeowners. However, with the rise of connected devices, concerns about the vulnerability of smart door locks to hacking have also emerged. So, can smart door locks be hacked?

The answer is yes. Numerous reports and studies have highlighted the vulnerabilities of smart door locks, which can potentially allow hackers to gain unauthorized access to homes and compromise security. Let’s explore the various findings and risks associated with smart door lock hacking.

KeyWe Smart Lock Vulnerability

A security vulnerability was discovered in the KeyWe smart lock, which allowed hackers to intercept network traffic between the lock and the mobile app, giving them the ability to unlock doors. The design of the lock made it easy for attackers to bypass security mechanisms and replicate the hack. Unfortunately, the lock’s firmware does not support over-the-air updates, rendering it impossible to fix the vulnerability.

Weaknesses in Design and Security Protocols

Manufacturers’ design and security protocols play a significant role in the vulnerability of smart door locks. Weaknesses in these areas can be exploited by hackers to gain unauthorized entry. Additionally, the lack of regular updating and cybersecurity education for owners further increases the risk of hacking.

Authentication Methods and Password Vulnerabilities

Smart door locks often rely on passwords and other authentication methods to verify user identity. However, these can be easily compromised if not properly implemented. Hackers can employ various techniques, such as plain text password vulnerabilities, decompiling APK files, device spoofing, replay attacks, and even physical screwdriver attacks, to bypass authentication and gain access to the lock.

Lack of Device Access Control Systems

Another vulnerability of smart door locks is the absence of robust device access control systems. Without proper access controls, hackers can exploit weaknesses in the lock’s software or firmware to manipulate its functionality and gain unauthorized entry to a home or property.

Protecting Against Hacking

While the risks of smart door lock hacking are evident, there are steps homeowners can take to protect themselves and minimize the vulnerabilities:

  • Choose a reputable and secure smart lock system.
  • Use strong and unique passwords, change them regularly.
  • Install antivirus and encryption software on connected devices.
  • Monitor external connections and ensure secure network configurations.
  • Configure the router with a unique name and password.
  • Manage permissions and access control for users.
  • Enable multifactor authentication for added security.
  • Regularly update firmware to ensure the latest security patches are applied.
  • Have backup policies in place to mitigate potential risks.

By implementing these measures, homeowners can significantly reduce the likelihood of falling victim to smart door lock hacking.


While smart door locks offer convenience and enhanced security, it is crucial to acknowledge their vulnerability to hacking. The risks associated with weak design and security protocols, authentication vulnerabilities, and lack of device access control systems should not be taken lightly. Homeowners must stay informed about potential threats and take proactive steps to protect their homes and privacy.
