Are Smart Locks Safe From Hackers?

19 minutes read

Smart locks offer convenience and can enhance security, but they also present potential vulnerabilities to hackers. The safety of a smart lock largely depends on the security measures implemented by the manufacturer, such as encryption and regular software updates. Hackers may attempt to exploit weaknesses in these systems, potentially gaining unauthorized access. Common risks include Bluetooth or Wi-Fi hacking, exploiting weak passwords, and attacking companion apps. To mitigate these risks, users should choose reputable smart lock brands, keep firmware updated, employ strong, unique passwords, and ensure their home network is secure. Despite potential vulnerabilities, when used and maintained correctly, smart locks can still provide a level of security comparable to traditional locks.

How to choose between Wi-Fi and Bluetooth smart locks?

Choosing between Wi-Fi and Bluetooth smart locks depends on your specific needs and preferences. Here are some factors to consider when making your decision:

  1. Connectivity and Range: Wi-Fi Smart Locks: These offer remote access and control over your lock from anywhere, as long as your lock is connected to Wi-Fi and the internet. This is ideal if you need to manage your lock while you’re away from home. Bluetooth Smart Locks: These locks require you to be within Bluetooth range (typically around 10 to 30 feet) for access. This is sufficient for most entryways as you approach them, but it doesn’t support remote management when you’re away from home.
  2. Power Consumption: Wi-Fi Smart Locks: Tend to consume more power due to constant connectivity requirements, leading to more frequent battery changes. Bluetooth Smart Locks: Are generally more power-efficient than Wi-Fi locks, prolonging the battery life.
  3. Features: Wi-Fi Smart Locks: Often come with more features such as integration with smart home systems, voice assistant compatibility (like Alexa or Google Assistant), and activity tracking due to constant connectivity. Bluetooth Smart Locks: May have fewer features but still offer keyless entry, simple app control, and potentially offer some limited smart home integrations, depending on the model.
  4. Security: Both types offer strong security features, but Wi-Fi locks may offer additional security options like real-time alerts and more robust user access logs. Consider encryption and other security measures that the manufacturer implements, as well as user reviews and ratings.
  5. Installation and Setup: Both typically require straightforward installation, but Wi-Fi locks might need a bit more setup to connect to your home network. Consider the complexity of the initial setup and ongoing maintenance.
  6. Cost: Wi-Fi smart locks often cost more due to their additional features and connectivity. Bluetooth locks can be more affordable, which might suit those seeking basic functionality at a lower cost.
  7. Use Case: Think about how you intend to use the lock. If you need to grant access to others while you’re not home or integrate the lock with other home automation systems, Wi-Fi might be the better choice. For simple, local access where remote functionality isn’t crucial, a Bluetooth lock might suffice.


Ultimately, the choice between Wi-Fi and Bluetooth smart locks should align with your specific needs for connectivity, features, cost, and power consumption. Consider how important remote access is to you and whether the enhanced capabilities of Wi-Fi are necessary for your use case.


How to ensure compatibility of a smart lock with existing door hardware?

Ensuring the compatibility of a smart lock with your existing door hardware involves several key steps. Here’s a guide to help you through the process:

  1. Measure Door Thickness: Most smart locks are designed to fit standard door thicknesses, typically ranging from 1 ⅜ to 2 inches. Measure your door to ensure it falls within this range. Some smart locks come with adaptors to handle doors outside these measurements, so check the specifications of the lock you’re considering.
  2. Check Bore Hole Size: The standard bore hole size for locks is 2 ⅛ inches. Measure the diameter of the bore hole and verify it’s compatible with the smart lock. Some locks might require a borehole of 1 ½ inches, so it’s crucial to match this element.
  3. Assess Backset Compatibility: The backset is the distance from the edge of the door to the center of the bore hole. Standard backsets are either 2 ¾ inches or 2 ⅜ inches. Ensure that the smart lock you select can accommodate your door’s backset measurement.
  4. Latch Compatibility: The smart lock should align with your door’s existing latch mechanism. Check whether it requires a specific type of latch and see if your current one can be used or if it will need replacing.
  5. Evaluate Keyway Type: If the smart lock uses a physical key as a backup, ensure that your existing keyway is compatible or that you’re willing to replace it with the one provided in the smart lock kit.
  6. Inspect the Strike Plate: Confirm that the strike plate on the door frame matches or can be replaced to fit the smart lock’s requirements. Smart locks might have different requirements for the strike plate alignment.
  7. Power Sources and Wiring: Ensure that the lock doesn't require complex wiring if your door doesn’t have pre-existing power connections. Most smart locks use batteries; verify that your door setup can accommodate the power needs.
  8. Smart Features and Connectivity: Check if the smart lock requires additional components like a hub or Wi-Fi bridge for connectivity, and ensure your home setup supports these features, if necessary.
  9. Installation Method: Read the installation guidelines to see if the smart lock requires professional installation or extensive modifications to the door, which could affect its compatibility.
  10. Manufacturer Support and Compatibility Lists: Many manufacturers provide lists of compatible doors or offer customer support to help verify compatibility with your existing door setup.


Following these steps will help you determine whether the smart lock is compatible with your existing hardware, ensuring a smooth installation process and functionality.


How to maintain the security of a smart lock app on your phone?

Maintaining the security of a smart lock app on your phone is crucial to protect your home and personal data. Here are some steps you can take to ensure the security of your smart lock app:

  1. Use Strong, Unique Passwords: Make sure to use a strong and unique password for your smart lock app that includes a mix of letters, numbers, and special characters. Avoid using easily guessed information such as birthdays or common words.
  2. Enable Two-Factor Authentication (2FA): If your smart lock app supports two-factor authentication, enable it. This adds an extra layer of security, requiring not just your password but also a second form of verification.
  3. Regularly Update the App: Keep your smart lock app updated to the latest version. Updates often include security patches and improvements that protect against vulnerabilities.
  4. Secure Your Smartphone: Ensure your phone itself is secure by setting a strong lock screen password or using biometric authentication like fingerprint or facial recognition. Also, consider enabling phone tracking features in case it gets lost or stolen.
  5. Review App Permissions: Periodically review the permissions you've granted to the smart lock app. Ensure it only has access to what's necessary for its core functions.
  6. Use Secure Connections: Only connect your phone to secure and trusted Wi-Fi networks, avoiding public Wi-Fi when accessing the smart lock app whenever possible. If necessary, use a VPN for added security.
  7. Monitor Connected Devices: If your smart lock allows multiple users or devices, periodically review the connected devices and remove access for any that are unfamiliar or no longer in use.
  8. Regularly Review Activity Logs: Check the app's activity logs to monitor for any suspicious activity or unauthorized access attempts.
  9. Be Aware of Phishing Attempts: Be cautious of emails, texts, or calls that ask for your smart lock app credentials or personal information. Only provide information through official, secure channels.
  10. Educate Household Members: If others have access to the smart lock app, ensure they also follow these security practices to maintain overall safety.
  11. Consider a Security App: Use a reputable mobile security app that can help detect malicious apps and fend off potential threats.
  12. Backup Regularly: Regularly back up your phone's data, ensuring you can restore important information if your phone is compromised.


By following these practices, you can significantly enhance the security of your smart lock app and protect your home from unauthorized access.
