Smart digital door locks have quickly become popular for homeowners looking to upgrade their security. These advanced systems offer keyless entry, remote access, and enhanced control over who can access your property. However, just like traditional locks, they require thoughtful usage and proper care to ensure they provide maximum security.
If you’re considering installing a smart lock or already have one, it’s crucial to understand the safety practices that keep your digital lock functioning reliably. Below, we explore the most important safety tips to protect your home and maximise the benefits of your smart locking system.
1. Use Strong, Unique Access Codes
A major advantage of smart locks is using PIN codes instead of physical keys. However, the effectiveness of this feature depends on your use of strong and unique codes.
Why Strong Codes Matter:
Using predictable or easy-to-guess codes like “1234” can make your lock vulnerable to unauthorised access. Hackers or someone with basic knowledge of common code patterns can easily exploit these weaknesses.
Best Practices for Setting Access Codes:
- Avoid simple codes: Refrain from using easily guessable combinations such as birth dates or repeated digits.
- Create unique PINs: Use a unique PIN code for each user, especially if you allow different people access, such as family members, cleaners, or service providers.
- Regularly change the codes: Update your access codes periodically, particularly if there has been any concern about who may know them. This is especially important if you’ve provided a temporary code to guests or contractors.
- Limit access: Smart locks often allow you to set temporary access codes that can expire after a certain time. Use this feature when giving access to people like dog walkers or house sitters.
Ensuring your access codes are complex and updated is a simple but crucial step in keeping your digital door lock secure.
2. Keep Your Smart Lock’s Firmware Updated
Like any other smart device, your digital lock’s firmware will occasionally receive updates. These updates are essential to fix bugs, enhance performance, and close potential security gaps.
Why Firmware Updates Are Crucial:
- Security patches: Manufacturers often release firmware updates to patch vulnerabilities that hackers may exploit.
- Performance improvements: Updates may also enhance the functionality of your lock, ensuring it operates smoothly and efficiently.
- New features: Some updates may add useful new features, improving the overall performance of your lock.
How to Stay Up-to-Date:
- Enable automatic updates: If your smart lock is connected to Wi-Fi, enabling automatic updates will ensure that your lock is always running the latest software.
- Manually check for updates: Periodically check your lock’s companion app or the manufacturer’s website.
- Ensure strong connectivity: If your lock depends on Wi-Fi or Bluetooth to operate, ensure it has a reliable connection to avoid missed updates.
By keeping your smart lock’s firmware current, you can ensure the highest level of protection against emerging threats.
3. Secure Your Lock With Biometric Features
Many advanced digital locks come with biometric features, such as fingerprint or facial recognition, for an added layer of security. These features provide a high level of protection as they rely on your unique biological data.
The Benefits of Biometric Security:
- Difficult to replicate: Unlike codes, fingerprints or facial data are nearly impossible for unauthorised individuals to mimic.
- Convenience: You won’t need to remember a code or carry a key—your fingerprint is your access key.
- Reduced risk: There’s no fear of losing a physical key or someone discovering your PIN code.
How to Maximise Biometric Security:
- Ensure accurate setup: When setting up fingerprint or facial recognition, follow the manufacturer’s instructions carefully to avoid errors in the recognition process.
- Regularly clean the sensor: Dirt or moisture on a fingerprint sensor may prevent it from functioning properly. Wipe the sensor regularly with a soft cloth to ensure it’s clean and functional.
- Backup methods: Always have a backup access method, such as a PIN code or a traditional key, in case the biometric scanner malfunctions.
Biometric locks are an excellent addition to your home’s security, but regular maintenance of these features is essential for smooth operation.
4. Monitor Activity Logs for Suspicious Behaviour
Most smart locks provide detailed activity logs via their companion apps. These logs can show who accessed the lock, when, and whether any failed entry attempts were made. Monitoring these logs regularly can give you insights into potential security threats.
Why Monitoring is Important:
- Spotting unauthorised attempts: If someone tries and fails to enter the correct code multiple times, this could indicate an attempted breach.
- Keeping track of access: If you’ve provided access to multiple people, monitoring logs help ensure they use the lock appropriately.
- Immediate alerts: Some locks send real-time alerts if multiple failed attempts to enter a code, warning you early of possible tampering.
Best Practices for Monitoring:
- Set up alerts: Configure your lock’s app to send push notifications or email alerts in case of unusual activity.
- Review logs periodically: Make it a habit to check the lock’s activity log, especially if you’ve shared access codes with others.
- Take action: If you notice anything unusual, such as unfamiliar attempts to access your lock, immediately change your codes and consider reviewing your overall security settings.
Activity logs can serve as an early warning system, helping you respond quickly to suspicious behaviour and safeguard your property.
5. Protect Against Power Failures and Low Batteries
While smart locks offer advanced security features, they still rely on power, typically from batteries. Ensuring your lock doesn’t lose power unexpectedly is vital to maintaining security and avoiding potential lockouts.
Why Power Management is Critical:
- Lockouts: If your lock’s battery dies, you could be locked out of your home without a backup method.
- Security risks: A low battery may prevent the lock from engaging properly, leaving your home vulnerable to unauthorised entry.
- Delayed response: Low power can also affect the lock’s ability to communicate with connected devices, such as your smartphone or home assistant.
Battery Management Tips:
- Monitor battery life: Most smart locks provide low-battery warnings through their app or on the lock itself. Pay attention to these alerts and replace batteries as needed.
- Use quality batteries: Invest in high-quality batteries, preferably lithium, which last longer and perform better in extreme temperatures.
- Have a backup plan: Many smart locks include a physical keyhole for manual entry, while others can be powered temporarily with a 9V battery if the main battery dies. Always know your lock’s backup method and keep it accessible.
Being proactive about your smart lock’s battery management will help you avoid the inconvenience of lockouts and ensure your home remains secure.
Additional Tips for Smart Lock Safety
Beyond the five key areas we’ve discussed, there are additional ways further to enhance the safety of your digital door lock system:
Use Two-Factor Authentication (2FA)
If your smart lock’s app supports it, enable two-factor authentication to add an extra layer of security to your lock. This means that even if someone gets access to your app credentials, they’ll still need a second form of authentication to make changes or control the lock.
Avoid Sharing Your App Login Information
Never share your app login information with others. If you need to grant someone temporary access to your home, use your lock’s guest access feature or generate a temporary code rather than giving them full control through the app.
Regularly Inspect the Physical Components
Even though smart locks are largely digital, the mechanical components like the deadbolt and latch still require care. Check for wear and tear regularly and ensure everything is properly aligned. If you notice the door isn’t closing smoothly, make adjustments or call a professional.
Don’t Forget About Wi-Fi Security
If your smart lock is connected to your home’s Wi-Fi, ensure your network is secure. Use strong passwords and regularly update your router’s firmware to protect against unauthorised access to your smart home devices.
