Smart Locks Explained: Convenience Meets Security
Published: July 26, 2026·By the DoorSecurityGroup Installation & Review Team

Smart locks are highly secure when chosen correctly. Look for models with an ANSI Grade 1 or 2 rating, robust encryption (like AES 128-bit or higher), and features like two-factor authentication. A smart lock offers superior convenience without compromising physical security if properly installed.
What is a Smart Lock?
A smart lock is an electromechanical lock that receives instructions to lock and unlock from an authorized device using a wireless protocol (Wi-Fi, Bluetooth, Z-Wave, or Zigbee). They offer keyless entry via smartphone apps, keypads, or even voice commands.
Security Considerations for Smart Locks
As security experts, we often get asked if smart locks are "hackable." While anything connected to the internet carries some risk, reputable smart locks employ stringent security measures.
Physical Security (ANSI Grading)
The smart lock is only as good as its physical deadbolt.
- Actionable Advice: Ensure the smart lock you purchase is certified as ANSI Grade 1 (highest security) or Grade 2. This ensures the physical hardware can withstand brute-force attacks.
Digital Security
- Actionable Advice: Always enable Two-Factor Authentication (2FA) on your smart lock app account. Keep the lock's firmware updated, and use a strong, unique password for your home Wi-Fi network.
Power Outages and Batteries
- Actionable Advice: Choose a smart lock that features a physical key override or backup power terminals (like a 9V battery jumpstart) in case the internal batteries die completely.
Benefits of Smart Locks
- Keyless Entry: No more fumbling for keys or hiding spares under the doormat.
- Access Control: Create temporary access codes for guests, dog walkers, or contractors, and revoke them anytime.
- Activity Logs: Keep track of who enters and leaves your home, and at what time.
- Remote Locking: Forgot to lock the door? Lock it from anywhere using your smartphone.
Conclusion
Smart locks are a excellent addition to a modern home security setup. By choosing a high-quality model from a reputable brand and following digital security best practices, you can enjoy unprecedented convenience and peace of mind.
