Are Smart Door Locks Safe from Hacking? Here’s What You Need to Know
As smart locks become more popular, one common concern holds people back: can they be hacked? While no device is 100 percent immune to threats, modern smart locks are designed with robust security features to prevent unauthorized access.
Common Misconceptions
“Anyone can hack it from outside.”
Not true. Most smart locks use encrypted communication over Bluetooth or Wi-Fi, and cannot be accessed without the correct app authentication.
“Fingerprint data can be stolen.”
Biometric data is stored securely inside the device, not transmitted over the internet.
How Smart Locks Prevent Hacking
• AES Encryption: High-end models use AES 128 or 256-bit encryption—the same level used in banking.
• Two-Factor Authentication: Apps often require OTP verification or biometric unlock.
• Random PIN Entry: Some locks allow random digits to be added before or after the actual code, preventing shoulder surfing.
• Tamper Alerts: If someone tries to break the lock physically, you receive a notification instantly.
Best Practices to Stay Safe
• Use a strong, unique PIN or password
• Avoid sharing credentials on public platforms
• Enable app alerts for every unlock/lock event
• Change temporary guest codes frequently
• Keep the firmware updated
