Frequently Asked Questions
Are smart locks secure enough for home protection?
Modern smart locks often exceed traditional lock security when properly installed and configured. Look for BHMA Grade 1 certification, strong encryption (AES 256-bit), and locks from reputable security companies. The convenience features shouldn’t compromise the fundamental security function.
What happens if the battery dies or Wi-Fi goes out?
Most smart locks include multiple backup access methods. Physical key backups are common, and many models accept emergency power from a 9V battery applied to external terminals. Wi-Fi outages typically don’t affect local smartphone or keypad access.
Can smart locks be hacked?
While no technology is 100% secure, modern smart locks use strong encryption and security protocols. Choose locks with regular firmware updates, avoid older models with known vulnerabilities, and follow security best practices like using unique access codes and monitoring activity logs.
How difficult is smart lock installation?
Retrofit models typically install in 15-30 minutes with basic tools. Full deadbolt replacement requires more work but is manageable for most homeowners with basic DIY skills. Professional installation is available and recommended for complex installations or if you’re uncomfortable with the process.
Do smart locks work during power outages?
Yes, smart locks operate on battery power and function normally during power outages. Local features like keypad and smartphone access continue working. Remote access may be limited if your internet router is also affected by the outage.
How often should I change access codes?
Change access codes when someone who knew them no longer needs access (former employees, house guests, service providers). For high-security situations, consider rotating codes monthly. Most smart locks make this process simple through their mobile apps.
