Frequently Asked Questions
What is the best smart lock for 2026?
The August Wi-Fi Smart Lock is our top pick for 2026, offering the best combination of features, reliability, and smart home integration. It maintains your existing deadbolt while adding smart functionality and includes built-in Wi-Fi connectivity.
Are smart locks secure and reliable?
Yes, quality smart locks from brands like August, Yale, and Schlage offer the same or better security than traditional locks. They use AES-256 encryption, undergo regular security audits, and provide additional features like access logs, temporary codes, and remote monitoring.
Do smart locks work without internet?
Most smart locks function locally without internet, allowing keypad entry, key access, and basic operation. However, remote control, notifications, smart home integration, and app access require an internet connection.
How long do smart lock batteries last?
Battery life varies by model and usage. Basic models typically last 8-12 months, while feature-rich locks like the August Wi-Fi last 4-6 months. Low battery warnings typically provide 2-4 weeks notice before complete depletion.
Can smart locks be hacked?
While no technology is 100% secure, modern smart locks use bank-level encryption and have excellent security records. The risk of digital attacks is generally much lower than traditional lock picking or key copying vulnerabilities.
Do I need to replace my entire deadbolt?
Not necessarily. Retrofit smart locks like the August Wi-Fi attach to your existing deadbolt, requiring no changes to your door or keys. Full replacement locks offer more features but require removing your current deadbolt entirely.
