FAQs
Are smart locks as secure as traditional locks?
Yes, and often more so. Many smart locks are built on top of Grade 1 or Grade 2 deadbolts and add features like activity tracking, auto-locking, and encryption. However, security also depends on your home network’s integrity.
Can smart locks be hacked?
While no device is 100% immune, most reputable smart locks use end-to-end encryption and two-factor authentication. Regular firmware updates and strong passwords reduce risk significantly.
Will a smart lock work with my existing door?
Most smart locks are compatible with standard deadbolt setups. Some retrofit models (like August) install over your existing lock, while others require a full replacement.
What happens if the power goes out or the battery dies?
Smart locks run on batteries and don’t rely on your home’s electricity. If the battery dies, many models allow manual key access or emergency charging via USB.
Can I still use a regular key?
Many smart locks retain the traditional key option. Others (like some Yale or Level models) offer completely key-free solutions for added security.
How many people can access a smart lock?
It varies by model, but most allow you to create multiple digital keys or PIN codes—perfect for family, friends, and even pet sitters.
Can I control my lock remotely?
Yes—if your smart lock has Wi-Fi or is paired with a smart home hub. You can lock/unlock from anywhere, view access logs, and get real-time alerts.
Is professional installation necessary?
Most smart locks are designed for DIY installation using basic tools. However, if replacing a complicated deadbolt or setting up wiring, a professional may be helpful.
Are smart locks weather-resistant?
Most exterior smart locks are rated for outdoor use and withstand rain, cold, and dust. Always check for an IP rating (e.g., IP65) if it’s going on an exposed door.
Do smart locks work with rental properties or Airbnb?
Yes. Some models allow time-limited access codes, perfect for short-term rentals. Brands like August and Schlage offer integrations with platforms like Airbnb for automatic code generation.
