What happens if the smart lock battery dies?
All smart locks in our list have emergency power options. Most support 9V battery backup - just touch a 9V battery to the external power terminals to unlock. Some models (Mygate, Atomberg) support USB power bank charging. Additionally, every lock includes a physical key for emergency access. Smart locks typically warn you 2-3 weeks before batteries die with low battery alerts.
Can smart locks be hacked?
Modern smart locks use AES-128 or AES-256 encryption - the same used by banks. Bluetooth smart locks (all in our list) are inherently safer than WiFi locks since they can only be accessed within 10-15m range. The main vulnerability is weak PINs (like 1234). Use 6+ digit random PINs, enable unauthorized freeze after wrong attempts, and use PIN decoy features when available. Physical forced entry remains the bigger realistic threat.
Do smart locks work during power cuts?
Yes! Smart locks run on batteries (typically 4-8 AA batteries), not mains electricity. Power cuts don't affect them at all. Battery life typically lasts 8-12 months depending on usage. The Bluetooth connection from your phone also works without WiFi or mobile data.
Can I install a smart lock myself?
If you're replacing an existing mortise lock with the same standard dimensions, DIY installation is possible. However, we strongly recommend professional installation for: precise fitting ensuring no security gaps, correct door alignment, proper battery compartment sealing against moisture, and warranty validity (some brands require authorized installation). LAVNA, Atomberg, and Godrej offer free installation - take advantage of it.
Which smart lock is best for rental properties?
For rentals, prioritize: low cost (LAVNA 3-Way at ₹3,134), OTP access to change codes between tenants (LAVNA 6-Way at ₹5,189), and easy reinstallation if you move. Avoid premium locks for rentals. The LAVNA 6-Way offers the best combination of OTP access, free installation, and affordable pricing for rental situations.
Why don't smart locks have WiFi in India?
WiFi smart locks exist but are rare in India due to: higher cost (₹25,000+), reliance on stable internet (problematic in many areas), faster battery drain, and security concerns about cloud-connected locks. Bluetooth locks offer excellent functionality without these drawbacks. For most Indian homes, Bluetooth is the smarter choice. WiFi is only needed if you must unlock remotely from another city.
Are smart locks weatherproof for Indian conditions?
Most smart locks are designed for indoor use on main doors protected by corridors or overhangs. For fully outdoor exposed installations, check IP rating (IP54 or higher recommended). Fingerprint sensors may have issues in extreme humidity - keep them dry. For outdoor gates, consider dedicated outdoor-rated locks or add weather protection. All locks in our list are suitable for typical Indian main door installations.
How do I share access with family members?
Multiple options: (1) Register their fingerprints on the lock (50-100 capacity), (2) Share the PIN code, (3) Add their phone as authorized user in the app, (4) Generate temporary OTP codes for visitors. For permanent family members, fingerprint registration is most convenient. For temporary guests (delivery, maid), OTP is ideal since codes expire automatically.
