Zerokey smart locks feature military-grade AES-256 encryption and multiple layers of security. Our biometric recognition systems (3D facial, palm vein, fingerprint) use advanced anti-spoofing technology and are virtually impossible to bypass. All data is securely encrypted and stored locally on the device.

All Zerokey smart locks include a built-in rechargeable battery backup that can last up to 12 months on a single charge. You'll receive low battery notifications through the app. Additionally, every lock features a hidden emergency key slot as a last resort to ensure you're never locked out.

Yes! Zerokey locks are designed for easy DIY installation and typically take less than 30 minutes with just a screwdriver. Each lock comes with detailed instructions and video tutorials. For those who prefer professional installation, we offer certified installation services in major cities across India.

The core biometric and keypad functions of Zerokey locks work without Wi-Fi. However, for remote access, real-time alerts, smart home integration, and automatic updates, Wi-Fi connectivity is required. The lock will store access logs locally when offline and sync when reconnected.

All Zerokey smart locks come with a comprehensive 2-year warranty covering manufacturing defects and hardware issues. We also offer 30-day money-back guarantee, free software updates, and 24/7 customer support. Premium models include extended warranty options.
