Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Multi-Authentication Security: Combines fingerprint scanning, numeric keypad entry, RFID card access, and a physical key backup for fail-safe entry.
  • Smart Connectivity: Controlled via Tuya and TTLock apps for remote management, real-time activity alerts, and cloud-based storage of access codes.
  • Waterproof Design (IP65): Ensures reliable performance in outdoor and high-moisture environments.
  • Anti-Peep Code Entry: Reduces code theft risks with randomized input patterns.
  • Physical Key Backup: A U-shaped key provides emergency access in case of electronic failure.

Key features

  • 1. Corrosion-Resistant Zinc Alloy Construction

    • With a corrosion-resistant zinc alloy body and IP65 waterproof rating, you can withstand outdoor elements longer than traditional plastic-based locks.*

  • 2. Multi-Mode Touchscreen Interface with Anti-Peep Code

    • With a multi-program touchscreen interface supporting fingerprint scanning, numeric keypad input, and anti-peep code technology, you can manage access for multiple users more securely than single-method systems.*

  • 3. EN 1634-1 Fire Resistance & Cloud-Based Security

    • With EN 1634-1 fire resistance certification and cloud-based password storage, you can ensure uninterrupted security during emergencies and remote management compared to offline-only locks.*

  • 4. Biometric + Physical Key Fail-Safe Access

    • Combining biometric authentication (fingerprint/card) with a physical U-shaped key backup, you can maintain access in all scenarios, unlike locks lacking fail-safe mechanisms.*

  • 5. Globally Certified Safety & Eco-Friendly Design

    • Certified to CE, EN 1634-1, RoHS, and FCC standards, this lock meets stricter global safety and environmental regulations than non-certified alternatives.*
