Key Features
- No-Drill, Punch-Free Installation: Single-sided indoor installation with zero visible hardware on the exterior. Setup is straightforward with no permanent modifications to your door.
- Ultra-Fast Unlocking: Simply swipe your IC card outdoors and the lock opens in just 0.5 seconds — smooth, silent, and instant.

- Bluetooth Remote Control: Unlock from up to ~8 metres via Bluetooth through the app. Pair with an optional gateway (sold separately) for true internet-based remote access from anywhere.
- Smart Magnetic Auto-Locking: The lock tongue senses the built-in magnetic stone when the door closes and automatically latches — no manual locking required.
- Low-Battery Protection: When voltage drops below 4.6V, the voice system alerts you to replace the batteries, and the lock tongue retracts automatically so you're never locked out.
- Reversible Handle Direction: Fits both left- and right-handed door configurations.
- Wide Compatibility: Designed for non-metal indoor doors (home, office, rental, etc.) with a thickness of up to 60mm.
