Fast, versatile unlocking

Open your door in under 0.3 seconds using the fingerprint sensor, or choose from app control, keypad entry, a physical key, or voice commands via your preferred assistant. The fingerprint recognition improves with use, delivering quicker entry for trusted family members.

Power you can rely on

Powered by a 10,000 mAh rechargeable battery, the lock can run up to about 14 months between charges depending on usage. A low‑battery alert appears at 20% and a power‑save mode can extend endurance by weeks. In emergencies, a portable charger can provide unlock power but cannot recharge the battery or transfer data.

Remote power considerations aside, the lock prioritizes local access and secure operation even when connectivity is limited.

Remote access and management

Control and monitor from Apple Home or other supported hubs. You can set access permissions, view real‑time notifications, review event logs, and unlock remotely when appropriate, giving you flexible control for busy households.

Install ease and coverage

Installation is designed to be drill‑free and quick, commonly completed in about 15 minutes. The product is backed by 18 months of electronic protection and 36 months of mechanical coverage, plus responsive 24/7 support for setup questions or troubleshooting.

Everyday use scenarios

Imagine returning with bags in hand, a guest arriving, or a caretaker visiting. You can grant temporary access, share codes, or lock and monitor entry from anywhere. Logs and alerts help you stay informed without intruding on daily life.

• Hands‑free entry when your hands are full
• Temporary codes or app‑based access for visitors
• Clear activity history for transparency and control

These benefits depend on your setup and daily routines, offering possibilities rather than guarantees for every situation.
