With four convenient unlock methods and a rugged weatherproof build, it's the smartest way to manage key access from anywhere in the world.

Frequently Asked Questions

Q: Does this smart key lock box work without a smartphone?

A: Yes! While the Tuya, Smart Life, or TTLock app adds powerful remote management features, you can also unlock the key box using a fingerprint, PIN code, or IC card — all without a smartphone. The app is optional but greatly enhances functionality.

Q: Do I need a gateway/bridge for WiFi remote access?

A: Bluetooth connectivity works out of the box within 10 meters of your phone. For remote WiFi access from anywhere, a gateway bridge is required: the G2 Gateway for TTLock users and the M1 Gateway for Tuya/Smart Life users (sold separately).

Q: Is this key safe box truly weatherproof for outdoor use?

A: Yes. The K5F model is rated IP65 (dust-tight and water-jet resistant) and the K3F model is rated IP54 (splash-proof), making both suitable for year-round outdoor wall mounting. The zinc alloy and stainless steel construction also resists tampering attempts.

Q: How many fingerprints and passwords can be stored?

A: The lock box supports up to 150 password groups with 6 to 16-digit codes, multiple fingerprint profiles, and IC cards — giving you the flexibility to share access with family members, guests, or service providers while maintaining full control via the app.

Q: What happens if the batteries run out?

A: This key safe box features an emergency external power input, so you can temporarily supply power using an external battery pack to unlock it and replace the internal AAA batteries without being locked out.
