Frequently Asked Questions

Q: How many fingerprints can the XSDTS ZSF3 smart door lock store?

A: The XSDTS ZSF3 Tuya smart door lock can store up to 150 fingerprint profiles, making it perfect for households, small offices, or rental properties with multiple users. Fingerprint recognition achieves 99.8% accuracy and unlocks in under 1 second.

Q: Does this smart door lock work without Wi-Fi?

For remote app control via the Tuya platform, your smartphone needs an internet connection. A gateway accessory (sold separately) can extend full remote access.

Q: What happens if the batteries run out?

A: The XSDTS ZSF3 features a built-in low-battery alert that notifies you well in advance. In an emergency, a USB charging port on the lock allows you to temporarily power it with a power bank so you can unlock and replace the batteries. 4 × AAA batteries are included in the box.

Q: Is this lock suitable for apartment doors?

A: Yes, provided your door is between 35–70 mm thick and is a standard mortise-compatible door type (steel, wood, brass, or stainless steel). The reversible handle fits both left- and right-handed doors. English-language installation instructions are included, and no wiring is required.

Q: Can I share access with guests temporarily?

A: Absolutely. Through the Tuya smart home app (available on iOS and Android), you can generate and share temporary access codes or assign time-limited permissions for guests, housekeepers, or visitors — and revoke access instantly when it is no longer needed.
