Frequently Asked Questions
Q: Does the XSDTS F18 smart door lock work without Wi-Fi?
A: Yes! Even without a Wi-Fi connection, you can still unlock the door using the fingerprint scanner, PIN keypad, IC card, or mechanical key. Wi-Fi and Bluetooth are required only for Tuya App remote access and unlock history syncing.
Q: What door types is this smart lock compatible with?
A: The XSDTS F18 is compatible with a wide range of door types, including wooden doors, steel doors, brass doors, stainless steel doors, and double doors. It fits doors between 40–70 mm thick and uses a standard 5050 mortise cutout.
Q: What happens if the batteries die — am I locked out?
A: No. The F18 features an emergency external power input port on the front panel. Simply hold a portable power bank or 9V battery to the contacts to temporarily power the lock and gain entry. The low-battery warning system also gives you advance notice before power runs out.
Q: How many fingerprints and users can be registered?
A: The F18 supports multiple user profiles, each with their own fingerprint, PIN, or card credentials. You can manage and review all user access records through the Tuya App or directly on the lock itself.
Q: Is the XSDTS F18 smart lock easy to install?
A: Installation requires drilling and is designed to replace a standard door lock using a 5050 mortise. The package includes all necessary components, and the lock's direction-reversible handle makes it suitable for both left- and right-opening doors. Basic DIY experience is recommended.
