Question: What are the safety instructions for the Smart Internal Door Lock with Fingerprint?
Answer:
For indoor use only — avoid moisture, rain, and direct sunlight.
Fits 35–55mm doors with 60mm or 70mm backset.
Only works with single-cylinder lock setups.
Recharge before first use (up to 3.5 hours with a 5V USB-C source).
Use the Connect SmartHome app to register fingerprints.
Unregistered fingerprints won't work once setup is complete.
Store mechanical keys safely for backup access.
Keep the USB-C charger nearby for emergency power.
Wipe only with a dry, soft cloth — no water or chemicals.
