Does the lock work with the Tuya or SmartLife app?
Yes. The M5 is fully compatible with Tuya Smart and SmartLife apps via Bluetooth.
Remote control requires a Tuya WiFi gateway (sold separately).
What happens if the battery runs out?
The lock will warn you in advance when the battery is low.
If the battery is completely drained, you can use:
A mechanical key, or
A Type-C emergency power supply to unlock.
Is the lock suitable for indoor or outdoor use?
The lock body is typically designed for indoor or semi-outdoor use depending on your door type.
(Check the model details for waterproof rating if your door is fully exposed.)
Can I create guest passwords?
Yes. You can generate temporary, one-time, or time-limited PIN codes for guests, cleaners, or service providers through the app.
How many fingerprints can be stored?
The M5 usually supports up to 100 fingerprints (varies slightly by model version).
Does the lock require WiFi to work?
No. The lock works offline with fingerprints, passwords, IC cards, and Bluetooth.
WiFi is only needed if you want remote unlocking or real-time notifications, which requires a Tuya gateway.
How long does the battery last?
With normal use, the battery typically lasts 3–6 months, depending on usage frequency.
