If fingerprint unlock isn’t working, start with the 3 most common causes: sensor, finger, battery.
Step-by-step fixes
- Clean the sensor: Use a microfiber cloth (no harsh chemicals).
- Re-register fingerprints: Add the same finger 2–3 times from slightly different angles.
- Try another finger: Some fingers scan better than others.
- Replace batteries: Weak batteries can reduce sensor reliability.
- Check permissions: Ensure the fingerprint is assigned to the correct user access level.
Pro tips for better fingerprint success
- Use the “pad” of your finger, not the tip.
- Press consistently (not too light, not too hard).
- If hands are wet/dry, wipe and try again.
Still stuck? Remove and re-add the fingerprint in the AUSLOCK App, then test again.
