7. Nlekọta
Ngbanwe batrị:
The lock requires 4 AA batteries (not included). When the battery level is low, the lock will provide an audible or visual alert. Replace all four batteries simultaneously with new, high-quality alkaline batteries to ensure optimal performance and prevent issues.
Nhicha:
Clean the lock's exterior with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish and electronic components. Regularly wipe the fingerprint sensor to ensure accurate readings.
8. Nchọpụta nsogbu
Issue: Cannot unlock from outside when deadlocked from inside.
Nkọwa: The Yamiry Smart Door Lock features a deadlocking system that, when engaged from the inside (by rotating the interior knob), prevents all external unlocking methods, including fingerprint, keypad, key fob, and even the physical key. This is a security feature designed to provide maximum privacy and prevent forced entry.
Ngwọta: This is not a malfunction but an intended security feature. To unlock the door from the outside, the deadlocking mechanism must first be disengaged from the inside. If you frequently use the interior deadlocking feature and require external access, ensure someone inside can disengage it, or consider adjusting your usage habits. The manufacturer provides a method to disable this internal deadlocking switch if this feature is not desired; refer to the detailed User Guide for instructions on how to do this.

Figure 6: Understanding the deadlocking security feature.
Issue: Fingerprint sensor is unreliable.
Ngwọta: Ensure your finger is clean and dry when attempting to use the sensor. Re-register your fingerprints, trying different angles and pressures during the registration process to capture a more comprehensive scan. Regularly clean the sensor surface with a soft, dry cloth.
Issue: Keypad not responding.
Ngwọta: Check the battery level. Low batteries can affect keypad responsiveness. Ensure the keypad is clean and free from debris. If the issue persists, try resetting the lock (refer to the User Guide for reset instructions).
