Weiser Aura Lock: Troubleshooting Green/Red Flashing Light

Fix Weiser Aura smart lock flashing green and red. Diagnose battery issues, RF interference, and mechanical problems. Expert tips for Canadian homes.

Frequently Asked Questions

•How do I check the battery voltage on my Weiser Aura?

The Weiser app typically displays the battery level. If not, you can use a multimeter to measure the voltage directly at the battery terminals after removing the battery pack. Expect around 6V for a fresh set of AA batteries.

•What kind of lubricant should I use on the bolt and strike plate?

Use a silicone-based lubricant. Avoid petroleum-based lubricants, as they can damage the lock's internal components over time.

•My lock is connected to a smart home hub. Could that be causing the problem?

While less common, interference from other smart home devices operating on the 2.4 GHz band (Wi-Fi, Bluetooth) can sometimes disrupt the Aura's communication. Try temporarily disabling other nearby devices to see if the issue resolves.

Technical Recommendation:

A rapid three-tap sequence on the interior deadbolt lever can sometimes force a recalibration of the locking mechanism. This can bypass minor mechanical binding issues temporarily. Check the lock's firmware version in the app – older versions are often linked to this error.

How It Works:

The Weiser Aura utilizes a Bluetooth Low Energy (BLE) connection for communication with the mobile app and local control. The flashing green/red sequence typically indicates a fault in the lock's internal logic, often related to power management (battery voltage), motor drive circuit malfunction, or communication errors during the locking/unlocking process. Mechanical binding of the bolt can also trigger the error due to excessive current draw.

Recommended Action:

1

Replace the batteries with fresh, high-quality alkaline batteries (Energizer or Duracell recommended). Note the expiry date. Ensure correct polarity.
2

Temporarily move the Weiser Aura closer to the Bluetooth device to rule out RF interference. Minimize obstructions (walls, metal objects).
3

Perform a manual calibration cycle: Remove the battery pack, press and hold the program button for 10 seconds, reinsert the battery pack.
4

Check the door frame alignment and strike plate. Ensure the bolt moves freely without binding. Lubricate the bolt and strike plate with silicone-based lubricant.
5

If possible, attempt a firmware update via the Weiser app. Ensure a stable Bluetooth connection and sufficient battery power.
6

Power cycle the lock: Remove the battery pack for 60 seconds, then reinsert.
7

If the issue persists, contact Weiser support for warranty assistance, referencing the flashing green/red error code.

Common Causes:

Low battery voltage, especially exacerbated by cold temperatures (-20°C to -40°C) causing increased internal resistance.
RF interference on the 2.4GHz band, disrupting communication with the app during critical operations.
Mechanical binding of the bolt due to door frame warping from seasonal temperature changes, increasing motor load and current draw.
Corrupted firmware or incomplete over-the-air (OTA) update.
Faulty motor drive circuit unable to provide sufficient torque to move the bolt.
Fingerprint sensor malfunction causing invalid unlock attempts and triggering the error state.

What to Look For:

The Weiser Aura smart lock exhibits a flashing green light followed by a flashing red light. This visual pattern repeats. The lock may be unresponsive to user input (keypad, app control) and/or exhibit intermittent locking/unlocking behaviour. This is commonly reported during periods of extreme cold.

Preventative Care:

Replace batteries annually before the onset of winter to mitigate cold-weather performance degradation.
Regularly check the door frame alignment and strike plate, especially after significant temperature fluctuations.
Enable automatic firmware updates in the Weiser app to ensure the lock is running the latest software.
Clean the fingerprint sensor regularly with a soft, dry cloth to maintain optimal performance.
Monitor battery voltage levels through the app and replace before they drop below 20%.
