August Lock: Stiff Mechanism Repair Guide for Canadian... | digitalhomefaults.org

Technical Background:

The August Lock's mechanism relies on a DC motor driving a series of gears to actuate the deadbolt. The motor's performance is highly sensitive to voltage. Cold temperatures increase the internal resistance of the lithium battery pack, reducing available voltage and torque. Mechanical friction within the gear train is also exacerbated by low temperatures due to lubricant viscosity changes. The August lock communicates using Bluetooth and Wi-Fi (bridge required) for remote control and status updates.

Symptoms:

Resistance felt when manually turning the August Lock. Audible grinding noise emanating from the lock motor. Delayed or failed locking/unlocking via the August app. Increased battery drain during cold weather operation. No LED error codes initially, but potential for red flashing LED after repeated failures.

Possible Causes:

Low battery voltage due to cold weather impedance increase (-20°C to -40°C).
Lubricant within the lock mechanism becoming viscous in cold temperatures.
Door frame warping due to seasonal temperature fluctuations causing binding on the deadbolt.
Strike plate misalignments creating excessive friction on the deadbolt.
Internal gear wear or damage within the August Lock mechanism.
RF interference from other 2.4GHz devices (Wi-Fi routers, cordless phones).

Solution:

1

Replace batteries with fresh lithium AA batteries. Lithium batteries perform better in cold environments compared to alkaline.
2

Verify door frame alignment. Check for any visible warping or shifting. Adjust strike plate if necessary to ensure smooth deadbolt operation. A small shim behind the strike plate might alleviate binding.
3

Apply a small amount of silicone-based lubricant to the deadbolt and strike plate to reduce friction. Avoid petroleum-based lubricants, as they can stiffen in cold temperatures.
4

Check the August app for firmware updates and install them. Ensure the Wi-Fi bridge, if used, is also up to date. Poor firmware or Bridge version can affect motor commands.
5

Measure battery voltage under load using a multimeter. Remove the battery cover, insert the batteries and without triggering the lock, read voltage across battery terminals; a reading below 4.5V indicates low voltage which requires battery replacement.
6

Check local Wi-Fi signal strength (RSSI) near the lock location using a Wi-Fi analyzer app on a smartphone. If RSSI is below -70 dBm, consider relocating the Wi-Fi bridge closer to the lock to improve connectivity. Check compatibility with Bell Giga Hub 2.4GHz band and disable band steering if required.

Safety Warning:

Always ensure that access to your property is maintained through alternative means (e.g., physical keys) in case of smart lock failure. Regularly test manual operation of the lock. Back up your August Lock credentials and settings in case of device replacement or reset. Be aware of potential lithium battery fire risks. Do not attempt to disassemble the August Lock beyond battery replacement. If you suspect physical tampering, contact a security professional.

Prevention:

- Replace batteries annually before the onset of winter. Consider using high-capacity lithium batteries. - Regularly check door frame alignment and adjust strike plate as needed. - Periodically lubricate the deadbolt and strike plate with silicone-based lubricant. - Keep the August Lock firmware updated to the latest version via the August app. - Monitor battery level in the August app and replace batteries proactively.

Expert Tip:

If the August Lock is unresponsive, try removing and reinserting the batteries to perform a hard reset. This can sometimes clear minor software glitches and restore functionality. Note that after a hard reset, the lock may need to be re-paired with the August app and Wi-Fi bridge.

Frequently Asked Questions

•What type of batteries should I use in my August lock for optimal performance in cold weather?

Lithium AA batteries are recommended for August locks in cold Canadian winters. They have a wider operating temperature range and maintain voltage better than alkaline batteries at low temperatures.

•How can I improve the Wi-Fi signal strength to my August lock's bridge?

Try moving the Wi-Fi bridge closer to the August lock. Also, reduce interference from other devices by keeping the bridge away from microwaves and other electronics. Consider using a Wi-Fi extender if necessary.

•What are the signs that my August lock is experiencing mechanical binding due to door frame warping?

You may notice increased resistance when manually turning the lock, the lock motor struggling to actuate the deadbolt, and unusual noises such as grinding or squeaking. Visually inspect the door frame and strike plate for misalignment.
