August Lock: Bolt Not Moving Troubleshooting - Smart Home | digitalhomefaults.org

Technical Background:

The August Lock uses a motorized drive to engage/disengage a standard deadbolt. The system relies on rotational force from the motor, transferred via a gearbox, to move the bolt. RF communication (typically Bluetooth/Wi-Fi) controls the lock. Power is provided by internal batteries (Lithium-Ion/Alkaline). Cold weather impacts battery impedance, reducing available current to the motor. Mechanical stress from door frame warping can increase friction on the bolt.

Symptoms:

Bolt fails to extend or retract despite audible motor operation. Observed LED error code: Solid red. App reports: "Motor jammed" or "Bolt obstructed". Manual operation also restricted; key turns but bolt doesn't shift.

Possible Causes:

Low battery voltage, insufficient to drive the motor under load, particularly in temperatures below -10°C.
Mechanical binding between the bolt and strike plate due to door frame misalignment caused by seasonal temperature changes.
Gearbox damage within the lock mechanism, preventing torque transfer from the motor to the bolt.
Obstructed bolt path: debris or foreign object interfering with bolt movement.
Incorrect deadbolt cylinder system: excessive friction between the key cylinder and the bolt mechanism.
RF interference causing delayed or corrupted commands to the lock (2.4GHz interference from Rogers Ignite/Bell Giga Hub).

Solution:

1

Replace batteries with fresh Lithium-Ion batteries (rated for -20°C operation). Monitor voltage under load (locking/unlocking). Expected voltage: >4.5V.
2

Inspect the strike plate and door frame alignment. Loosen strike plate screws, reposition for optimal bolt clearance. Use a file to remove any burrs or obstructions. Lubricate the bolt with graphite powder.
3

Manually extend/retract the deadbolt (using the key) to assess mechanical resistance. If resistance is high, consult a locksmith to adjust the deadbolt cylinder.
4

Check for obstructions in the bolt path. Remove the lock housing to visually inspect the bolt mechanism. Clear any debris.
5

Check Wi-Fi signal strength (RSSI) near the lock using a Wi-Fi analyzer app. Ensure RSSI is above -70 dBm. Reposition the router or add a Wi-Fi extender to improve signal strength.
6

Perform a factory reset of the August lock (consult the August support website for specific instructions). Re-pair the lock with the August app.
7

If using a C-wire, confirm consistent 24VAC power with a multimeter.

Safety Warning:

Do not attempt to disassemble the lock mechanism beyond removing the battery compartment. Improper disassembly can damage the lock and void the warranty. Lithium batteries can pose a fire hazard if mishandled. Dispose of used batteries properly according to local regulations. Ensure secure password management and enable two-factor authentication on your August account.

Prevention:

- Replace batteries annually before the onset of winter. Use Lithium-Ion batteries for optimal cold-weather performance. - Periodically inspect and lubricate the bolt mechanism. - Monitor door frame alignment for seasonal warping. Adjust strike plate as needed. - Keep the lock firmware updated to the latest version via the August app. - Assign a static IP address to the August Lock to reduce network connectivity issues on Bell Giga Hub or Rogers Ignite.

Expert Tip:

If the motor runs but the bolt doesn't move, try manually assisting the bolt while the motor is running. This can sometimes help overcome a minor mechanical obstruction and allow the lock to complete its cycle. Check the battery contacts for corrosion and clean them with isopropyl alcohol if necessary.

Frequently Asked Questions

•How do I check the battery level on my August Lock?

Open the August app and navigate to the lock's settings. The battery level will be displayed as a percentage.

•What type of batteries should I use in my August Lock for Canadian winters?

Use Lithium-Ion batteries specifically rated for cold-weather performance. These batteries maintain voltage better in freezing temperatures compared to alkaline batteries.

•How do I realign my strike plate if my door frame is warped?

Loosen the strike plate screws. Use shims (thin pieces of wood or plastic) behind the strike plate to adjust its position. Tighten the screws once the strike plate is aligned with the bolt.
