Frequently Asked Questions

Why does my August lock firmware update keep failing?
The most common causes are low battery (below 20%), poor Bluetooth connection, app issues, or interruptions during the update process. Ensure fresh batteries, stay within 3 feet of the lock, and keep the app open during updates.
How long does an August lock firmware update take?
August lock firmware updates typically take 5-10 minutes to complete. The process should not be interrupted, so ensure good Bluetooth connection and sufficient battery before starting.
Can I use my August lock if firmware update failed?
A failed firmware update may leave your lock temporarily unresponsive or in update mode. You may need to perform a manual reset and re-add the lock to the app to restore normal functionality.
What type of batteries work best for August lock updates?
Use 4 AA lithium batteries for best performance during firmware updates. Lithium batteries provide more consistent power and last longer than alkaline batteries, reducing the chance of update failures.
