Problem Description

August calibration fails when the deadbolt binds or the adapter is not seated correctly. This guide checks door alignment, adapter fit, and app calibration steps so the motor can complete a full lock cycle.

Why This Happens in Real Homes

August calibration fails when the deadbolt binds or the adapter is not seated correctly. This guide checks door alignment, adapter fit, and app calibration steps so the motor can complete a full lock cycle. In day-to-day use, this usually looks like Calibration fails in the app; Lock stops mid-turn; Motor clicks but bolt does not move.

Most cases trace back to Deadbolt binding in strike plate; Adapter not seated on tailpiece; Mounting plate misaligned. The fix works best when you go step by step instead of changing multiple settings at once.

A practical order for this issue is: Check Manual Locking -> Reseat the Adapter -> Square the Mounting Plate -> Run App Calibration. After each step, test the exact behavior that was failing so you can confirm what actually solved it.

Symptoms

  • Calibration fails in the app
  • Lock stops mid-turn
  • Motor clicks but bolt does not move

Step-by-Step Solution

1

Check Manual Locking

Lock and unlock the deadbolt by hand several times. If it feels tight or catches, adjust the strike plate before proceeding.

2

Reseat the Adapter

Remove the lock body and ensure the adapter fits the tailpiece snugly. Use the correct adapter size for your deadbolt model.

3

Square the Mounting Plate

Reinstall the mounting plate so it sits flat and centered. A crooked plate causes the motor to bind during calibration.

4

Run App Calibration

Open the August app, start calibration, and keep the door fully closed. Do not touch the lock during the motor cycle.

5

Test Multiple Cycles

Run lock and unlock three times in the app to confirm the motor completes the full range without errors.

Quick Solutions

Align the strike plate for smooth lock
Reseat adapter and mounting plate
Run calibration with door closed
Replace batteries with fresh AAs
Confirm handedness in the app
Re-run calibration after adjustments

Still having issues? This is usually the deeper cause below.

This usually happens right after a router reboot or ISP change — the device rejoins the network but drops its cloud session silently.

Pro Tip

If the deadbolt is stiff, sand or realign the strike plate before forcing the lock to calibrate.

  • Door not fully closed during calibration
  • Batteries low
