With the 3rd generation August Smart Lock and later, you still have Auto-Lock capability, meaning your lock can automatically lock itself after a specified time period. Now, with the included DoorSense™ technology, which informs you whether your door is open or closed, you can program your Smart Lock to lock automatically as soon as it detects that your door is closed.

  

To set up Instant/Intelligent Auto Lock you must have DoorSense™ installed and calibrated. You can find DoorSense™ Installation instructions under your Lock Settings, or refer to the [DoorSense™ Installation guide](https://support.august.com/what-is-doorsensetm-Hk4vL1A_z).

  

Once DoorSense™ is enabled and calibrated, navigate to **Lock Settings**, and select Auto-Lock.

Toggle the Auto-Lock button to turn it on.

By default, Auto-Lock is set to turn on via a timer. If this setting is selected, you can specify an amount of time before your door is auto-locked. Note, that with DoorSense™ enabled, the Auto-Lock will not engage if the door state is identified as Open. Once the door state changes from Open to Closed, the timer will begin the countdown and the door will auto-lock once the time has expired.

To change the setting to ‘Instant’, select ‘On A Timer’ and change the setting to ‘Instant’. This guarantees that every time your door state changes from Open to Closed, the August Smart Lock will Auto-Lock, instantly.

When Instant Auto Lock is enabled, the option for Re-Lock Timing becomes available. This timer is used to re-lock your August Smart Lock if the lock is unlocked, but the door never opens. After the specified time period, the lock automatically auto-locks.
