Yale Assure Locks that are being used with the Yale Access or August apps must be calibrated properly for optimal performance. 

**IMPORTANT**: The instructions below are for the following locks: YRD 216/226/256, YRL 216/226 and require DoorSense to be installed.

If you are trying to rehand your lock that **_does not_** have DoorSense, please refer to this article: [How to Fix a Jammed Deadbolt](https://support.shopyalehome.com/how-to-fix-a-jammed-deadbolt-rJ4jCHuIS).

  

During the initial setup, follow the steps to ensure the lock is calibrated according to your door. Recalibration is necessary if the lock stops operating as it should. For example, if the lock circle displays as green when the door is actually locked, recalibration is needed and should fix the issue.

  

Before proceeding with the recalibration steps, remove the lock's battery cover and remove and reinsert one battery. Next, while you are within Bluetooth range of your lock, follow the steps to recalibrate:

1.  Open the Yale Access App and navigate to the affected lock
2.  Select **Lock Settings**
3.  Scroll to and tap on **Calibrate Lock**
4.  Follow in-app instructions to recalibrate

This should correct lock performance issues due to miscalibration.
