###   

The Battery Insights feature provides clear, accurate information about your lock’s battery health so you know when to replace your batteries, how long they are expected to last, and what to do if your lock stops responding. This guide covers battery states, notifications, settings, replacement steps, and emergency access options for key-free models.

  

  

#### **1\. What are the Different Battery States in Yale Access Battery Insights?**

  

Battery Insights reports one of four states based on information sent directly from your lock. Each state explains your current battery condition and whether action is needed.

  

* * *

## Sufficient

Your batteries are in good condition. You may also see an estimated timeframe for how long the batteries are expected to last based on typical usage.

## Low

Your batteries are nearing depletion. We recommend replacing them soon to avoid interruptions in daily use.

## Critically Low

Your lock may stop responding at any moment. Replace your batteries immediately to avoid being locked out.

## Check Battery Status / Unknown

The app is unable to determine the battery level. This may occur when the lock is offline, newly reset or installed, or unable to report. Continue using your lock as you normally would, once your lock collects enough data it will display the remaining battery life.

## **2\. Battery Prediction**

  

Learn how Battery Insights estimates how long your batteries are expected to last, why predictions may change over time, and how your usage and connection type affect accuracy.

  

* * *

## How does Battery Insights Calculate Battery Life?

Battery Insights uses a machine-learning model that looks at how you use your lock along with real battery readings to estimate how long your batteries are expected to last. The estimate becomes more accurate over time as the system learns from your lock’s behavior.

![](https://cdn.prod2.kustomerhostedcontent.com/media/5f6cab56313fd9001af97923/61ac5fc72795c447e91ba289bbc541d6.png)

## Why Does My Battery Life Estimate Change Over Time?

Battery predictions may shift at first because the system is still collecting data. This is normal and improves as your lock reports more battery information.

## How Manual vs. App Use Affects Battery Reporting

Manual operation (turning the thumbturn) does **not always send** a battery update.  
Using the **Yale Home app** to lock or unlock periodically helps keep your battery percentage accurate.

## How Wi-Fi, Bridge, and Bluetooth Connections Affect Battery Accuracy

*   **Wi-Fi or Connect Bridge:** Best experience (your lock reports battery status automatically and more frequently).  
      
    
*   **Bluetooth-only locks:** Need app-initiated lock/unlock actions to refresh battery percentage.  
      
    

## How to Get the Most Accurate Battery Readings

It is recommended to use the app from time to time, keep your lock connected (via Yale Wi-Fi module or Bridge), and allow the system time to learn your usage pattern.

## **3\. When Will I Receive Battery Notifications and Where Can I See Them?**

  

Understand when battery notifications are sent, what triggers them, and where you can view battery alerts and history in the Yale Home app.

  

* * *

## What Triggers Battery Notifications

You will receive a notification when:

*   The lock reports a **Low** battery state

*   The lock reports a **Critically Low** battery state

*   Your battery state changes while you are away from home (wifi enabled locks only)

## What's New About Battery Notifications

*   Notifications are sent less frequently to avoid unnecessary repeats.  
      
    
*   Alerts include the correct battery type and a preview of replacement steps.  
      
    
*   Battery events appear in your **Activity Feed**, providing a clear history of past alerts and battery behavior.>
    
      
    

##   

  

## **4\. How Do I Manage Battery Notification Settings**

  

Battery notifications depend on both your in-app settings and your phone’s notification permissions. To receive battery alerts, notifications must be enabled in both places.

  

Use the steps below to turn battery alerts on or off in the Yale Home app and confirm your device settings allow notifications.

  

* * *

## How to Manage Battery Alerts in the Yale Home App

Open the **Yale Home app** and select **your home** from the **Keychain**  
  

*   Tap the **Setting** icon on the right bottom corner  
    ![](https://cdn.prod2.kustomerhostedcontent.com/media/5f6cab56313fd9001af97923/75f47ff3afca2236be708f2205f126e6.png)
    
*   Select **Lock Settings** and find **Battery Notifications**.  
    ![](https://cdn.prod2.kustomerhostedcontent.com/media/5f6cab56313fd9001af97923/240a09dcab2bdfeabd14de18c1de804e.png)
    
*   Toggle on preferred **Battery Alerts** type On/Off.

When enabled, you will receive Low and Critically Low battery alerts.  
 When disabled, alerts will not be sent, but battery state will still update in the app.

2.  Remove the old AA batteries.
3.  Insert **4 new AA alkaline batteries**, following the polarity markings.

4.  Reinstall the interior cover.
5.  The lock will automatically power on and update its battery level in the app.  
      
    
    *   **Note:** The system may not update the new battery status immediately. Use your lock as you normally would while the system collects updated information about the lock battery status.
    
      
    
      
    

##   

  

## **6\. How Does 9V Emergency Access Work on Key-Free Yale Locks? (Key-Free Models Only)**

  

If your lock’s batteries are fully drained **and your lock does NOT have a physical keyway**, you can temporarily power it using a **standard 9V battery**. This provides enough power to unlock the door and replace the internal AA batteries. 

  

**Important**: 9V emergency power is not available on keyed models. If your lock has a key cylinder, use your physical key instead.

  

* * *

## How To Use 9V Emergency Power to Unlock Your Door

1.  Hold a 9V battery firmly against the emergency terminals on the bottom of the lock.  
    ![](https://cdn.prod2.kustomerhostedcontent.com/media/5f6cab56313fd9001af97923/80d499c7d0368ab5818c129ba8c9d58b.png)
    
2.  The lock will turn on temporarily.  
      
    
3.  Use your entry code, app, or fingerprint (if supported) to unlock the door.  
      
    
4.  Replace the AA batteries immediately once inside.  
      
    

### **Notes**

*   The 9V battery does **not** charge the lock; it provides temporary power only.  
      
    
*   Keep a 9V battery accessible if you own a key-free model.
    
      
    

##   

  

## **7\. How Can I Troubleshoot Battery Reporting or Notification Issues?**

  

Find solutions for common issues like incorrect battery readings or missing battery notifications.

  

* * *

## If the Battery Percentage Looks Incorrect

*   Ensure you are using **alkaline** AA batteries.  
      
    
*   Lock and unlock the door a few times to refresh the reading.  
      
    
*   If the lock was offline recently, allow a moment for the estimate to update.
    

## If You're Not Receiving Battery Notifications

*   Confirm **Battery Alerts** are turned on in the Yale Home app.  
      
    
*   Ensure **Allow Notifications** is enabled in device settings.  
      
    
*   Verify your email address, if using email alerts.  
      
    
*   Check your **Activity Feed** for battery-related events.

* * *

## Recommended Battery Type 

*   4× AA alkaline batteries (standard, non-rechargeable)  
      
    

## Battery Types to Avoid

*   Rechargeable batteries (NiMH)  
      
    
*   Lithium or lithium-ion batteries

**Note:** Using the correct battery type ensures optimal performance and accurate reporting in Battery Insights.

  

##   

  

## **9\. Frequently Asked Questions**

  

Quick answers to common questions about battery alerts, estimates, and emergency access.

  

* * *

## How often will I receive battery notifications?

Only when your battery level reaches Low or Critically Low, or when the state changes significantly. The system avoids sending repeated alerts and not more than 3 times for each battery alert type.

## Why does the app show an estimated remaining life?

Battery Insights uses real-time lock data to estimate how long the batteries are expected to last. This helps you plan ahead for replacements.

## Does the 9V emergency method work if the lock is completely unresponsive

Yes, on key-free models. The emergency terminals provide enough temporary power for you to unlock the door and replace your AA batteries.

## Can I disable battery notifications?

Yes. You can turn off Battery Alerts in the Yale Home app or disable notifications at the device level.
