airtag alerts others when family member uses my keys

Hi kellek,

​Thank you for using the Apple Support Communities. We see you have a concern about alerts from an AirTag, and we're happy to see if we can help. The information below is from the resource titled What to do if you get an alert that an AirTag or Find My network accessory is with you:

"If you see an "Item Detected Near You" message

If you see this message on your iPhone, iPad, or iPod touch running iOS or iPadOS 14.5 or later, an AirTag or Find My network accessory that has been separated from the person who registered it is traveling with you, and the owner might be able to see its location. It's possible that the AirTag or Find My network accessory might be attached to an item you're borrowing. Follow these steps to turn off these notifications or disable the AirTag or Find My network accessory: 

1. Tap the message.
2. Tap Continue. If you need help finding the AirTag or Find My network accessory, tap Play Sound.
3. If the AirTag or Find My network accessory is attached to an item you're borrowing, you can tap Pause Safety Alerts to turn off "Items Detected" notifications for one day. 

• • If you're borrowing an AirTag from a member of your Family Sharing group, you can turn off Safety Alerts for one day or indefinitely. 
  • You can tap Learn About This AirTag to see its serial number if the owner marked it as lost. 

1. To disable the AirTag or Find My network accessory and stop sharing your location, tap Instructions to Disable and follow the onscreen steps. If you feel your safety is at risk, contact your local law enforcement who can work with Apple. You might need to provide the AirTag, Find My network accessory, or the device's serial number."

Let us know if disabling Safety Alerts helps. Take care.
