Tamper Alert - Red Exclamation Mark on App

DesertCanuck — Fri, 13 Feb 2026 02:56:59 GMT

We had a battery failure; I replaced them - lokc powered up. It works with the outside keypad, thumb toggle etc; BUT on the app it shows a Red Exclamation mark - that just will not go away. Any suggestions - like a reset etc; I really want to avoid removing the product from my account and re-entering it - it is such a hassle getting it to go back online.

Hi @DesertCanuck,

Thank you for posting in the community. I understand that after replacing the batteries of your lock, you’re receiving a tamper alert with a red exclamation mark in the app even though you’re able to manually lock and unlock it. I also see that you want to avoid removing the device from the app since it can be a bit difficult to add it back to the app. No worries, I’m happy to assist you. To get started, here are some questions for you:

What is the exact model of your lock? (You can share a picture of the device if you aren't sure).
What app are you using to control your lock? Is it the Google Home app or the Nest app?
Could you please share a screenshot of the message with the red exclamation mark you’re seeing?

A quick tip: Sometimes a tamper alert is triggered if the battery cover isn't fully seated or if the mounting plate was slightly nudged during the battery change. You might want to double-check that the cover is snapped firmly into place.

I’ll be waiting for your response.

Regards,

Daniel
