Article Summary:
Here are some troubleshooting steps you can take if Nest Protect doesn’t power on immediately after the battery tab has been removed.

When the Nest Protect battery tab is pulled out, the light ring should glow blue and welcome you by saying, “Hi, from Nest.“

If you don’t see a blue light or hear the welcome message after removing the battery tab, the batteries may need to be re-seated. To fix the problem, you will need to remove the batteries and clean out any pieces of the battery tab that are left in the battery tray.

Here’s how:

Remove the batteries in each battery tray, make sure no pieces of battery tab remain, and reseat the batteries in the proper orientation.

Press down on each battery to make sure that both ends are touching the Nest Protect contacts.

Remove the two screws on the back of Nest Protect with a small Phillips screwdriver and take off the cover.

Note: You will need to push the spring-loaded battery stays out of the way to get the third battery into each tray.

Once the batteries are reinstalled, reattach the battery door by sliding it into the tabs located on the opposite side from the batteries and replacing the screws.

At this point, your Nest Protect should turn on and the light ring should glow blue. If not, please Contact Nest Support.
