Troubleshoot when nothing happens after removing 1st gen Nest Protect's battery tab

This article is for 1st gen Nest Protect. Check which Nest Protect you have.

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:

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

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

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

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

3. 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.
