Nest 2nd Gen Can't Add to App Need "Key"

[nos92]

I'm trying to setup a 2nd gen that we moved to a  new house.  It is asking for a "key" to add the device but I can not find it and the stat says it's connected to the Nest app.  Any help?  Thanks.

If the thermostat says it's already connected to the Nest app, that means the previous owner did not reset it before leaving. Try these steps:

1. Press your thermostat and go to Settings > Reset > All Settings (Turn the ring to select the options).
2. Download the Nest app on your phone or tablet.
3. On the Nest app home screen, tap the Settings cog.
4. Tap Add product. The app will switch to a camera view to scan the thermostat’s QR code.
5. To get the QR code, press your thermostat and go to Settings.
6. Turn the ring to select Nest app and press to open it.
7. Select QR code. Your thermostat will show you a unique QR code to scan with the app.

nos92, how's your thermostat now? Have you managed to find the entry key?
