To get the entry key for your third generation Nest thermostat, you typically need to access it through the Nest app or your Google Account. If you have it set up, open the app, go to settings, and look for the "Entry Key" option under the device settings. If you've lost access, the entry key reset process may require you to follow specific steps in the app. Please check your app for the exact navigation to find this feature.
