Hi @Niz1,

Thanks for reaching out to the Google Nest Community. I'm sorry to hear you're having trouble with your Nest Thermostat missing the entry key. I appreciate you completing those troubleshooting steps. I'm glad to assist you.

To provide the best assistance, could you please tell me:

• Which model of Nest Thermostat do you have? 

• When did you purchase the Nest Thermostat?

I look forward to your response.

Hi @Niz1,

Thank you for your reply and for providing the helpful details about your Nest Thermostat. I'm glad to share more information.

Since October 25, 2025, the first- and second-generation Nest Learning Thermostats will disconnect from the Nest App and Google Assistant. They will also lose access to clients like Assistant and Alexa. Remote services like HVAC monitoring, energy programs, and Nest Protect safety shutoff integration will no longer function.

Devices will continue to:

• Run local features like HVAC control, UI, and Auto-Schedule.
• Fetch weather data and product information to prevent performance degradation on systems.

Feel free to keep posting if you have more questions.

Regards,

Gabriela
