I forgot my pin

If you can still control your thermostat in the Nest app, unlock it and change the PIN using the app:
Lock and unlock your Nest thermostat - Google Nest Help

If your thermostat isn't connected to Wifi or the app, you'll need to reset it using a computer.

1. Connect the Nest Thermostat display via USB to a computer.
   
   
2. Verify that the Nest Thermostat mounts (appears as an attached drive icon).

• If the Nest drive will not mount: Restart the thermostat and the computer.
• If the Nest drive still won't mount: Connect another device to the cable to see if it appears as an installed device.
• If it doesn't appear, use a different cable/port/computer.

If the Nest drive is successfully showing up on your computer, can you see a technicalinfo.PLIST file? If you get this far let me know and I'll ask a community specialist to assist with next steps, as these can't be shared publicly in the community.

Hello there,

I wanted to stop by and see how I could help, as this thread has multiple posts to avoid confusion.

Thank you for sharing the steps, @David_K.

@K1keiwanito, I'm checking in to see if you had a chance to connect your thermostat to a computer and were able to locate the folder. This is for us to move forward on unlocking your thermostat. Please let us know how it goes.

Best regards,

Mark
