How to reset the PIN on thermostat

[Kaps17]

Hi, I’ve lost my Nest connection to my thermostat and I don’t remember the PIN.  How can I hard reset the thermostat so I can unlock it in order to reconnect it to the Nest app?

If your thermostat isn't connecting to Wi-Fi and/or is no longer in the app so you can change/reset the pin, follow these steps:

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.

Thanks.  I ended up remembering my PIN and so I was able to unlock and reconnect it to the Nest App.  Thanks!
