If your thermostat is still connected to Wi-Fi and you can see it in the Nest app or Home app, you can unlock and reset the PIN using the app:

Lock and unlock your Nest thermostat - Google Nest Help

If you can't control it using the app anymore, you'll need to reset it using a computer.

Connect the Nest Thermostat display via USB to a computer.
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.

If it's still connecting to Wi-Fi and you can manage it via the Nest app or Google Home app, you can change the PIN in the app. Go to the help article below and refer to the "How to change the lock code" section.
