Lock out of nest

[Lindaxpham]

So recently my router blew out. The internet company came and replaced old router with a new one. This changed my login name and password internet connection. My NEST thermostat 3gen had a pin connected to the old router that no longer works. I tried to log into my nest app to unlock my thermostat but I can’t view my nest from app to unlock nest either. I’m completely locked out of my own nest thermostat 3gen. Any one else have or had this problem? Need help unlocking my thermostat since pin and nest app doesn’t work.

If you can't control it using the app anymore, 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.

@Lindaxpham When I had to have my ISP provided router replaced, I logged onto the new router and changed the SSID and password to the same as it was on my old router so i didn't have to switch over all my devices to a new network.

Another option you could try (not something I've done but it may work) would be to use your phone/tablet to setup a wifi hotspot with the same SSID and password as the wifi on your old router. The thermostat would then connect directly to your phone and you should then be able to use the nest app to enter the pin.
