Hi Celia,
Thanks for posting to the Community. If you're locked out of your Surface Pro 11 and can't use Face Recognition, your PIN, or password, you'll need to create a USB recovery drive to reset it. Before doing it, if you have important files that needs to be backed up, you may need it to be serviced by a third paty repair shop. If you want to proceed, here is a simple guide I made for you.
Step 1: Prepare a USB Recovery Drive. You need a working Windows PC and a USB flash drive, at least 16GB. Next, Go the the Microsoft Surface recovery image site. https://www.microsoft.com/en-us/software-download/windows11arm64
Sign in with your Microsoft account and enter your Surface’s serial number to download the recovery image.
Set Up the USB Drive:
-Format the USB drive to FAT32.
-Extract the recovery image files directly onto the root of the USB drive.
Step 2: Boot From USB
-Shut down your Surface completely > Insert the USB recovery drive > Press and hold the Volume Down button while tapping the Power button > Release the Volume Down button when you see the Surface logo.
Step 3: Reset Your Device
-Once in the recovery environment, choose your language and keyboard layout. Go to Troubleshoot > Recover from a Drive. Select Remove Everything and Fully Clean the Drive.
This will wipe your Surface and restore it to factory settings, allowing you to set it up again.
I hope this helps. Let me know if you need more guide by replying to this thread.
