Need to enter keycode

Try these in order:

1. On the sign-in or recovery screen, select the Accessibility icon and open On-Screen Keyboard. Use the mouse to enter the code.
2. If this is the normal Windows sign-in screen, select Sign-in options and switch to the password option instead of PIN. Sign in with the account password, then set up the PIN later from Settings > Accounts > Sign-in options.
3. If this is a BitLocker recovery screen and the keyboard is not responding, try a basic wired USB keyboard connected directly to the PC. Wireless or Bluetooth keyboards may not work at that stage.
4. If the device uses MBAM Self-Service Portal, enter at least the first 8 digits of the 32-digit Recovery KeyId, select a reason, choose Get Key, and then enter the returned 48-digit recovery key on the BitLocker recovery screen. This requires that the portal was configured by IT and that the user previously signed in physically to that computer at least once.
5. If sign-in still fails, use Microsoft’s sign-in helper or contact support. Support agents cannot send password reset links or change account details.
