Hello Mj Mj3,

thank you for posting on the Microsoft Community Forums.

Here are a few steps you can try to resolve this issue:

1. Double-Check Password and Recovery Key: EDouble-check that you are entering the correct recovery key. Sometimes, a simple typo can cause the key to be rejected.
2. Case Sensitivity: Remember that passwords are case-sensitive. Make sure your Caps Lock key is not on while entering the password.
3. Use BitLocker Management Tool:
   • Open File Explorer.
   • Right-click on the locked drive and select "Unlock Drive".
   • Enter your password or paste the recovery key there.
4. Use Command Prompt:
   • Open Command Prompt as an administrator.
   • Type the following command to unlock the drive using the recovery key (replace X with the drive letter and YourRecoveryKey with your actual recovery key):
   manage-bde -unlock X: -RecoveryPasswordYourRecoveryKey
   • If successful, you can then remove BitLocker encryption if desired by using:
   manage-bde -off X:
5. Check for Typographical Errors: If you have a printed or written copy of your recovery key, check for typographical errors. Sometimes characters like 0 (zero) and O (capital o) or 1 (one) and I (capital i) can be confused.
6. Verify Drive Letter: Ensure that you are trying to unlock the correct drive letter, as reinstalling Windows can sometimes change drive letters.

Best regards,
