Bitlocker Key ID on machine mismatch to Key ID on MS account

I just did a reinstall of Win11 my laptop, and a key was generated Key ID A841723. When I

restarted machine, had a PIN error. I restarted in safe mode using the KEY on my account that matched the ID, drive unlocked and I chose F5 (reboot with networking). Boot screen appeared with the same PIN error, also noticed no WIFI. Tried reset with the same Key but got an invalid key message. I noticed a new key ID that began with the same A841723 with a 24 alpha-numeric suffix; this new ID is not on my account. I'm guessing the system generated this new key while not connected to wifi. Is there anyway to unlock the drive at this point?

    Hello

    Thank you for posting in Q&A forum.

    Here are some steps you can:

    1. Check All Accounts:

    Ensure you've checked all Microsoft accounts that might have been used on the laptop. Sometimes, the recovery key might be stored under a different account.

    1. Use the BitLocker Recovery Key:

    • Go to the Microsoft Recovery Key page) and verify if any of the listed keys match the new Key ID.

    • If you find a matching key, use it to unlock the drive.

    1. BitLocker Repair Tool:

    • You can use the BitLocker Repair Tool to attempt to recover data from the encrypted drive. Open Command Prompt as an administrator and run:

    • repair-bde C: X: -rp <Your 48-digit recovery password>

    Replace C: with the drive letter of the encrypted drive and X: with the drive letter where you want to save the recovered data.

    I hope the information above is helpful.

    If you have any questions or concerns, please feel free to let us know.

    Best Regards,
