Bitlocker not unlocking despite using the recovery key

Question

My Dell xps13 laptop died on me; I removed the ssd drive to recover my data on another computer. It asks me to unlock the drive using the recovery key which I copy from my Microsoft account. But it keeps showing recovery error saying the key isn’t correct. I kept several times to type it manually as well, same result. How can I overcome this?

Hi GD,

Welcome to the Microsoft Q&A forum.

When an SSD encrypted with BitLocker is removed from its original laptop and connected to another computer, Windows may rely entirely on the recovery key to unlock it. Please check your Microsoft account to ensure that you are using the correct recovery key as multiple keys can be associated with a single device.

With the right recovery key, you can consider the 2 options below to proceed:

1, Use repair-bde to extract data

• Connect the SSD to a working Windows PC.
• Connect a second empty drive (same size or larger).
• Open Command Prompt as Administrator.
• Run the repair-bde command using your 48‑digit recovery key to copy data to the empty drive: repair-bde E: F: -rp YOUR-48-DIGIT-RECOVERY-KEY

2, Try unlocking via Command Prompt

• Open Command Prompt as Administrator.
• Use manage-bde -status to identify the drive letter.
• Attempt to unlock using manage-bde -unlock with your recovery key: manage-bde -unlock E: -rp YOUR-RECOVERY-KEY
• If successful, copy your files immediately to another drive.

If none of the above methods succeed, it usually indicates the encrypted volume metadata can no longer be read. In that case, BitLocker’s design prevents further access, and data recovery would not be possible without a prior backup.

Answer 2

If your BitLocker-encrypted drive is not unlocking despite using the recovery key from your Microsoft account, there are a few steps you can take to troubleshoot the issue:

1. Verify the Recovery Key: Ensure that you are using the correct recovery key. Sometimes, multiple keys can be associated with a single device, especially if you have made changes to the BitLocker settings. Check your Microsoft account to confirm that you are using the right one.
2. Check for Typing Errors: When entering the recovery key manually, ensure that you are typing it correctly. The recovery key is a 48-digit number, and even a small mistake can prevent access.
3. Use the Recovery Key ID: If you have access to the recovery key ID, you can use it to verify that you are retrieving the correct recovery password. This can help ensure that the key you are using corresponds to the specific drive.
4. Try Another Computer: If possible, try connecting the SSD to a different computer and attempt to unlock it there. Sometimes, the issue may be related to the specific hardware or configuration of the original computer.
5. BitLocker Repair Tool: If you suspect that the drive may be corrupted, consider using the BitLocker Repair Tool (repair-bde.exe). This tool can help recover data from severely damaged drives, but it requires the BitLocker key package and the corresponding recovery password.
6. Contact Support: If none of the above steps work, consider reaching out to Microsoft support or Dell support for further assistance. They may have additional tools or methods to help you recover your data.

Remember to keep backups of your recovery keys in secure locations to avoid similar issues in the future.
