Clé de récupération BitLocker : comment retrouver votre clé à 48 chiffres
A blue recovery screen does not automatically mean your files are gone. To find your Clé de récupération BitLocker, start with the Microsoft account used to set up the PC, your work or school account, or a saved backup. The task is to locate the correct existing BitLocker recovery key and match it to the locked drive.
If a usable record remains on an accessible Windows computer, Magic Recovery Key provides another way to search for it. Our BitLocker recovery resource center covers related situations. Start with the route below that matches your device’s current state.

Before You Start: Preserve Access and Record the Key ID
Write down the recovery key ID shown on the locked screen. It identifies the BitLocker recovery key record you need; it is not the 48-digit unlock code.
Keep the drive intact while searching. Do not format it, reset Windows, clear the TPM, or make random firmware changes to remove the prompt. Those actions are not substitutes for finding the right key. If Windows still starts, back up important files and recovery information before changing security settings.
Keep any recovered key private. Avoid posting a screenshot that exposes it in a public support thread.
Where Should You Look for Your BitLocker Recovery Key First?
Choose the route that fits what is accessible now. A locked startup screen and a working Windows desktop require different approaches.
Current situation | First route | If that does not work |
Personal PC stops at the recovery screen | Check the Microsoft account used during setup from another device | Check other setup accounts and saved backups |
Work or school device is locked | Check the organization account or contact IT | Ask IT to search its recovery records |
A USB drive, printout, or backup may contain the key | Read the saved record on an accessible device | Match its identifier to the recovery screen |
Windows still starts and the volume is unlocked | Back up the key or inspect existing protectors | Search available records with a suitable utility |
Only an encrypted, locked disk is available | Search account and external backup records first | Ask support to assess the available evidence before trying more scans |
Qu'est-ce qu'une clé de récupération BitLocker ?
A Clé de récupération BitLocker is the 48-digit number Windows can request when a protected drive cannot unlock normally. In technical documentation, this numeric code is also called a recovery password. It is commonly displayed in eight groups of six digits.
It differs from a Windows sign-in password, a PIN, and a Windows activation key. The recovery key ID is different too: it helps identify the matching record but cannot unlock the disk by itself. See Microsoft’s BitLocker recovery overview for the underlying recovery options.
Firmware, TPM, boot configuration, or hardware changes can trigger recovery. Moving a protected disk into another computer can also change its unlock conditions. A recovery prompt therefore does not, by itself, establish that files were deleted or that the disk has failed.
How to Find Your BitLocker Recovery Key in a Microsoft Account
Meilleur pour : A personal computer whose BitLocker recovery key was backed up to a Microsoft account.
Use a phone or another computer if the affected PC cannot start:
- Open the official Microsoft recovery keys page.
- Sign in with the account used when the PC was set up.
- Locate a record whose key ID matches the recovery screen.
- Enter its associated 48-digit number on the locked PC.
If the list is empty, check whether another person originally configured the device. An older personal account may also be relevant. For instructions and account-related notes, use Microsoft’s find your recovery key guide.
Résultat attendu : The matching BitLocker recovery key is accepted and the drive becomes accessible. If no matching record appears, continue with organization records or saved copies. Repeatedly signing into the same empty account will not reveal a backup stored elsewhere.
Retrieve Your BitLocker Recovery Key from a Work or School Account
Meilleur pour : Computers enrolled in, or previously connected to, an organization.
- Visiter Microsoft My Account from another device.
- Sign in with the relevant work or school account.
- Ouvrir Dispositifs and select the affected computer.
- Rechercher View BitLocker Keys, if your organization allows it.
- Match the identifier before using the displayed code.
If self-service access is unavailable, contact IT. Provide the device name and recovery key ID so the administrator can search the appropriate records. Microsoft’s recovery process documentation explains recovery through Microsoft Entra ID and Active Directory.
A missing self-service button does not prove that no backup exists. Permissions and backup configuration matter. For a secondhand business computer, the previous organization may need to resolve the issue through its authorized support process.
Find a BitLocker Recovery Key on USB Storage or in Saved Files
Meilleur pour : Someone who saved or printed recovery information when encryption was configured.
Check removable storage, printed setup records, and accessible backups. If a USB drive contains a text copy, read it on another working computer. Do not rely on a copy stored only inside the volume that is currently locked.
For an efficient manual search:
- List the USB drives, backup folders, and document archives used during setup.
- Search accessible locations for filenames containing BitLocker ou Clé de recouvrement.
- Open likely text records and compare their identifiers.
- Use the matching 48-digit code, then store a protected backup separately.
Record which locations you have checked. That prevents repeat searches and gives a support technician a useful history if you need help later.
An old backup may contain a key for a different volume or an earlier protector. A similar filename is not enough to establish that it belongs to the current prompt. Microsoft’s backup guidance explains supported ways to preserve recovery information.
Check an Existing BitLocker Recovery Key While Windows Is Accessible
Meilleur pour : An authorized administrator using an accessible Windows installation with the relevant BitLocker tools available.
If Windows still starts and the protected volume is unlocked, inspect its existing recovery protector before a future lockout. Open Invite de commandes en tant qu'administrateur et exécutez :
- manage-bde -protectors -get C: -type RecoveryPassword
Remplacer C : with the correct volume letter. Look for the numerical recovery password and its identifier. Microsoft documents this command in the manage-bde protectors reference.
This command inspects configured protectors. It does not create a missing backup or defeat encryption. Running a command against a locked volume should not be presented as a dependable way to extract its secret.
If no recovery password appears, check the selected volume and ask an administrator to review its configuration. Do not delete protectors or turn off protection simply to make the output change. Back up any valid recovery information through the supported management options.
Search for a BitLocker Recovery Key with Magic Recovery Key
Meilleur pour : Users who have checked account backups and want a guided search for available key information on a working Windows computer.
Magic Recovery Key includes a dedicated BitLocker search function. It can be useful when manually checking available records becomes difficult. Its role in this workflow is to help locate recovery information, not generate a universal unlock code.

How to Search for a Stored BitLocker Recovery Key
Les official user guide describes this process:
1. Install and launch Magic Recovery Key on a working Windows computer.
2. Ouvrir Clé de récupération BitLocker.
3. Select the disk to check and click Recherche.
4. Review any returned key and identifier.
5. Copy or save the relevant result securely.
Compare the returned identifier with the locked screen before trying the code. Then verify the outcome by opening the drive and checking important files. A displayed BitLocker recovery key alone does not establish that the particular locked volume has been recovered.
Check Suitability Before Scanning
A different working computer does not automatically contain the missing key. Likewise, connecting an encrypted disk elsewhere does not make its contents readable. If only a locked system disk remains, ask Amagicsoft support whether the available setup is supported before assuming a scan can retrieve its key.
If the search returns nothing, note what was scanned and revisit unexamined account or backup locations. Repeating the same scan without a change in available information may not help. Review the product’s current license terms before purchase; do not assume full retrieval is free.
Next step: Utilisation Magic Recovery Key when the available computer and records fit this search workflow.
Found a 48-Digit BitLocker Recovery Key? Verify It First
Searches such as “48 digit recovery key to unlock drive” usually lead to the same practical question: does this particular code belong to this particular drive?
Use this checklist:
- Record match: Compare the saved key ID with the recovery screen.
- Correct credential: Use the complete 48-digit number, not a PIN or activation key.
- Correct volume: Distinguish the startup drive from separate data volumes.
- Actual access: Confirm that Windows starts or the intended drive opens.
- Usable files: Open important documents and copy essential data to a backup.
If the code is rejected, recheck the record and the typed digits before changing the device. Multiple keys in an account are not interchangeable. For recurring prompts after a successful unlock, investigate the trigger with IT or device support rather than repeatedly resetting security settings.
Que faire si vous ne trouvez pas la clé de récupération BitLocker ?
Make a short inventory of the evidence still available: setup accounts, organizational ownership, USB backups, printed records, accessible computers, and any recent device changes. Use that inventory to identify the next untested route.
There is no universal recovery code. A key-finding utility cannot promise to reconstruct a secret that was never saved or is no longer accessible. Ordinary file recovery software also does not replace the credentials needed to decrypt a locked volume.
If the data matters, preserve the disk while seeking qualified advice. Do not treat resetting or reinstalling Windows as a recovery method for the encrypted files. Microsoft states that its support team cannot recreate a lost key and warns that resetting the device removes files.
Keep Recovery Information Available After Unlocking
Once access is restored, back up important files and save recovery information separately from the protected device. Keep a device name and key identifier with the backup so future matching is easier.
For a managed computer, follow your organization’s storage policy. Review the cause of the prompt before firmware or hardware work continues. A key that works today should be backed up and protected, rather than left only in an open application window.
Conclusion
Trouver le bon Clé de récupération BitLocker starts with identifying the device state and checking the most likely backup location. Match the key ID, use the associated code, and confirm that the intended files are accessible.
If account and manual searches fail but suitable records remain available, Magic Recovery Key offers an additional search route. For related guidance, visit our BitLocker recovery resource center. Preserve the drive while searching, and back up the recovered information once access returns.
