Bitlocker key requested on the boot, but I don’t have any key

Hi Yann, 

First of all, is this device is set up under your Microsoft account, or does the business own it? 

If it is business, then their IT will be able to provide you a BitLocker key from Entra Admin. 

Or you can simply get the keys from  https://account.microsoft.com/devices/recoverykey

More things to check are temporarily disabling any active VPN connection, then opening an incognito or private browsing window in your web browser, and going to the above-mentioned link and getting the key from there.

If you are still having issues, connect your device to another Wi-Fi network, such as a mobile hotspot network, and then see if you can view the BitLocker recovery key.

Please let me know if this helps.

Unfortunately, if the key was never backed up anywhere and you don't have a printed or saved copy, the drive's contents are not recoverable — that's by design; BitLocker's whole purpose is that AES-encrypted data is inaccessible without the key or the original TPM/PIN state. No support tier, Microsoft or otherwise, can bypass this, and no legitimate data recovery service can break the encryption itself (some will claim they can try, but for BitLocker specifically that's essentially never true unless there's a weak, guessable password involved).

At that point your realistic options are:

Keep digging through every account/device/file location above (many people find it eventually)

If the data isn't critical, do a clean install of Windows on the drive (this wipes it) and use it going forward — ideally with recovery key backup enabled and verified this time

If the data is precious and irreplaceable, it may be worth pausing and not doing anything else to the drive until you've exhausted every account check, in case a professional recovery specialist ever does have a legitimate avenue (rare, but not worth foreclosing prematurely)

Hi Yann1,

If BitLocker is asking for the recovery key, it's because Windows detected a change that requires recovery verification (TPM, firmware/BIOS, Secure Boot, hardware changes, etc.). Unfortunately, the recovery key is the only supported way to unlock the drive. Since you've already checked your Microsoft account, I'd also check a few other places:

• Your organization's Azure AD (Entra ID) or Active Directory, if this was ever a work-managed device.
• A USB drive, printed copy, or another Microsoft account where the key may have been saved.
• Any backup or password manager where you might have stored it.

If the recovery key can't be found anywhere, there's no supported method to bypass BitLocker encryption. The only remaining option is to erase the drive and reinstall Windows, which will unfortunately result in data loss.
