"The Recovery Key You Entered Is Incorrect"? You're Probably Using the Wrong One of Several

You typed your 48-digit BitLocker key but the screen says “The recovery key you entered is incorrect” (or wrong key), or you have several saved keys and don’t know which to use.

Why: A drive can have more than one recovery password over its life — BitLocker was turned off and on, the key was rotated, or protectors were added or removed — and each one has its own Key ID. Only the key whose ID matches the one shown on the recovery screen will unlock that drive. An “incorrect key” message almost always means you entered a real-but-wrong key from a different volume, device, or an older printout. This is a matching problem, not a typo (though typos happen too).

Fix 1: Match the Key ID on screen to the right key

The recovery screen shows a Recovery key ID for the volume it’s asking about.

1. Note the Key ID on the recovery screen — the first 8 characters are enough to identify it.
2. Go to https://aka.ms/myrecoverykey on another device and sign in with your Microsoft account.
3. In the list, find the entry whose Key ID starts with those same 8 characters. The 48-digit key under that entry is the correct one.
4. Enter that key. If you have several devices or keys listed, also confirm the device name matches the locked PC.

For a work or school device, check https://aka.ms/aadrecoverykey (or ask IT) and match the Key ID the same way.

Fix 2: List the IDs from a known-good Windows session

If you can still boot the PC (for example the prompt is for a second/data drive), confirm the active key and its ID directly. Open Command Prompt or PowerShell as administrator and run:

manage-bde -protectors -get C:

Replace C: with the locked drive’s letter. Find the Numerical Password protector: its ID must match the recovery screen’s Key ID, and the 48-digit value below it is the key to enter. If the IDs don’t match, you’re looking at the wrong drive or device.

Fix 3: Rule out a typo or the wrong account

1. Re-enter carefully. The key is 48 digits in eight groups of six. There are no letters — if you “see” a letter you’re misreading a digit.
2. Try a different Microsoft account. If the PC was set up by a family member or reseller, the matching key may be in their account, not yours.
3. Old printout vs current key. If the key was rotated since you printed it, the printout’s ID won’t match. Trust the key whose ID matches the screen, from your account.

FAQ

I have three keys in my account — which is right? The one whose Key ID matches the recovery screen. The other keys belong to other drives or devices and will be rejected here.

Why does my device show several recovery keys at all? Each time BitLocker is re-enabled or its key is rotated, a new recovery password (with a new ID) is created. Old ones can linger in your account but only the matching ID unlocks the current volume.

None of my keys match the ID on screen. Then the right key isn’t in this account. Check a work/school account or another personal account. Microsoft Support cannot retrieve or recreate a key, so if no matching key exists anywhere, the only path is resetting the PC, which erases your files.
