I can't get my recovery key after laptop repair

Hello,

Recovery key ID is the ID for the recovery key, not the actualy recovery key itself. It should be a 48-digit number only key.

I wish I could share good news, but the truth is no one can get you the bitlocker key, including Microsoft staff/support.

Is this where you looked? https://account.microsoft.com/devices/recoverykey

Any chance your laptop was purchased used, or already set up for you? Or was it gifted? Or have you set it up with a different account at first? The key is stored with the very Microsoft account used to set up the computer for the first time, even if you had got rid of that account and set it up with a different account. So, if your computer was set up by anyone at the store you bought it from, it would be that person's account.

If you set it up with school or work account, it is worth checking here as well https://aka.ms/aadrecoverykey sign in with your work/school email credential in that case.

I assume you don't remember opting out of not saving it in Microsoft account, and saving it to a local file instead? That's another possibility.

If you can't find it at all, there's really no way to crack it. Bitlocker means business. If it can be cracked, then it means the encryption is not working. Your only option is to do a clean install of Windows. In that case, you do lose your files. I am very sorry. I hate to share this kind of information, but I rather give you the correct info.
