Windows 10: Lost BitLocker key

I have an external hard drive that is BitLocker protected with my and scrapped model of my office laptop, my system admin tells me that the recovery key is not saved on my account. How can I unlock the hard drive and retrieve data?

Lost bitlocker recovery key

I have lost my bitlocker recovery key and tried following the recovery steps. I have also searched and tried following the command prompts suggested but none have worked.

 

Recorded BitLocker Key / Swapped Drive / Permanently lost BitLocker Key?

The gist: Lenovo support recommended a drive swap (from corporate computer with broken screen to temporary one). Initially, the BitLocker key worked and now it fails. IT told me it cannot be salvaged.

Computers: Corporate Windows Lenovo ThinkPad P15 Gen2's and we use "Intune."

Steps:

1. I'm instructed by IT & Lenovo to send my computer in for repairs seemingly unrelated to the hard drive (monitor completely black with power on). Lenovo warns "ANY" repair can destroy all data and recommends a drive swap. Confirm with 3 Lenovo representatives this is okay for relative novice.
   
2. Record BitLocker key and perform the swap.
   
3. Restart temp computer, input key on blue screen and everything's good but Microsoft Teams.
   
4. Repeat step 3.
   
5. Restart temp computer, input key on blue screen and Teams works.
   
6. Restart temp computer and BitLocker no longer accepts the key.
   
7. Lenovo sends back fixed computer. Install original SSD. Screen is fixed, but BitLocker no longer accepts the key.
   
8. My Account shows two devices -- with the same name -- associated to me. The "Inactive" one has my recorded key. The "Active" one says, "No BitLocker recovery key found for this device."
   
9. IT says BitLocker keys should rotate when doing what I did. Initially, they failed to rotate -- the reason why steps 3 - 5 "worked." Then, the rotation happened -- step 6 -- but the new BitLocker key wasn't saved anywhere. I am currently assuming they would have checked something like the Azure Active Directory.
   
10. Part of me doesn't believe the BitLocker key couldn't have been saved anywhere. I know what I did isn't typical for an employee, but still there have to be a lot of drive swaps in the world -- saving BitLocker keys can't be this fragile.
    

I know this is long and appreciate any assistance. Have a good year in any event.

Sincerely,

Tim
