You should be able to recover it out of your one drive.

However, since you said someone else set it up the key might be it their one drive. So, you would need to find them to unlock it. See article below on BitLocker recovery keys.

Decrypting the drive without thew key is unlikely, so I do hope you can find out who did this or where the key was stored.
