Hello Lisa Boettcher,
thank you for posting on the Microsoft Community Forums.
To recover your BitLocker recovery key, please follow the steps in Find your BitLocker recovery key - Microsoft Support.
**Important:**Microsoft Support is unable to provide, or recreate, a lost BitLocker recovery key. If you can’t find the BitLocker recovery key and are unable to undo any changes that caused it to be needed, you’ll have to reset your device using one of the Windows recovery options.
Best regards,
Lei
