Hello AyazB,
thank you for posting on the Microsoft Community Forums.
If you have previously saved your BitLocker recovery key elsewhere (e.g., printed it out, saved it on a USB drive, or stored it in another location), try to locate it. For the details, you can see Find your BitLocker recovery key - Microsoft Support.
**mportant:**Microsoft Support is unable to provide, or recreate, a lost BitLocker recovery key.
Kind regards,
Lei
