Hello Crazysioned4,
Thank you for posting. We know how important it is to be able to access your Mac! As we understand it, you're seeing a firmware password prompt, and you've been unable to locate the password, correct?
It sounds like you might've already reviewed this resource: Set a firmware password on your Mac. You mentioned that you don't have an Apple Store nearby. Have you double-checked to see if there might be an Apple Authorized Service Provider that's closer? Apple - Find Locations. The text below provides further detail on what you would need in this circumstance:
If you can't remember your firmware password, schedule an in-person service appointment with an Apple Store or Apple Authorized Service Provider. Bring your Mac to the appointment, and bring your original receipt or invoice as proof of purchase."
We hope this is helpful. Kindest regards.
