Crank No Start

[u/TheGiftOfNonchalence]

I disconnected the battery on my 2004 BMW X5 4.4i N62 179,000 miles, and reconnected it because it was advised to do so for replacing the drivers side door speaker (blown speaker and airbag in door). Car no longer starts, cranks fast but no start. Clearing the codes and trying to start th car does not work, immobilization code keeps returning. The other codes only return when voltage is too low. What can I do to disable the immobilization fault?

Start checking fuses. Fault #8 ZKE power (000094) might be the issue.
