E36 Stuck in Alarm/Immobiliser Mode

[3seriesman]

Hi All, wondering if I could please get some advice. In recent days my hazards and headlights have just started to flash all of a sudden. Now it just flashes, car cranks but does not start. Central locking and electric windows do not work either. Battery is in good condition. Please assist. Thank you

What year model E36 is this?

1993 - 325i automatic

Potentially one of the door switches or bonnet or boot switch that's the issue
