it's in the shop already, so the mechanic should deal with this.

by the way, the immobilizer will let you start the car, but it will kill it as soon as it starts if there's a mismatch between the key and the stored value.

so if it's not cranking, it's not your immobilizer.

Immobilizer would not stop the car from turning over.

Rat or rodent ate a wire or shorted something? Pretty simple to check whether voltage is getting to starter or not and go from there. Do the headlights work with the new battery or is everything dead or does just the starter not work?
