There's a chance an ECU or two are fried. When I shorted-out lock wire on my '01 IS during the first attempt of the alarm install w/o diagrams, it literally melted the pin off the MPX module. Soldered a wire on top of it and called it a day.
You may want to check digital communication between ECUs. They go to +12V when at rest, if no communication has been sent for a period of time.
As Jason had said, the car will crank just fine w/ immobilizer engaged.
