The dash is showing the flashing green key.
I've tried both keys/fobs.
The engine just cranks.
I removed and reinstalled the battery (thinking maybe Microsoft tactics might work).

I'm assuming there's an issue with the key immobilizer receiver/sensor in the ignition?

Does anyone have experience with this failure? I've read that it's a "dealer fix"... but does that mean dealer or just not DIY? Can a good Honda/Acura shop handle this? Or, is there some magical, proprietary Acura-only tool only the dealerships have?

Thanks!
