I was under the impression that if you were to use an ignition key that had the wrong chip, or no chip, the immobilizer circuit disabled the ignition, and it was necessary to input a code through the radio to re-enable it. I guess I assumed this because I couldn't recall ever reading how the system was initially programmed to recognize the right chip, of how the ignition was re-enabled. If it's as simple as using the right chip, I'm surprised that more Honda's aren't stolen.
I'm glad to learn that I was mistaken. Thank you.
