2001 Honda Civic Q&A
2001 Honda Civic Question: what does green key indicator light on dash mean?
This is the anti-theft warning system icon. - patrick mannion
The green key icon is for the immobilizer system on your vehicle. Your ignition key has a chip in it and the computer won't allow the engine to start if it doesn't recognize the chip in the key. When that happens, or if there is a malfunction in the system the key indicator light will flash consistently. - rdude135
Its the chip in your key saying it doesnt match with the computer in the car. The manual says the car shouldnt crank when its flashing, but mine does. I can't fugure out how to turn it off though?? - karilynrene
