Question about 2004 Honda Odyssey
That green key is the immobilizer system indicator. It comes on for a few seconds when you turn the key to ON. It will then go off if you have inserted a properly coded key. If the key isn't coded properly, the green key indicator will flash and the engine won't start. The indicator also blinks several times when you turn the key from ON to Acc or Lock. This is normal. (From owner's manual under "Indicator Lights")
