Wat does it mean when the green light with a key flashing on my dash in a 02 eclipse

Car shape with key symbol inside it. It is part of the anti-theft/immobilizer system that all eclipse have. For car's with alarm, it serves as an indicator that the car alarm has been armed. If it blinks, it usually mean that there is a problem with the key.

Yes that would likely do it with the aftermarket key.use original key.that will help.

this will help thanks

Generally speaking, you have a chip in the key that is read by the security system. If the system does not "see" the right chip, the system locks out the ignition and fuel systems.
The new key probably does not have a chip or the wrong chip.

Is it a strong crank? If it is a weak crank it could be your battery doesn't have enough juice. If not that it could also be starter. If neither of those check spark, fuel and pressure in that order from easiest to biggest Pain in the neck.

try activating and deactivatin your alarm you can do this with the key pad or the key turn it twice to the lock position than turn it twice to the unlock position this will unlock both doors, needless to say if you are getting a little green light on your dash with a key in it it is the imbobilizer device when it is in imobilizer status it will not let the fuel injectors prime up

Remove the bulb from the socket in the dash board.

The green key light on the dash is your immobilizer system. If it flashes at you while you are cranking (no start). This means the key that you are using is not programmed to the immobi control unit. Try using another key. if all other keys are lost you'll have to get it down to you local honda dealer. it takes a special honda scan tool to program these keys to the control unit. If you don't want to spend money on a tow truck, ask you dealer about the Brake Code. This is a code specific to each vehicle. If your keys are lost/stolen you can input this Brake Code into the control unit by using your e-brake (special procedure). this will give you 10 free starts to get it to your dealer. (limp-in mode).
-hope this helps

that means it needs service. also probly means that something is either loose or broken wise. you were probobly receiving a service engine soon signal when you put the keys in the ignition and turn it one slot to where the car is running on battery so the radio should work. and thats where the idicators would of been going on. and you probobly didnt notice those

The green light on the dash flashes when the lights are off or if you have just the day time running lights on. If your lights are on the light should go out. or if a head lamp is out it may stay on
