What Causes Green Key Light Issues on Honda Civic?
There are many reasons why your Honda Civic’s green key light may be acting up. Such as:

2. Faulty Battery
Another common cause of a green key light issue is a faulty battery. If your Civic’s battery is not fully charged or defective in any way, it can lead to the green key light displaying on your dashboard as well as various other issues with your car.
3. Other Electrical Issues
In addition to a low fuel level and a faulty battery, there may be other electrical issues causing your Civic’s green key light to act up. These issues could include things like faulty wiring or a bad alternator, so it is important to have your car inspected by a professional if you are experiencing any issues with the green key light.
