A green key shaped light is flashing on the dashboard. What does it mean?

In general, 'green' means nothing to worry about. Are you sure it is not one of these symbols pictured here? http://www.begoodtoyourvw.com/service/dashboard-indicator-lights/

Hello and welcome to Fixya!
As a first course of action, I strongly suggest that you remove the positive batter connector and let it sit for atleast 5mins. before reconnecting it. This will reset the system and can get your vehicle back to it's normal operation.

Please do keep me posted on the progress. I'll be glad to help you out. Hope this helps and thank you for using Fixya! Have a good one!

"Security" or Key-shaped light flashes on the dashboard ? Your car might be equipped with an immobilizer. (you can find more information about the immobilizer in your owner's manual). The immobilizer allows the engine to run only if the correct key is used. If your car has an immobilizer, you probably see a "Security" or Key-shaped light coming on on the dashboard every time you turn the ignition ON. If this light is flashing when you turn the ignition ON, it could mean that there is some problem with an immobilizer or the system does not recognize the key. If the immobilizer doesn't recognize the key, the engine wold not start at all, or would start and then die in few seconds.
You can try a spare key, if it won't work, your dealer is the place to call. Sometimes, the key is just need to be reprogrammed.

dont forget to take your key with you.

the red light is telling potential thieves that the car is immobilsed(dead) without the right key.....

its th factory instaalled security system activating.

it means you have a rear tail or brake light out.
