Default Need help with operation of duplicate key...

Bought a an Audi key fob from ebay and had it cut. I programmed the key throught VAG and it works, but the key would not sart the car (sometimes it starts but the keys light and hazard would flash and then the engine would turn off)
Any idea of what I need to do.

Any inputs will be greatly appreciated

you need to take the all your keys to an audi dealer and have your keys programmed to the immobilizer system. only dealers can do this....and you have to take ALL your keys with you, not just the one that isnt working. if you dont take all of them any keys not programmed will stop working with your car
