Hi, everyone:

I have purchase an Audi 2009 A5 coupe days ago, every times after I insert the key it tells me ignition lock defective. Is there any solution for this right now? I do not have any OBD2 software, and I only have one key.

Also I can take my key fob out of my ignition after I start the car or during driving, is it normal?

I believe I have easy entry feature on my car, but it's not working though.

Is it something wrong with the key or ignition?

Many thanks.
