Key not communicating with ODIS or VCDS - 2011 Audi A4 2.0L

[bobbyhtike]

If its the correct key for the vehicle by part number then yes if it was unlocked correctly. Having said that the pcb does not have a part number on it only the remote case does. But I will assume you purchased the keys with cheap china plastic housing that does not have a part number on it therefore it will be almost impossible to determine if they are correct or not. You can try but I have my doubts.

Gotcha, so to be clear I need a key from another 2011 A4 with same key start style? Basically easiest way is to go through dealership? Can I still reunlock/readapt my current keys with the proper procedure so that they can be used with ODIS? Or just need to get another correct key? I have attached pictures of the key housings for reference below.
