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.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.
