Surely the frequency will always be the same but the actual codes transmitted will be different. You will need to 'pair' the keys together but I don't know whether you can use the newer model key or not with your A3.

There are plenty of details online on how to reprogramme the key to work on your car. I have had to do this myself and it works fine.

I believe there are two ways to reprogramme, one that has to be done by Audi and one that you can do yourself.
