key remote problem

[75er]

Hi, I've just bought my first 75 a CDTi tourer and I'm delighted with it. Please to join such a helpful forum as well. One immediate problem I have is that my remote keys don't work. The lights on both keys operate when the buttons are pressed, so I guess the key batteries are okay but they don't remotely operate the doors. I've looked on the forums but can't see any advice directly dealing with this, although apologises if advice on this has been posted up before and I can't see it. I guess I'm looking at a garage reprogramming job am I? Do many places still undertake this work?

Thanks.
