Hi - Apologies if this is obvious, but I cannot get the key fob on my 997 MY 2006 to operate correctly after not using the car for over a week. I beleive that there is a way in which one can re-sync the key with the car, but I cannot remember how to do this. I can still get in / out with the key and everything else works fine, just not the fob entry. Any ideas much appreciated.
