Hi, thanks for the reply. I understood that the fuse wasa out becuase the central locking didn't work, was just happy to continue locing and unlocking manually until such a time that I had the time and resources to investigate properly.
In answer to your questions - no....the fob will not unlock or lock the doors at all, no response. And yes, it is the round key fob.
Very frustrating...mechanical problems I can deal with quite happily...electrical problems are witchcraft.
