The battery went flat on my mondeo key fob, using the key allows me to do everything including set the alarm. Anyway told the garage at service time, he said take it to the main dealer, did that , they said take it to halfords, they said ring ford, rang ford, ford say takeit to main dealer did that , they said take it to halfords. Anyone remember the flanders & swann song "the gas man cometh" I only wanted a new battery!!
