Hi, I've just bought a Fiat Brava SX 80 1.2 16v Y reg, and because of the hopeless car dealer who didnt know himself (god knows how he's selling cars!!:bang: ) On my key fob, I got a round fob attached, could anybody possible tell me what this is for?? I've put brand new batteries in it and it still doesnt do anyting. I thought it maybe for central locking and possible for my alarm whether its activated or not, just got a red light flashing constantly in my car!! Would appreciate any sensible comments.
