I got a puma yesterday,few little probs but nothing too bad. The thing is the remote on the key doesn't work. This wasn't a problem as i just used the key to open the doors manually,then one of my friends said the batteries were probably flat so he took the key apart to look at it. The batteries were ok but the key still wasn't working. He tested the cicuit board with his meter and said that it needed a new diode or something which he then snapped off with a pair of pliers :x . now when i unlock the car the alarm goes off so i have had to remove the fuse :-( . Any advise please?
