Hi, my wife just bought a low mileage 2017 Punto Pop (from a dealer) to replace her 2008 Punto Grande (had since new). For the test drive, she was given the emergency key to use and the remote locking key was handed over after payment. Stopping for petrol on the way back (long journey) she discovered that the remote didn’t work. Using the key in the driver’s side door lock will lock and unlock the car. I’ve changed the battery in the fob but it still doesn’t work. Is it likely to need a new key fob or could there be another reason for the remote not working?
