Hello!! I had a problem with my cars central locking too. When it was at Pandit Auto, Pune, for scheduled servicing, somehow, water entered the fuse box area of the car and shorted out the central locking. I found out about this after I took the car back from Pandit while I was parking the car. The thing was that the car would not lock at all, manually either. After consulting a Autocop guy, I was told that Fiat and Ford have different type of locks and actuators which cause this, if the lock or actuator gets corrupt then both will stop working. I think that the design sucks, at least in India. I had to wait for 4 weeks for the new set to come to Pandit Auto. My advise is, ask your dealer to change them at once it they are under warranty.
