Hi, I have owned my 2012 C3 for nearly two years. It has just developed a fault whereby every time I close the driver door, the central locking immediately locks the car up. This is regardless of whether I am just getting in, or completing a journey. Yesterday, it locked when I got out of the car, having left the keys in the ignition. I had no choice but to call the AA who managed to break in. It would have been a much bigger problem if my baby son was in the back of the car. Obviously I am being much more careful now. Any ideas what the problem might be and whether it will be expensive to fix? The fault seems to have started shortly after getting the car washed. Could this be a factor. If something has got wet, is it likely to resolve itself. Thanks
