Has anyone had problems with central locking i.e. unable to lock/unlock if more than one metre away from the car. My local dealer fitted a new circuit board which increased the distance in which the key operated but since then the passenger window failed to operate. The dealer then suggested that the wiring loom was faulty, having replaced that ,the window still does not work, they are now going to fit another circuit board but they say it may reduce the operating distance of the key back to its original state.They wondered if the distance problem was due to the car being an import as the 172 they had in stock had no problems with locking.
