Gents,since yesterday it would seem I can sometimes unlike the car with the electronic dongle but when I insert the key in the ignition it makes a click and all power goes off.It sometimes comes back if I wait,I have tried the battery switch in the boot but nil help.Manual lockin/unlocking ok but obviously no power/no ignition etc.Any ideas or help gratefully appreciated.Car stuck in car park at the moment.Brgds
