i think i had the same sigma alarm on my old 306, had so meny problems with it, randomly cut out all power so couldnt even put the hazards on! locked me in the car and just went off at random times, in the end i just asked a local car electrics place 2 remove the whole alarm, never had another problem with the sandard alarm, hope you got your one sorted mate
