Any help please, I’ve got a problem with my SIGMA M30 alarm on my W-reg Subaru Impreza. The fob won’t open/close the doors or won’t deactivate the alarm, so I can’t start the car. I don’t know the pin code to disarm manually. I had an alarm guy to have look at it, now the alarm stopped, it won’t work at all and the red light on the dash won’t flash. But I checked the pin pad, still works. There is a large antenna transmitter about 100 meters away from my house (could that interfere with the waves and prevent fob functioning properly?). Any help is really appreciated.
