My grandmas car got broken into. Her car is parked like 6 feet away from her bedroom so if an alarm went off she would hear it. But the alarm didn‘t go off. I don‘t understand how it wouldn‘t go off. The only thing I can think of is that since you can wirelessly turn off a car alarm then there‘s some way to get onto the frequency that that alarm runs on and then just turned it off.
Most car alarms are triggered by pressure movements inside a car or other vibrations. Basically if anything significant transfers weight inside of the car, the alarm will go off.
