got a problem which i cant explain

usual, parked in garage, car stopped, locked.
as soon i enter house, the alarm starts blaring. i have to unlock the car from keyfob to stop the alarm and lock again.
random. i have been trying to analyze the problem over the last 2 months. i have done exactly the same every time, but random alarm blaring.

what do you all think ?

Mine is triggered by sound. Even when hosing it down with water. The water hitting it after a few minutes. Maybe a frequency (sound) is triggering it?

I had the same problem. Alarm module was replaced.
