How do I stop My 2017 Trax Alarm from randomly going off?? The past few days my alarm has randomly been going off, at first I thought I bumped into the fab but it’s not that easy. I’ll be sitting in my house when the alarm will go off, and stay on until I unlock the car. It only happens when I lock the car. Does anyone know why this is happening or what I should look for in order to fix the problem? Any help would be awesome!
