Car alarm randomly going off

Hey guys and gals,

I have an issue, and I don't know if it's kids, animals, or the car itself. Last night it happened at 3am, tonight I'm sitting on the couch at 12.30am and it just went off again....

I don't see anyone out there around the car, not sure I saw anything last night either. Is there a cause for this? I just replaced my 12v battery in March, have a dead FOB smart key in a fire box (it's up on top of everything in the box). My current key was lying flat on the bench, nothing on top of it.

I'm getting aggravated. I don't want to tick my neighbors off, and I'm starting to think it's the local kids, but I want to know if anyone else has gone through this.

This is the dealer installed alarm (useless, yet very annoying at this point). I had it installed when I bought the car and it has paid me back on insurance already.

TIA, Amy

 

So it feels like its been a while, and after reading through here again I'm having the SAME problem, roughly a year later.


Quick Check of the charge on the battery indicates no issues, so I decided to pull the glass break sensor and see if it solves anything. Now, I've had this glass break sensor installed TWICE because the first time the tape they used quit and the damn thing wound up falling off. When it fell it looked like a foam covered mic... today when disconnected it There was NO FOAM COVER on the mic. I'm wondering if that makes any difference in how the mic perceives/picks up sound.

The quirky thing about the car alarm going off is it happens randomly the first time, and then within 7 hours, it goes off again- either right at the 6 hour mark or at the 7 hour mark. It doesn't matter if its parked in the garage or the driveway, and I haven't moved. We've added one more vehicle to the family since then, and I don't think thats an issue.
