Alarm going off
P.S. It did this around when I first bought the car, but then i disconnected the battery for a couple of days and didn't have the problem till now. And I don't really remember the weather when it happened before.
Usually moisture builds in it and causes it to misbehave.
You can open it and let it sit to dry and put it back in the car after a day or so.
You can also just unplug it for good like most of us have, unplugging it doesn't turn off your alarm completely.
