Over this weekend, both Friday and Saturday night, at some point between 12:00 and 2:00 (don't remember exactly when), me and my friends heard a car alarm going off at my apartment complex. After 3 or 4 minutes, it stopped going off, and we didn't think anything of it. Well, a car alarm just went off again (15 minutes ago). Me and my friends went to see what car it was, and it was mine. So I turn off the alarm, unlock the car (the theft light was on, if that means anything), put the key in, turn it on, turn it back off (theft light goes off), close the door, lock the doors, and head back to my apartment. We won't 20 steps away from the car and the alarm started going off again. So I turned it off again, but this time, I just went ahead and unhooked the battery cable (I didn't want to disturb the neighbors anymore than I already have). And here I am. I have no idea on why it has done this. I am currently assuming that it was my car alarm going off on Friday and Saturday night. I find it strange that it has just started doing this, and that it has always happened late at night like this. But at the same time, it didn't go off last night? Anyone have any ideas? Cold weather have something to do with it maybe? Btw, it doesn't have an aftermarket security system or anything. Just the stock Ford whatever-it's-called.
