Alarm oddity

Hey everyone!
So, for the past few nights, my truck has been doing like 6 rapid honks in the middle of the night and then stopping. Any ideas what could be causing this? Any help is much appreciated

 

Some punk testing your alarm. When you get tired of hearing it and decide there's something wrong with your alarm and leave it off, then they'll smash the window and steal your stuff. Or it's the repo man.

 

Believe it or not, this same thing happened to me last winter when the temperature started dropping. It ended up being a bent check arm in my door had bent the window track and as it would get cold, it would cause the metal track to pop loudly, which would cause a vibration in the door, and set my alarm off-probably from the shock sensor. Changed parts, no more issues
Also to note, I read that a weak battery can cause this in cold weather. Hope this helps!

 

aftermarket or factory?

 

Sounds like a warning violation for the shock sensor. Could be a cat jumping on your truck too
