Why would the Alarm randomly go off when parked?

What is your question?

For quite some time now my alarm will go off for no reason. It doesn't happen often. Maybe once or twice a week regardless of how often it's been driven or how long it's been parked.

What makes this problem better or worse?

It’s random

How long has your 2008 Kia Sedona had this problem?
