Although this isn’t as big of an issue as say in the 1990s when car alarms were still a new novelty with a few kinks in the design, there are a few common culprits behind this. One issue could be a faulty key fob that is malfunctioning and sending the activate alarm signal to your car’s alarm even when you aren’t pressing the alarm button. If you suspect this is an issue, consider changing the battery on your key fob. But a dying car battery can also be the cause of this annoyance. The easiest way to remedy this is to switch out to a new battery or find a good Samaritan with jumper cables to help give you a boost.
