Car Alarms: alarm, alarmtek, horn blows

Question
my alarm continues to go off (lights flash,horn blows) after a couple hours of locking my doors. this happened after my car was hit with a basketball. what can i do to fix this?

Answer
I'd start with any door repairs necessary to put it back
the way it was. Next, OEM/FACTORY alarms depend on solid battery power.
Any spike, or drain, would set off that system.

So if you have not changed the battery recently, do that first.

Happy Easter.
