New here - Question about alarm system
 

[&:]I've got a 2005 Sebring convertible with the factory alarm. Recently, in the a.m. when I hit the unlock button, the horn starts honking, lights flash, etc. It's a long horn sound, not the normal honk-honk-honk. Even when I get in and turn the car on, it will continue honking, then stop eventually, maybe 30 seconds???? The other day, I got three houses down and it started the long blaring again, finally stopped after a few. Yesterday, after it stopped, i drove about a mile and it started honking again, then stopped. Any help? Thanks.
