1997 Acura RL factory Car alarm goes off for no reason

Hello, am really new here and searching everywhere for answers.I recently purchased a 1997 Acura RL with 136k mile on it. The facotry car alarm is going of for no reason. I disconnected the battery for 24 hours(neighbor recomended that) hoping that will fix it, problem is back and severe. Alarm goes off for minutes and minutes, (takes 5 or 10 seconds short breaks) and repeats again. My neighbours are pissed off at me because they cant sleep at night so do I. Alarm goes off at hot, cold and normal temps. Only TEMPORARY solution I found was by taking out FUSE for the horn which stops honking, but lights still flash. And this morning I couldnt start the car because lights were flashing up all night.I also replaced the remote battery, no luck:( if any of you guys can help me out or point me to the right direction, I would be thankful to you rest of my life and I will also make the donation, PLEASE HELP:( Thank you so much for your help in advance.
