The Alarm System seems to go off after the car is parked on it's own, I had a mechanic check it and he discovered a second alarm system which he removed, This problem occurred again the next day and I returned to my mechanic and had him disconnect the horn as it was bothering my neighbors. I do not use the remote to lock and unlock the car anymore and the problem seems to be fixed, but I have left the horn fuse out just for sake.
