How do I fix a horn honking problem caused by opening a drivers door. on 1992 Mitsubishi Diamante

when I opened the door on the drivers door the horn starts beeping on a regular basis like its an alarm system.Does thei car have an alarm system ? and if so how do I fix it or dis-able it. I got this car 2nd hand with no instructions period. If it is not an alarm what is it and how do I repair it. The horn only stops when the battery runs down or is unhooked.

i BOUGHT A USED 1998 MITSUBISHI DIAMANTE RECENTLY. ONE DAY THE HORN JUST STARTED GOING CRAZY IN A VERY CROWDED PUBLIC PLACE. AFTER TRYING EVERYTHING YOU DID........A YOUNG MAN CAME OVER ASKED FOR THE KEY AND HE PUT THE KEY INTO THE DOOR AND TURNED IT. GUESS WHAT? THE HORN STOPPED BEEPING........TRY THAT IS MIGHT WORK FOR YOU
