Ok, do the following -

Place key in the ignition and turn to on position, open and leave open the driver door. Disconnect the negative battery cable for 1 minute, then reconnect. Alarm should sound for 60 seconds and then stop. Cycle key off for 5 seconds and then crank engine. Alarm should be reset at that point and off.

I will opt out and see if another expert knows of another method

Hi I will try to help the situation but first do you know where the alarm siren is located or if the horn is blowing do you know where the horn assembly is located, usually under the hood or in the grill?

Customer: replied 4 months ago.
The alarm siren is located by the grill on the passenger side.
Expert:  Cardoctor71 replied 4 months ago.

Ok, temporarily cut one of the 2 wires going to it, until you can have the alarm system properly diagnosed and repaired, that way you don't have to listen to the ear piercing sound.

Expert:  Cardoctor71 replied 4 months ago.

Is the alarm aftermarket or factory?

Customer: replied 4 months ago.
The way that you didn't even try to suggest anything and immediately told me to cut wires to turn off the horn is completely unprofessional. I am fighting to have whatever money was charged to me to be refunded because of the fact that you are unprofessional. If this is the way that you handle all of the problems with which you "help" people, then you should consider just not answering any more questions.
