Re: anti theft shorted out.
Sounds like a faulty relay, so you can remove the relay that is clicking to start and see if that cures the fault, and if not replace it and try another one until you isolate the fault. You may want to check the door switches to see if one is stuck. Your ignition kill is obviously activating along with other switch/relay possibilities. Good luck, and please post back your results so we may move to other possibilities.

Your alarm should turn off with remote. If won't my wild guess is that somehow your alarm got short-circuited. Does your car start with alarm on but anti-theft turned off? If does, disconnect horns and take your car to alarm installer to get it checked.
First, Have your Battery tested. The Alarm systems in Ford made Products are very sensitive to Voltage. There are 3 systems in the car which interrupt power, the Alarm system (horn honking) and the Battery saver and finally the starter interlock system.
The Alarm system will do several things to disable the car from starting. It will reduce the voltage to the starter to prevent the engine from turning over. Some will even kill the ignition system so that if the starter is jumped, the car still won't start.
The Battery saver will disconnect any system to prevent discharge below a minimum threshold. Unfortunately, when the Alternator is working extra hard to charge a really bad battery: it will disconnect the charging circuit because it reads the Draw going to the Alternator to produce the power as a parasitic drain. Even at 70mph I have seen the charging disconnected and the vehicle coast to a stop when the electric runs out.
The last system worth mentioning is the Starter interlock. Under the dash and at the top of the Brake pedal lever is a switch. When you press the brake pedal, the switch allows the starter to crank provided the shifter is not in D or R. Drivers feet routinely hit this switch and either move it or break it. When it breaks it can short and drain the battery.
As you mentioned a Random problem, the Brake switch can shake to create a random problem if it is loose or broken. Your rear brake lights can be affected.
With the horn honking, at least part of your problem is the Alarm system. You can have a bad ignition switch too, which reads the keychip to disable the alarm. Your keychip may be bad and setting off the Alarm.
I had a new Lincoln myself which set off the Alarm randomly. I actually slept inside the car one night so I could turn off the alarm in the Apartment complex parking lot. Did'nt know if it would start again if the battery was disconnected and then reconnected. The Battery was shorted with less than 1000 miles on the car. It was a factory defective battery less than 3 months old.
But your car has many years and miles on it so it was worth mentioning the wear items. I hope my solution is helpful.
Might possibly be. Pontiacs were really tied into that anti theft security system. They were notorious for breaking. Here is a link to a site about these SECURITY systems. And possible DO IT YOURSELF solutions. http://vatspasslockpasskeysecurityhelp.yolasite.com/
