How do you shut of a malfunctioning car alarm without the fob that comes with a

new jeep? I have a '96 jeep grand cherokee ltd that came with a factory alarm. I bought this car one year ago, but didn't get a fob with the car, so i assumed it was either lost or broken. Several weeks ago, the alarm activated in the middle of the night, so i used my key to open the door and start the car , which took care of the problem,until last night. I was leaving my girlfriend's place to go home, and as i unlocked my door ,the alarm went off. This time, i couldn't turn the alarm off by starting the car. It would turn over and immediately shut down, allowing the horn to keep blowing. Naturally our local boys in blue responded as though the world's largest doughnut shop had just opened for business,with everything being free for anyone who could display the best gestapo technique. I was assured by the leader of the pack that jeep did not have an alarm as an option, even though i was showing him the owner's manual that came with the jeep. I opened the hood and one of these brave souls disarmed my system by removing the horn's fuse from within the little black box on the passenger side of the engine compartment. That stopped the noise, but the jeep cannot be started (apparently the alarm is still activated). If i disconnect the battery and then re-connect it will the computer reset itself and allow normal vehicle operation? I would like to have this question answered by either a chrysler technician or an alarm technician, not someone who is just guessing, like myself.
