Why? I would not start messing with a factory ubit. It's highly recommended to leave it alone. I have 2 alarms on my car without any problems, the ford alarm can be integrated without any problems. Thos e factory alarms are a major part of your wiring system and can lead to a very big problem if you start changing them. And that leads me to ask why would you want to disconnect it in the first place? If it's acting up then look at the fuses and make sure they are all good and making good contact on the prongs. Make sure that all sensor contections are clean and plugged in completely making contact.

Hello. Alarms are a pain and can cause problems. The best thing to do is disconnect the fuse for the alarm in the fuse panel of the car, then the alarm will not work at all. Also becarefull that it does not cause problems to the car itself. Good Luck.

last ditch effort , disconnect the battery and wait 10 minutes and hope your system re sets itself , not knowing what make your car is , makes this hard to answer, or if it was a factory alarm or aftermarket ,,,, If its a factory alarm, you can do this Open the door with the key. (the alarm will sound but ignore that)
Close the doors, put the key in the ignition
Turn everything off that takes power when you got the ignition on.
Turn the key into first position (IIRC) the alarm will go off again, but still ignore that.
Then sit back and relax for exactly 15minutes, without touching anything nor opening any doors.
Then turn off the ignition.
That's it. Your alarm is now disabled.
Start the car and enjoy.

if it is aftermarket then all you have to do is disconnect the wire to the alarm that has power constantly going to it. if it is factory then you will need to make sure you tie the starter kill wire back into itself so you have a continuous circuit and not a broken one so that the car will still start. factory alarms are always a pain to locate where the starter kill wires are but usually the are near the steering column.

BEHIND THE DRIVERS KNEE PANEL IF IT IS FACTORY IT SHOULD BE JUST BEHIND THE DUCT WORK YOU CAN ALSO JUST UNPLUG THE PIGTAIL HARNESS IN BETWEEN THE IGN. SWITCH AND THE ALARM (PLEASE RATE THIS)

try removing the remote fob battery for 10 secs then replacing, i get this problem a lot if the fob battery is low.

get a gun & shoot it .they were a piece of **** when put in. or find someone to install a new alarm.

Why would you add another alarm?? I recommend you remove the aftermarket alarm, it is the cause of the issue, there is no fix, the factory alarm can't be disconnected, it is an intergal part of the starting system.
