Does it require two presses on the remote locking keyfob and the subsequent "'beep" of the horn to actvate it? Or is it activated with just one press of the lock button on the remote? I thought I read somewhere it took two. In my house my wife sometimes forgets to lock the cars at all, I know it will be HELL to try and get her to press the remote twice,
tell me it's not true....and ONE time will do....

Hi CDMILAN. :wavey: Rest easy, one press will do! :lmao: According to my MKZ Owners Manual, the alarm system is activated in any of several ways (I'm sure if you check your manual, you will find the same information):
1 - Pressing the lock button on the remote once. The lights will flash.
2 - Pressing the power door lock button on the driver or passenger door, with the door open, and then closing the door.
3 - Pressing the lock button on the remote twice. This will do a system check. If all the doors, the hood and trunk are closed, the horn will beep once, and the lights will flash. If any are not closed, the horn will beep twice, warning you that something is not properly closed.
4 - If you have the "Keyless Entry" keypad on the drivers door: Pressing the 7*8 and 9*0 buttons at the same time. The doors will lock, and the lights will flash.
I would think the system would be the same on the MKZ, Fusion and Milan, with the only variable being whether you have the "Keyless Entry" keypad.
To "swooshUSN": :wavey: As far as reaching in and popping the hood or opening the door with the inside handle: Yes, if the doors are locked properly, the alarm system is armed. If you reach in through an open window and pop the hood, trunk, or open a door with the inside handles, the alarm will go off. You need to disarm the system first, either by using the remote to unlock the doors, or the key in the door lock. It had nothing to do with accidentally hitting the "Panic Button".
The "Panic Button" just sounds the alarm horn (or stops it), and does not turn the actual "Perimeter Alarm System" on or off.
Again, this information is all in your "Owners Manual". For the MKZ, it is on pages 97-99. Not sure if it is the same pages for the Fusion and Milan, just check the Table of Contents for the "Perimeter alarm system".
Good luck. :cheers:
PS - I know this thread was a little old (and that it looks as though CDMILAN is no longer around), but figured I would add the info from the "Owners Manual". It could be helpful to others.
