I'm the original owner of a 2005 Mustang GT with active anti-theft on it and the car has over 91,000 miles. The horn chirps when I lock the doors with the key fob, but when the windows are down, you can reach inside and nothing happens. I never really thought anything of it except I have found out that it should be going off and it is not!
Anyone have any ideas on what might be wrong before I take it into the dealer? I tried deactivating / reactivating the alarm per the instructions in the owner's manual but that is not even working. You're supposed to start with the key in position 1, turn the key to position 3, hit the unlock button on the fob 3 times, turn the key back to position 1, hit the unlock button on the fob 3 times, turn the key back to position 3, then hit the unlock button 1 time and it should chirp - but it is not chirping at all!
Are you sure you have the intrusion sensors on yours? Should be two small 1/2 inch speaker looking things in the box where the lights are by the mirror. One points at the driver the other at the passenger.

Well I guess I will be taking it in to the dealer to check it out (and spend a minimum of $50-$60 for them to just look at it). Nothing I've tried has worked. I can stick my entire upper part of my body through the window, reach over to the center console, and nothing goes off. Also while testing the alarm, I tried opening the trunk and then hit the lock button to arm the car and it did not chirp twice like it is supposed to when something is not closed. That feature worked with the driver's door being open but not the trunk.
I had to have the engine bay repainted last October because of the bad brake reservoir that leaked and had to be replaced under warranty. Any chance that something in the engine bay could have become unplugged? Is there any part of the alarm system up in there?
You never did stated if you had the small holes at the top, by the interior lights. This alone will let you know if your car has it. before you spend money.
Stock for now. Two GT take off muffler, connected to a GT H-pipe.Upgrade instrument cluster. Shorty antenna. GT rear bumper. GT side skirts. GT front and rear sway bars. So many GT parts, and still a V6 engine. Damn. 18 inch Deep Dish Black rims, with polish lip. 255 front, 275 rear, soon changed to 285.
Well I don't know what to think. When I got home last night I checked out the active anti-theft system on the car.
I tested the activate / deactivate feature and if I turn the key to position #3 and then use the door lock / unnlock feature on the door and not on the key fob, that feature works.
I checked and I do have the interior eyes on each side of the map lights.
I also armed the car while sitting inside, waited for at least 30 seconds without moving then waived my arms around. The alarm only went off if I waived my arm / hand a few inches directly from the eye on the interior sensor.
My guess is that the sensitivity is set too low to detect the motion inside the car. Any ideas on how to correct this?
I would think that the active anti-theft that you pay extra for would be more sensitive on the motion sensors than the passive anti-theft. I just looked at Ford's Mustang Service Manual and it doesn't mention anything about intrusion or motion sensing in the section concerning the passive anti-theft system. According to the online manual, the Passive Anti-Theft System is controlled by a computer module in the car, is not controlled by the user and basically will the car will start only if certain conditions are met according to the computer module.
Personally, I've been disappointed with my Active Anti-Theft. What good does it do to have the system if all the system does when it goes off is to blink its lights and sound its horn? If you are inside and it goes off you may not realize the alarm is going off. And the alarm only sounds for a while - it does not keep going off (I guess the battery would eventually drain down if the alarm kept sounding continuously).
also, the motion sensors will only work if the system is armed with the keyless entry remote. if you arm the factory alarm by locking the door with the drivers door open, then close it, it arms everything except the motion sensors.
look under the hood and there should be a hood pin on the passengers side. thats also part of the alarm system.
I set the alarm after all doors, etc. are closed so the interior motion sensor should work. If I have a window down but the door shut and set the alarm, it should go off if someone reaches inside the car. Problem is the alarm does not go off until you wave your arms in the air directly in front of the sensor - within a few inches of them. Shouldn't it go off sooner and be more sensitive? Other owners I know have their alarms go off as soon as you reach inside just a little bit. Is there something I need to do to get the alarm to be more sensitive?
