The alarm unfortunatly is only as good as the installer and the job done installing it. Last week I was walking my dog and walked up on two ladies standing on the side fo the road with an excursion parked in the middle of it. I could see them from some distance and as I got 100 ft the alarm went off and I noticed teh one lady motioning that the alarm would not shut off. As I walked up and asked them about it she explained that it had been acting up over the last few days and this time went off while it was driving and shut it down. They were happy when I told them I had installed security for over 10 yrs and could probably help. The alarm would not reconize the disarm funtions but would still report that the alarm had been set off. I told her I could possibly disconnect it if she liked and she said to have at it. I was amazed that I opened the door and the alarm beeped but did not go into full alert. When I peaked my head under the dash(which was not hard in a lifted explorer) the alarm and all of its wires were exposed just above the dead pedal. Took 2 secs to disconnec the hrns and and completely disarm the 2 way pager alarm, she was happy and sad at the same time.

If they were lookin under the front they could have been looking to see fi your alarm siren was exposed where they can cut the wire. I would peek under the hood and make sure it is not exposed, but if you want be to give it a good once over I would be happy to help protect another stang......
