Some of the neighbors garage doors have been opening on their own at random times. They have tried changing their codes in case someone has a door opener that is triggering their door to open but it has not helped. The houses are spread out down the street that this is happening to so they not all next door to each other. Just now we were sitting in our kitchen and our garage door opened on its own. Some think it might be someone's cell phone. Does anyone have a solution to this? We hate to have to lock our garage door on the wall key pad in the garage every time we go away because then we can't open it with the remote when we come home.
