As mentioned earlier, if the locks are not working in addition to the alarm condition the obvious place to start is the body control module in the trunk area. Now that you know this forum exists it should be the first place you go when you encounter a problem. Dealers and mechanics often don’t know and understand the Crossfire well and taking it there will soon cost you more than the vehicle is worth. There is also hey Crossfire tech parts and rescue Facebook group that is helpful for asking questions and getting quick answers from experienced Crossfire owners. This forum is valuable because you can search and often find the exact problem you are experiencing a long with a detailed solution before asking a question that has already been asked A dozen times over or getting bad/conflicting answers.
