Q: 200-dodge Durango car alarm won't shut off

Usually when the alarm fails to go off you can pop the hood and disconnect the negative battery cable. By doing this you should be able to stop the alarm from going off. I would recommend leaving the battery unplugged for about 10-15 minutes just to give all the computers in your vehicle a chance to reset. If the alarm still goes off when the battery is plugged back in, you can try to press the unlock button on your key fob to disable the alarm system. If the key fob does not work, you can also stick your key in the door and turn it to the unlock position to disable the alarm. Another possible way is to find out which fuse controls the alarm system and remove it to disable the alarm. If none of these options work for you, I would the recommend having your electrical system inspected by a qualified technician, such as one from YourMechanic, to determine the exact cause of the security issue you are having.
