I have a 2006 Jeep Commander and I can't get the horn to stop sounding. About a week ago I lost my keys and realized they might be inside. I got into the vehicle by using a coat hanger to lift the lock. I then disconnected the battery while I looked for the keys so as to not disturb the neighbors. I found the key but now it won't disable the horn. Even when I put the keys in the ignition and turn on the car. The remote unlocks the car but won't turn off the alarm and the car starts. Please advise.
