Taking my 2010 Challenger out of winter storage and replaced the battery. As soon as I hook it up the horn goes off and will not shut off. I can start the car, but the horn keeps going. Does not matter which battery terminal I hook up first. Any ideas? Driving me deaf! Thanks in advance.

I will ask the obvious question....Did you use key fob to try and disarm the alarm?

I tried it and it set off the alarm too which caused more beeping.
