Is there any way to turn off the horn when I unlock my car with the remote. It beeps wether I unlock it or lock it. I bought it used and it had no books with it, those are coming.

 

I have a 2010 and the horn does not beep when I unlock it, only beeps when I lock it when I hit the remote twice. If it is still under warranty take it in to the dealer...

 

There are provisions to turn these types of features On and Off through the driver's information center on your dash board.

The owner's manual "books" you will be receiving will tell you how to navigate the information center.
