Denali- How to stop beeping horn when unlocking with key??

[hmhs]

I have a 2010 Yukon Denali & I was wondering if anyone knew how to stop the horn from beeping whenever I open the door with a key (instead of the remote- this does not happen if I use the remote unlock). This has become very annoying for my husband particularly because he does not keep a remote for my car on his own key chain.

Any advice would be much appreciated!
Thanks!!

Did you check the owners manual?

Try walking thru the setup items on the buttons to the right of the instrument cluster.
