I know that you can disable the horn both for remote starting and locking with the remote because my Jeep doesn't do either of those things.
To disable the horn when locking the doors, I might have gone with this suggestion - https://www.wranglerforum.com/threads/turn-off-horn-when-locking-jeep.1234225/ - but I'm not at all sure about it. Some sites say that will also disable the horn when using the remote start. Don't know for sure, and since mine doesn't honk in either scenario I'm not likely to experiment!
Google search is your friend!
(Edit: I didn't realize that people had already posted the solution a few hours ago. I thought I was at the end of the thread, but it was just the end of that page!)
