And at flashbk2's suggestion, here are the steps for the horn chirp activation/deactivation:

"The horn chirp that signals that the doors have been locked can be turned on or off by using the following procedure:

1. Insert the key into the ignitioin switch and turn the switch to the ON position.
2. Press and hold the Unlock button on the transmitter for between four and ten seconds.
3. Continue to hold the Unnlock button and press the Lock button.
4. Release both buttons.

A chime will sound to signify that the process is complete"

I did notice that if I sit in my car after I take the key out of the ignition and it's running on the timer, a few seconds after I take the key out, I hear a little chime. I'm wondering if that perhaps is the chime that is turning off the horn chirp. Any thoughts?

If anyone else wants to give it a try and post their results, I'd be interested in seeing what happens!!!
