We just purchased a 2010 V6 Automatic, The horn chirps once when you lock the car from the remote & twice when u unlock. I thought you had to press the lock button twice before the audible chirp happened, but not the case here. Also after turning off the ignition and opening the door the horn chirps twice. If you shut off the car open the door & hit the p0wer lock on the door it chirps once, after closing the door it chirps 9 yes 9 times. I have searched for a way to change the settings & have not been successful. Any help would be appreciated, it is a little annoying
