This disables your car honking when you lock or unlock the door(s). NOTE: The car still chirps, but no horn.
Turn the key over to ON (whole dash lights up) for 5 seconds and then turn it back one click to Accessories (radio on).
Under the dashboard, above the footwell there is a light that blinks when the car is locked and the alarm is armed. Behind that light is a button.
Press it three times. You will hear the chirp sound and then, FREEDOM for you and your neighbors!!!
