Here's the "buzzer" mode info:
BUZZER OPERATION MODE
The factory setting for the buzzer mode is buzzer ON. Selecting the buzzer OFF mode only affects the buzzer operation during remote arming & disarming.
NOTE: Power loss to the system (e.g. due to a dead battery in the vehicle) has no effect on the operation of these or any other features.
To change the buzzer operation mode, follow the steps below:
1) Sit in the driver seat with all doors and the tailgate window closedl
2)Press and release the remote control's top button once to lock the doors, then once again to inlock the driver door only.
3) Open the driver door only.
4) Insert the key into the ignition switch, and turn it to "ON" (not "ACC) 5 times (LOCK > ON > OFF > ON > OFF > ON > OFF > ON > OFF > ON) within a 10 second period.

* THe vehicle's marker lights and parking lights flash once.
