I think there are two ways on turning the chirp off, otherwise known as valet mode. First locate the kill or valet switch. I'm not too sure how to disarm it if u have a push button switch but i know if u have a toggle switch all u gotta do is first turn the key to the 2nd click. It's like right before the engine actually turns on. Click the toggle switch to the off position and now ur system is in valet mode.

The 2nd way is, while the doors are closed and alarm is armed, press the 2nd button and then the 1st button. Now your system should be in valet mode otherwise know as siren off.

Hope this helps!
