Plugged in the siren, and it beeps when I lock/unlock....but it won't beep like its supposed to when I "enter" the setup mode. I press the valet button for 3sec like the manual says and its supposed to chirp at me to confirm entering setup -- but nothing happens.

Stupid thing. I don't get it.

Here's how I have it though:
