Frankly, its worthless. But 90% of alarms usefulness is simply a deterrant so I don't care too much. I'm sure that little blinking light will keep it safe.
The OEM alarm is not a vibration alarm. I rather like this, some @$$ up the street from me has an alarm that will go off if a gnat farts.
As for the issue in the original post, do you own a helm manual? The alarm brain for EX is located behind the glove box. In the LX or DX or SE it was a dealer installed OEM option after the fact item.
