"Mine does not sound when you
"Mine does not sound when you turn the key on,not sure if all have it, but if yours does, you should have a sensor coming out of the block, close to one of your spark plugs,it usually has an orange wire . If you turn your key on, and short that orange lead to ground, your alarm should sound. Look under your dash area for a small buzzer, mine was about the size of a stack of about 6 quarters or so. The buzzer itself could go bad, as mine did, test it by connection both leads directly to the battery, if it is bad, just replace it with a 12V piezo buzzer from radio shack, much cheaper and it works."
