Car Alarms: Alarm System, chevy blazer, valet mode

Question
96' Chevy Blazer with Audiovox factyory installed system.  When I turn the lights on with the car in gear, the alarm goes off, but it is very muted, to the point that you can barely hear it from outside the car.  Turn the headlights off, or put the car in park, it stops.

Answer
Sounds like the system has a bad ground.
Check the siren first. May have water in it etc.
This would cause the low siren sound.

But try putting the system into
override mode so you can stop all the functions
until you can get to it.

For now, look under the dash area for a button or,
a toggle switch. When you locate it, turn on the
ignition key, press and hold in the button (little
spring loaded micro button, red or black possibly)
until the alarm chirps 1 time. This should over ride
the system, and only the keyless entry part,
if installed, would still be operating.
The LED (light emiting diode) light in the dash
should also go on solid.=VALET/OVERIDE
( if this is a remote starter, the antenna on the
front window glass may also have the over ride
button inset into it.)

This stops the alarm except for the keyless
entry if installed. Once in Valet mode,
it will allow the car to start and operate
like there was no alarm at all.

The next step is if wanting to remove it,
you contact a local technician to
locate it, and affect neccesary service
for you.

That should solve the troubles.

Let me know what you discover.
