Car Alarms: PS-3175E no sound on lock., valet mode, shock sensor

Question
Hi

I have a PS-3175E installed on my car.
Until yesterday was ok. When i remote locked the doors i had a horn sound every time.

Now, is not working anymore.
Doors are locked but no sound. Even if i press two times the lock button.

What is strange, when i unlock the doors, the lights are flashing two times, pause, two times while the usermanual says: "The parking lights will flash twice"

Answer
It appears from your expaination, that the
after market car alarm is in service mode.

Ok, try this.
Put the key in the ignition, and turn forward
all the way just before cranking. Then within
5 seconds, press and hold in the valet/overide
button, found under the dash area, usually to the
left of the leg drilled into a hidden away spot,
until the installed LED (the blinking light)
in your dash area goes off, and the siren chirps twice.
(Your valet switch might be the toggle (on/off) type.
in this case, key on, flip switch in oposite direction,
key off.)

This should reset the alarm.

Just Repeat these steps to place it
back to valet mode.

(In valet mode, take the vehicle to a local
car alarm shop to evaluate the shock sensor
settings and if all componants are up to snuff.
Makes for a better experience.)

That should do it.
Let me know what happens.
