Car Alarms: after market auto alarm not going off, valet mode, dash area

Question
I have a Toyota Matrix w/c i purchased 2 yrs. ago w/c I just recently learned it
has an after market alarm system. After I recently had it oil changed, door lock
still works, panic alarm still works, but when you open the door while it is
supposed to be locked & secured, the alarm does not go off anymore. What will
I do to make it work again?

Answer
Should be no problem really.
It appears from your expaination, that the
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.

That should do it.
Let me know what happens.
