Car Alarms: chirp, valet mode, dash area

Question
I have a chapman C450 in a 96 avalon.  The unit alarm works when I tested by
opeining the doors but for some reason the chirp went away. When I lock or
unlock the car with the remote it locks but lacks the familiar chir chirp I am used
to hearing.  How can I re entergise the chirp.

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,
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.
