Car Alarms: 2003 expedition remote start, valet mode, dash area

Question
I have a 2003 ford expedition with a factory installed remote start. I Just bought it used and the remote was working fine. Now when I go to use it, the horn chirps twice and nothing happens. Before it chirps once and the truck starts right up. Do I need to reset somnething or do tyou think it need to be reprogramed,and if so is it something I can do?

Answer
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.
If you want to remove it at this point,
take it to your neighborhood installer
for this, or buy the wiring chart for
the vehicle, and reverse engineer it wire
by wire, until it's safely removed.

If it does not work out this way, you will have
to replace the system with one you know how
to operate and what to expect.

Let me know what happens.
