Car Alarms: Keyless remote, valet mode, 2004 ford taurus

Question
I have a 2004 Ford Taurus SES.  When I brought it came with a aftermarket keyless entry remote fob.  The only thing working on the fob is the keyless entry for the doors.  The trunk release button on the fob will not open the trunk, only a low chirp sounds when the trunk or alarm button is pressed. Is there any way to reset or reprogram this keyless fob.

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.
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.
