Car Alarms: Valet mode toggle switch wont disengage alarm., mercury grand marquis, valet mode

Question
I own a 1996 Mercury Grand Marquis and the valet mode toggle switch will not disengage the alarm.  I know the starter and the ignition system are in good working condition.  I am not sure whether it is a factory or aftermarket alarm system as I am not the original owner of the car.  What, if anything, can I do to disable the alarm?

Answer
Humor me a sec.
  Was it in a certain sequence with
this valet switch you found?

Turn on the ignition
key, press and hold in the button (little
spring loaded micro button, red or black possibly)
until the alarm chirps 1 time. This should over ride
the system, and only the keyless entry part,
if installed, would still be operating.
The LED (light emiting diode) light in the dash
should also go on solid.

At this point. the alarm would have reset.
If this had a starter kill relay installed,
it would now be opened, and the engine would
turn over when tried.

You would repeat these steps to go back to
user mode to see if this was corrected.

Let me know if it works for yours.
