Car Alarms: 1997 for explorer... alarm.., valet mode, mechanic friend

Question
hi... our family car is a 97 ford explorer, whats happening is that there is a "silent" alarm... so when the truck sits for a couple minutes this alarm activates and a little red light blinks, once this alarm is active it will not turn over untill the alarm is disabled with the remote. when the alarm goes off it wil just blink the break lights and turning signals (no sound). until recently its been working fine but a week ago the remote didnt work! we tried replacing the remote battery but it didnt work. we talked to a mechanic friend and he taught us a trick to bypass the alarm by turning the key half way, unhooking the battery for a little while, and rehooking it, and starting the car. it worked pretty good and after that the remote started  working again. well this morning it happend again, but this time the remote still wont work even after reseting the whole thing... i was just wondering if you knew what the problem was n how we can fix this for good... thanx in advance!!!

Answer
Sounds as if the installer did not put in a siren.

To start, look under the dash area for a button or,
a toggle switch. When you locate it, 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.=VALET/OVERIDE

This stops the alarm except for the keyless
entry if installed. The next step is to
either remove the alarm or, try to identify,
and get new remotes for it.

But once in Valet mode, it will allow the car
to start and operate like there was no
alarm at all. Repeat steps to put into user
mode.

Let me know how it goes.
