Car Alarms: 2001 Mercury Villager security alarm going off for no reason, mercury villager, ford factory


Question
My 2001 Village van security alarm seems to go off about an hour or so after I lock my car.  There does not seem to be anything which triggers it.  It only happens occasionally.  I cannot seem to find any pattern for why it happens.

I tend to turn off my engine, turn off my lights, etc, then open my door, and lock it using the door switch.  

I have several questions:
Why might this be happening?
Can I disable the alarm system completely?  It seems useless to have it.
If I disable it, will the car doors still lock?  Will I still be able to use my remote key fob to open the doors?

Thank-you for any information.

Answer
FORD FACTORY ALARM DISARM SOLUTION

There are a couple of ways to look at this issue.
If it's the OEM FACTORY alarm (ie; horn honk, headlights),
then the FACTORY ALARM DISARM WIRE is a dark
green/purple wire |-|, Located in the drivers kick panel
area coming out of the door.

Once Located, splice into the wire with
a simular guage wire, and put it to
a solid chassis ground. This terminates
the alarm functions entirely.

However, at this point, this car would be exceedingly
easy to steel, so I suggest you get an aftermarket
alarm system to protect it from here on in.

Speaking about that probability,
your 2nd option is...

If this IS an aftermarket alarm we are dealing with,
(parking lights flash, siren and an LED
blinking light in the dash), then try this....

...Put the key in the ignition, and turn forward
all the way just before cranking. Then within
5 seconds, locate, press and hold in the
valet/overide button, usually found under the
dash area to the left of the knee,
(push button, spring loaded)
until the installed LED (the blinking light)
in your dash area goes on solid,
and the siren chirps once.

(Your valet switch might be the toggle
(on/off) type. in this case, key on,
flip switch in opposite direction,
then turn the key off.)

This should reset the alarm, and reset
the grounded relay on the starter wire,
allowing you to start the engine.

At this point, the only thing working would
be the keyless entry from the alarm,
if it came equipped that way.

Just Repeat these steps to place it
back to usable armed mode.
You may get 2 chirps, confirming it,
and the lights may flash twice as well.

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
(Go to: www.vehiclewires.com)
for the vehicle, and reverse engineer it wire
by wire, until safely removed.

Let me know what happens.
