Car Alarms: pursuit alarm, dash area, button spring

Question
I just got a 1997 bmw 5 seies which has a pursuit alarm on it.
Not sure if it was originally in the car or after. The remote isn't turning the alarm off(battery in it works) so when i unlock the door the alarm goes off and car starter is disabled.Need to get it moving so as to have it taken out.
Any advice.Thanks

Answer
The alarm seems to be in long tamper mode.
You will need to reset, and possibly
re program the remotes. That part you will need
your manual for, but the aftermarket alarm
seems to be doing it's job.
At least we know it's installed correctly
which is actually a good thing here.

Ok, 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, found under the
dash area, (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 are looking to
get the remotes reprogrammed, try my site
at www.installsupport.com to see if my tech
there can assist. I don't do much in
Audiovox these days (persuit) However,

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.

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. Don't want to
get stuck in another bad situation.

Let me know what happens.
