Adding a Factory Alarm Unit.
I added a factory
keyless alarm system in December, 1997, which I purchased from The BMW Store in Cincinnatti,
OH. This job is a little more complicated than the CD player
install, but is still well within the capabilities of a weekend
DIYer. Don't be scared off by the advertisements that recommend
installation by a professional -- it's not that hard. However, it
does involve drilling two holes into plastic parts, so be sure you have
the correct size drill bits handy. One hole is for the sound sensor
on the underside of the dash cowling (below the glove box), and the other
is for the LED "on" light, which is goes into the blank black plastic
filler panel that sits next to the ASC-T switch, just above the gear
shift. Other skills include minor disassembly of the dash, including
removal of the OBC and sunglass holder, cutting away of some insulation
that's glued to the back side of the dash cowling, and bolting in a siren
in the engine compartment. No need to run any wires, because they're
all already there.
Finding the connector that plugs into the control box took a few
minutes -- the drawing in the instructions was a bit vague, but after
studying it closely I managed to find the right connector wedged up behind
the glove box area taped to some other wiring. With the exception of
that one hard-to-follow drawing, the instructions that came with the unit
are quite complete and easy to follow. The entire job took me about
two hours.
Here is a link to the Unofficial BMW page
that has comments from others who have installed alarms in their
cars.
I like the alarm system in general, except
for the way it works if you arm the system and then use your key to unlock
the door. As soon as you open the door the alarm sounds. The instructions
say that there's a 5 second delay, but actually it's much less than
that. I would have preferred a 10-second delay, or better yet, for
the system to disarm when the door is unlocked manually.
