I fondly remember back in the 1960's when my roomate bought a Honda 90
and was worried that someone might steal it. He actually did that for a
couple of nights though there was no Glock available. (Provided service
revolvers were locked away to prevent mischief). Quite a feat
considering that we lived on the third floor of a high rise...

Like I said in another post, I don't think they're after cars, they're
after wallets, electronics, etc. They've been into almost 100 cars in the
last three months.

I want to hear it so I can have them meet my Louisville Slugger...

It ain't the car I'm worried about...it was $150 (but it is a NICE car!)

I'm more worried about the JVC MP3 player and my *new* XM Receiver!

Why not just have a scr trigger from the interior light?
The scr will switch the horn relay to ground.
Door opens, light switch fires SCR, horn blows until someone turns off
the hidden (under dashboard or seat) switch, which breaks the circuit to
SCR. You could use a capacitor to give you a few seconds to leave or
enter the car.
After thinking about it, you may have to use a transistor to invert the
signal from the door switch. You could set up your delay with the
capacitor, resistor, to wait 10 or so seconds before firing the
transistor, which would then set the scr.
Back in the 70's when the price of gas was rocketing, people stealing
gas from your car at night became a common occurance.
I thought about attaching a small magnetic reed switch to the gas cap
cover that would do the same thing. Just never got around to doing it.
One guy I know wired a 120 volt hot wire to the frame of his car. I
wouldnt recommend doing this though, it could kill someone and give you
a manslaughter charge.
(I know, it shouldnt be against the law to kill a thief, but it is.)

All I want is something that will blow the horn, and maybe flash the
lights.

In it's simplest form, a switch mounted somewhere outside the car that
turns the system 'on' by providing a ground path for a relay. When someone
opens a door, the relay closes, current is passed to a flasher (like for
your turn signals) and then to the horn and headlight relays. Very simple.

Also, this is instantaneous. As soon as they open the door, the horn
starts. There is an 'always on' current source (courtesy lights) that do
not turn off when the dome light is turned off, so I intend to use this
for the 'trigger'.

Because this would blow the horn when *I* open the door. I leave at 1AM.
But I don't want a delay. A key switch with a cover outside would solve
this.
