check this immobilizer out
 

right here

looks good to me and if youre worried about those damn dirty thieves...this would ease your worries.

I think that I have something like that.

My friend has one of those.... it's awesone... Can't do shit without the mag key.

That's a really sweet idea. Looks very easy to build too..

Cool deal. A good anti-car jacking tool too, hop out of the car and mash the button in the process.....no car for you!

Any chance of interfering with the existing immobilizer that's in the car? Like, does the wiring have to be connected anywhere specific along the ignition system?

A kid I used to know had a '97 Civic with something like this. The guy who owned the car before him did some weird stuff with it. There was an immobilizer switch (that would trigger if the alarm went off) that was hidden back in the glove department. He also had a switch that could turn off his rear lights (running and brake). Kinda cool.
