How can I prevent the hood opening from the outside?

[kognition]

I think LoJack works by triangulation using 3 outfitted vehicles, usually police cars. The system tells you whether your cold or hot, and which car is closest.

Car hood sensor is a good idea. Or just set up your ecu for easy removal. Lots
of ways to foil a thief.

So if you're in an area with poor reception.. you might not find your car.
