With the rise in carjackings in our area, does anyone have any good suggestions for some kind of engine immobilizer that can be installed?

I like Defender Ammunition's 9mm Hollow Point.

.357 Magnum hollow point

With carjackings sorry you should not be worried about your vehicle but life so I would say drive with a bulletproof vest. I live in one of the largest metro areas in the country and I can not even remember a local carjacking. Chicago averages 5 a day and Philly 3.5 a day. I would move. You must be in Seattle.

Focus on avoidance. Never buy gas anywhere after dark. Lots of carjackings occur at gas stations. If you can use Costco for gas - do it. No cash, no mini-mart, staffed with attendants, so no criminals hanging around. Stay out of large shopping malls.

Does the digital key option on this car have any disablement mode for anti-theft?

All good points.

Has anyone tried the IGLA anti-theft system? I have seen videos on youtube. This maybe something I am interested in but would like any feedback before I look further.
