These are all the types of technologies that are either investigated or implemented. For something like a key fob, one tool is putting in a Faraday bag as a way to block the signal.
It's important to remember that the key fob was introduced in part to address the rise in the hot-wiring of keyed vehicles. We have been asked why we don't go back to a key. The key system was overcome because thieves realized that there was a way past it. When key fobs were first introduced, they did deter theft, but now people are finding a way past that.
When manufacturers find ways to reduce the ability for someone to capture the signal, what we're now seeing is that they just come right into your house, so we're seeing this rise in carjacking. I think we also have to be careful. If you make a vehicle totally impenetrable and you don't address the theft issue we have in this country, the crime problem, organized crime groups will then come into your house, which is also a very bad outcome here.
Again, I think we have to be careful around the technology. Solutions are out there and constantly being implemented and updated, but if you don't address the crime, it's not going to stop the theft.
