Thieves Are Boosting the Signal From Key Fobs Inside Homes To Steal Vehicles (www.cbc.ca)
An anonymous reader quotes a report from CBC.ca: According to Markham automotive security specialist Jeff Bates, owner of Lockdown Security, wireless key fobs have a role to play in many recent car thefts, with thieves intercepting and rerouting their signals -- even from inside homes -- to open and steal cars. According to Bates, many of these thieves are using a method called "relay theft." Key fobs are constantly broadcasting a signal that communicates with a specific vehicle, he said, and when it comes into a close enough range, the vehicle will open and start. The thief will bring a device close to the home's door, close to where most keys are sitting, to boost the fob's signal. They leave another device near the vehicle, which receives the signal and opens the car. Many people don't realize it, Bates said, but the thieves don't need the fob in the car to drive it away. Bates says, if you have a key fob that can wirelessly unlock/start your car, you should not keep it by the front door.
"If you do live in a house, try to leave your keys either upstairs or ... as far away from the vehicle as possible," he said. "The other thing that you can do is there are products out there that you can put your key fob into," such as a faraday cage -- a box used to block radio signals -- a key pouch, which works similarly, or even a steel box.

The mechanism in a fob that lets the vehicle start is not the same mechanism that operates the locks. Additionally there's different programming needed to add the convenience controls versus programming the fob to where the vehicle will start with it.
This "hack" was possibly demonstrated on an old Top Gear when one of the presenter's cars was moved into the street by another presenter while they were at a restaurant. Basically supposedly it was close enough that the the fob and car could communicate. Given that this was for entertainment it's difficult to say if it was real or not.
Either way though, I guess I'm still a fan of having a physical key that must be inserted into a slot, used in combination with an immobilization system that communicates with a chip that's embedded with the key.
Do not look into laser with remaining eye.
...car theft. Once autonomous cars are perfected, thieves can remotely start the target car and have it drive itself into a Faraday caged trailer. The vehicle pulling the trailer will be autonomous too.
