I bet a lot of wireless keys are insecure because someone's pointy-haired boss told an engineer it would be cheaper to implement the device by leaving out the challenge-response.

Untold Billions are probably lost every year by someone in charge ignoring something learned by freshmen undergrads.

The described attack would quite happily work even if there was a challenge-response system. It works by effectively extending the range of the key, automatically unlocking the car using the key even though the key is so far away the owner won't notice you stealing the car.
