Don't leave your keys near the front of your house..

Essentially thieves have now got a way of picking up the signal from the key inside the house using a very sensitive 'dish' and then transmitting it (or maybe just relaying it), at the car so that the car thinks the key is much nearer than it is. They then just get in and drive off!
I wouldn't have keyless on mine if you paid me. I wouldn't be surprised if insurers start asking if the car has keyless fitted.
