Heard the other day they can get into your car by using some dodgy program online, basically they will stand by your front door and use it to boost the signal from your key fob. If you leave it near the front of the house it will work and open your car. Crazy stuff. If your car is keyless they could then drive off with it, but generally they are just looking for stuff left in the car. Happened 2 doors up from me in Heath the other day, plod warning everyone not to leave car keys near front of house so they can’t bounce the signal.
