Keyless Security

There has been a lot of talk in the press and on TV in the UK about Cars, especially Range Rovers, BWWs and Audis, being stolen by people being able to program the keyless fobs and gain access to the car and drive it away, to the extent that some people in London were finding it hard to get insurance unless they had underground parking. On TV they specifically mentioned X5s. Does anyone know if this applies to X3s as well
