My BMW X5 (less than a year old) has been broken into twice recently. The second time I had definitely locked the car and both keys had been in faraday pouches. It seems that the people who clone the key signal can retain the information and repeatedly enter the car. All BMW tell me is that this is an industry wide problem and that I should use a wheel lock to prevent the car from being stolen. The alternative is to change the locks and keys at a cost of around £2000 + VAT. Is there any solution to this?
