A lot of higher end cars are now coming out with RF fobs that unlock and start the car. There is no longer a physical key that is inserted in the ignition. It turns out that for BMW this means stealing the cars is extremely easy for a sophisticated criminal. We always liked the idea of metal keys that ALSO had a chip in them. The two-tiered security system makes sense to us, and would have prevent (or at least slowed down) the recent rash of BMW thefts that are going on in the UK.

So here’s the deal. A device like the one seen above can be attached to the On-Board Diagnostic (ODB) port of the vehicle. It can then be used to program a new keyfob. This of course is a necessary feature to replace a lost or broken device, but it seems the criminals have figured out how to do it themselves. Now the only hard part is getting inside the car without setting off the alarm. According to this article there are ultrasonic sensors inside which are designed to detect intrusion and immobilize the vehicle. But that’s somehow being circumvented.

You can check out a keyfob programming demo, as well as actual theft footage, after the break.
