The legal way would be someone developing cryptography hardware to calculate those prime RSA key. But, time it's the issue. Unless someone at factory left those keys in a CD or DME =)
They keys are available offline too for dealerships that are in areas that have no internet network as well as for dealers to use when systems are down. I have seen disks like this personally for BMW so I am sure they exist for MB.
