Lug Nut/Wheel Lock size
I'm no mechanic and haven't tried this, but this came up on a quick search. Any guess if it's for real? (And no worries on me starting a new side line of work.

Not sure I understand here, are you saying that the OE Mercedes locks, packaged in a black plastic box with a white and blue label actually are made by the contractors you mention?
Or are your dealer just selling the cheaper McCauley/McGard branded locks and saying they are the same as OE?
@miketc
There are several methods of removing locks, the first tried and easiest (wich often separates the cheaper locks from the high end) is to use a long socket (19-22mm)and a heavy sledge hammer, many cheaper locks have bad or thin hardened edges making the socket stick and removal is easy.
Drilling will also reveal bad hardening
The last resort is to weld a nut to the bolt, this will almost always work but can damage the wheel if not done properly.
Again, the OE locks are by far the hardest to enforce, McGard is no match this is why I am pretty confident that they are NOT the same, there is always a reason for something being cheap.

does one have to rebalance the wheels after installing these?
