Lets take this one bit at a time, read carefully and please give me very specific answers as you are all over the place with this. Solving this is a _NON_ issue that you are turning into a big deal then placing blame on others.

What is back ordered, the complete flip key or the clipped head pocked key?

The key blank you got, is this to replace the one in the flip key or is this a clipped head pocket key that the dealer sent away for after taking your VIN and ownership information?

The "chip" is in the flip key housing. If you change the metal blade, the chip will still work. If the plastic housing fell apart, Google PCF7935 and look to see if this is laying around somewhere. This is the RFID "chip" required to trigger the anti theft, it is about 3/8" long and 3/16" tall / thick .

If you got a clipped head pocket key _PROGRAMMED SPECIFIC TO YOUR VIN_ , it will work right away.

If this is a clipped head pocket key that wasn't _PROGRAMMED SPECIFIC TO YOUR VIN_ , putting the old flip key next to the new key while cranking will run the car. If this is the case, get another ignition antenna ring ( same as similar year S, C and E class + probably more ) , tape the flip key ( or just the chip ) inside the antenna, plug it into the DAS box ( left under dash, follow the wire from the existing antenna ring. this will now run the car.
