Bought a key off ebay with an A1 case (the case of my regular key is badly cracked and on the verge of disintegrating); how do I get the circuit boards out of the key cases so I can put mine into the good case?
 
Watch this video… YouTube - How to change Mercedes-Benz key battery … then remove the batteries holder.
As your existing case is in very poor condition you can get a nail clippers or similar and slowly cut the old fob to pieces, bit by bit until the circuit board comes free of the casing.

Doing it this way will give you an insight into how the circuit board comes out of the old broken case and how it fits into the new case.
