Hi all,
The keys I received with my '04 S4 are looking a bit crappy & overused, and on one of the keys the flip-blade isn't "flipping" properly.
I was wondering whether it's possible to completely disassemble the key, such that I could buy a replacement fob, and put all of the essential parts from my key into it.
Would it be as simple as putting in the circuit board and battery, and swapping the key blade, or are there any other essential parts which identify my key to the car? I have seen pictures of little cylindrical transponders, but can't see one of these in my key.
