Extract the PCB: Carefully lift the circuit board. It is crucial not to touch the metal components with oily fingers or use pressure to the soldered chips. Phase 3: The Transponder Chip (Critical Step) If the transponder chip is not incorporated into the PCB, it is frequently glued into a little pocket in the old shell. If this chip is not moved to the new shell, the car will not start. It needs to be eliminated with severe care; if the glass housing of the chip fractures, the key is completely disabled.
