If the shell is glued (common in some European brand names), it might require cautious cutting with an utility knife.Remove the Battery: Safely extract the battery and set it aside.Extract the PCB: Carefully lift the circuit board. It is crucial not to touch the metal parts with oily fingers or use pressure to the soldered chips.Phase 3: The Transponder Chip (Critical Step)
If the transponder chip is not integrated into the PCB, it is typically glued into a little pocket in the old shell. If this chip is not transferred to the brand-new shell, the car will not start. It needs to be gotten rid of with extreme care; if the glass case of the chip fractures, the key is completely handicapped.
Phase 4: ReassemblyPlace the PCB and the transponder chip into their respective slots in the brand-new shell.Set up the battery.The Blade Transfer: Most shells allow the initial metal blade to be swapped over by removing a small "roll pin."
