2. The Internal Circuit Board (PCB)
This is the "brain" of the key. It consists of the remote-entry transmitter and, in numerous cases, the transponder chip that enables the engine to start.
3. The Transponder Chip
In some older or specific luxury designs, the transponder chip is a little, separate glass or carbon piece tucked into a corner of the shell. In more recent models, it is incorporated directly onto the PCB.
4. The Battery
Typically a CR2032 or similar lithium coin cell, providing power to the remote functions.
5. The Metal Blade
This is the physical part of the key that goes into the ignition or door lock. It might be a repaired blade or a "switchblade" (flip) style.

If the shell is glued (typical in some European brand names), it might need careful cutting with an energy knife.Eliminate the Battery: Safely draw out the battery and set it aside.Extract the PCB: Carefully raise the circuit board. It is important not to touch the metal elements with oily fingers or use pressure to the soldered chips.Stage 3: The Transponder Chip (Critical Step)
If the transponder chip is not incorporated into the PCB, it is frequently glued into a small pocket in the old shell. If this chip is not transferred to the new shell, the car will not start. It must be eliminated with extreme care; if the glass casing of the chip fractures, the key is permanently handicapped.
Phase 4: ReassemblyPlace the PCB and the transponder chip into their particular slots in the new shell.Install the battery.The Blade Transfer: Most shells permit the original metal blade to be swapped over by removing a little "roll pin."
