1. The Outer Shell: The plastic or composite real estate that secures the internal parts and provides the tactile buttons used for locking, opening, and trunk release.
2. The Printed Circuit Board (PCB): This is the "brain" of the key, including the microchips and battery contacts that send signals to the lorry.
3. The Transponder Chip: Often a tiny glass or ceramic tube, this chip communicates with the lorry's immobilizer system. Without it, the car might crank however will not start.
4. The Key Blade: The physical metal piece that is either repaired to the shell or integrated into a "flip" system.

5. Reassembly and Testing

Location the PCB, battery, and blade into the brand-new shell. Make sure all seals are seated properly to keep water resistance.
