3. The Transponder Chip
In some older or specific high-end models, the transponder chip is a little, different glass or carbon piece tucked into a corner of the shell. In more recent models, it is integrated directly onto the PCB.

It is vital not to touch the metal parts with oily fingers or apply 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 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 cracks, the key is permanently handicapped.
