If the shell is glued (common in some European brand names), it may require careful cutting with an utility knife.Get rid of 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 components 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 typically glued into a small pocket in the old shell.
