Cut the blade-- For mechanical secrets, a key‑cutting machine copies the bitting pattern; for transponder/fob secrets, the exact same cutter is used, but precision matters more. Program the electronic part-- This action may include:- Immobilizer relearn: Connecting a diagnostic tool (e.g., OBDII Scanner) to the car's ECU to synchronize the new transponder. Rolling‑code sync (remote/fob): Using a special developer that clones the current remote's signal. Smart‑key pairing: Often requires dealer‑level software application or a licensed "key‑by‑code" service.
