Cut the blade-- For mechanical keys, a key‑cutting maker copies the bitting pattern; for transponder/fob keys, the same cutter is used, however accuracy 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 integrate the brand-new transponder. Rolling‑code sync (remote/fob): Using an unique developer that clones the existing remote's signal. Smart‑key pairing: Often needs dealer‑level software application or a licensed "key‑by‑code" service.
Pro suggestion: Keep the initial key handy throughout programming; numerous cars need the master key to be present for the preliminary "discover" phase.
