Cut the blade-- For mechanical keys, a key‑cutting device copies the bitting pattern; for transponder/fob keys, the same cutter is used, but precision matters more. Program the electronic part-- This step 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 an unique developer that clones the current remote's signal. Smart‑key pairing: Often requires dealer‑level software or a certified "key‑by‑code" service.
Pro idea: Keep the original key convenient during programming; many vehicles need the master key to be present for the preliminary "discover" phase.
