Program the Transponder (if appropriate)
- Connect the key developer to the OBD‑II port. Follow the on‑screen prompts to "learn" the new key to the immobilizer system.
Test Remote Functions (if equipped)
- Verify lock/unlock, trunk release, and panic buttons. If cloning, use an RF duplicator to reproduce the rolling‑code signal.
Last Verification
- Place the duplicated key into the ignition and attempt to start the engine. Verify that all electronic features work as expected.
File and Label
