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.
Final Verification
- Place the duplicated key into the ignition and attempt to begin the engine. Confirm that all electronic features work as anticipated.
File and Label
