Good To Know

Q: Will this ignition lock switch set work with my existing immobilizer system? A: Compatibility with immobilizer or anti-theft systems can depend on model year and trim, so confirm before ordering. Some vehicles may require additional programming after installation.

Q: Are the keys already cut to match the cylinders? A: This set is supplied with keys matched to the included ignition and door lock cylinders, though a locksmith may still need to confirm fit for your specific Kia Optima.
