These source-listed applications cover different years, products, and equipment alternatives. They are candidates for identification, not a single specification for every Sonata. Confirm the VIN, market, trim, build date, installed equipment, and key label before ordering.
Years use the US catalog selection window. Source ranges can include other markets; only their overlap with selectable years is grouped below. Missing years or references require individual identification and do not establish whether a vehicle has an immobilizer.

Separate entries are alternatives or overlapping source applications; do not combine them into one key. A part number, FCC ID, or frequency alone does not confirm compatibility, local stock, or service availability.
Select the exact model year to see its service details and referenced applications. The model name or year alone does not establish the installed immobilizer, key type, or programming method. Confirm the VIN, market, trim, and any replaced components against the source references and the vehicle.
