These source-listed applications cover different years, products, and equipment alternatives. They are candidates for identification, not a single specification for every CTS. 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.
