Cannot identify the correct replacement key fob for a 2013 Kia Forte because third-party keys with the same FCC ID have different internal PCBs and fail to program, and the original fob is too worn to read markings.

Existing key-fob listings rely on FCC IDs which are inconsistent; there is no reliable way to cross-reference PCB layouts or firmware versions to guarantee compatibility.
