In locksmith terms
An FCC ID is an identifier the Federal Communications Commission assigns to a radio-transmitting device, including key fobs sold in the United States. It is printed on the back of most fobs, often as a short alphanumeric code following the letters FCC ID. Because a given fob design carries a specific FCC ID, that code helps narrow down which fob a vehicle uses.
It is an identification aid, not a complete spec. The same FCC ID can appear across multiple vehicles, and a single vehicle can have more than one compatible fob over its production run. We use the FCC ID alongside the year, make, model, and VIN to choose the correct fob, and we confirm the exact part rather than relying on the code alone.
In plain English
The FCC ID is the little code on the back of your fob. It is a clue that helps a locksmith figure out which fob you have, the way a model number helps identify a part.
It is useful, but it is not the whole story. We still confirm the right fob using your vehicle details, because the same code can show up on different cars and a car can accept more than one fob.
Why the number alone is not a guarantee
Relying only on an FCC ID can lead to ordering the wrong fob, because button counts, frequencies, and internal chips can vary even when the code matches. That is why a careful locksmith treats the FCC ID as one input and verifies the final choice against the vehicle. We never guess part numbers; we confirm them before cutting or ordering.
