An FCC ID on a car key is the identification number assigned to the key’s remote transmitter by the Federal Communications Commission. It is used to show which wireless remote design and signal type the key uses.
If you are replacing a remote key, flip key, or smart key, the FCC ID is one of the most important details to match. Even if two keys look the same, they may use different electronics, frequencies, or button functions. Matching the correct FCC ID helps confirm that the replacement key is the right remote type for your vehicle.
Optional Additional Info (if helpful):
The FCC ID is usually printed on the back of the remote or inside the key shell. It is commonly used along with the vehicle year, make, model, frequency, and part number to verify compatibility.
