An FCC ID helps you identify the radio transmitter used in a key fob. It is a useful starting point for finding a replacement, especially when you combine it with the key’s part number, button layout, blade style and vehicle equipment.

Where can I find the FCC ID for my key fob?

Look for an “FCC ID” marking on the back of your existing key, under its battery cover or on the internal case label. Copy the full code, including letters and numbers. Then search that code on UrbanX and compare the product photo and part number with the original key.

Can I look up an FCC ID online?

Yes. The FCC equipment-authorization search can identify a transmitter from its FCC ID. On a replacement-key listing, use the ID as one compatibility clue alongside the part number, year/model, key blade, button layout and ignition type. The FCC ID alone does not establish that a key’s blade or immobilizer programming matches your vehicle.

How do I identify a key when the old fob is missing?

Use our VIN key lookup to narrow the product choices. A vehicle-maker parts department or qualified automotive locksmith can confirm the required key part from the VIN and equipment configuration. Then compare the key type—remote head, transponder or proximity—and the buttons shown on the product page.

Frequently asked questions

Do two fobs with the same FCC ID always interchange?

They may use the same transmitter identification, but the complete key can still differ in blade, transponder, button functions or vehicle programming. Match the full key details before choosing a replacement.

Can I get a key fob with only a VIN?

The VIN is a strong first step. Select your vehicle in our lookup, then confirm the exact key part and equipment so the product you order matches your car.

What if I cannot read the FCC ID?

Start with the VIN, year, make, model, original key shape and button layout. Ask a parts department or automotive locksmith to confirm the key part, then shop the matching UrbanX listing.
