FCC ID Lookup

The FCC ID is printed on the back of your key fob. Click a code below for vehicle compatibility, programming requirements, and replacement options.

What the FCC ID actually tells you

The FCC ID printed on the back of every car key fob is a U.S. Federal Communications Commission registration that identifies the radio profile of the wireless transmitter inside the fob. The profile defines the transmit frequency (typically 315 MHz in North America), the modulation type (most commonly ASK or FSK), the maximum power output, and the duty cycle. Two fobs that share an FCC ID share that radio profile. Two fobs with different FCC IDs may not work on the same vehicle even if they look identical from the outside.

How to find the FCC ID on your fob

The FCC ID is printed in small text on the back of the fob, typically near the battery compartment, sometimes under a sticker that has to be peeled back to read. The format is letters followed by digits, for example M3N-A2C931426 or HYQ14FBA. The label is not always immediately obvious. If you cannot find it, open the fob carefully and check the inside surfaces; some manufacturers print the FCC ID on the inside of the battery cover.

Why we organize replacement guidance by FCC ID instead of by vehicle

Manufacturers frequently ship multiple FCC IDs across the same model year for trim or production variations. A 2018 Ford F-150 might use M3N-A2C931426 on some trims and a related variant on others. Organizing replacement guidance by the FCC ID on the back of the fob is more reliable than organizing strictly by year and trim because the FCC ID is what determines compatibility at the radio level. We still document the typical vehicle compatibility for each FCC ID, but the FCC ID is the definitive identifier.

What the chip inside the fob is, separate from the FCC ID

The chip inside the fob handles cryptographic authentication with the vehicle's immobilizer module. The chip is separate from the radio module that the FCC ID identifies. Common chip families include Hitag2 (older), Hitag Pro (mid-cycle), Hitag AES (current generation), Texas Crypto 4D60 / 4D63 / 4D67 / 4D68 (Ford PATS, Toyota IMMO), and Philips Crypto 2 / Crypto 3 (Honda ID46, ID47). Two fobs with the same FCC ID may use different chip families if the FCC ID has been carried across multiple chip family transitions. The chip family determines what programmer protocol the technician needs.

What customers should expect on a mobile dispatch

Mobile dispatch follows a consistent sequence. The technician arrives with the correct equipment for the work confirmed on the phone, verifies customer identification against the vehicle paperwork, performs the work, runs the verification cycle, and collects payment on completion. There are no add-on charges after arrival except for legitimate add-ons explained and confirmed in advance, such as replacing a worn ignition cylinder discovered during inspection.

When to call before the situation becomes an emergency

Spare key service is the single most useful preventive step for any vehicle owner. With a working key as the programmer's authentication seed, a spare is a short on-site job. Without any working key, the programmer must first read the immobilizer PIN from the vehicle, which adds time and complexity. The same working key result in both cases, achieved through a longer process when starting from zero.

The internal index structure of the FCC database

The database is organized alphabetically by FCC ID prefix. Each FCC ID page documents the radio profile, the typical vehicle compatibility by year and make, the chip family inside the fob, the typical button layout, the emergency mechanical blade pattern where applicable, the programming protocol required to enroll the fob, and the common aftermarket pitfalls to watch for when ordering replacement fobs from marketplace sources.

What to do if your FCC ID is not in the index

The database covers the most requested FCC IDs in the service area. If yours is not listed, the underlying technology likely follows the same pattern as the documented FCC IDs in the same general category. Call with the FCC ID printed on your existing fob, plus the year, make, model, and VIN of your vehicle, and we will confirm whether we stock the matching fob and what programming the job will require.

How aftermarket marketplace pitfalls work

Marketplace listings for replacement fobs are inconsistent in quality. A listing that uses the correct FCC ID label may still ship a fob with a clone chip that passes initial programming and then fails authentication weeks later as the immobilizer rolling code drifts. A listing for a fob with a similar but different FCC ID may not pair with the target vehicle at all. The reliable approach is to order OEM equivalent fobs from major suppliers with documented chip family information, or to let the mobile service source the fob as part of the dispatch.
