Editorial scope
KeyFob Guide publishes editorial reference material for hobbyists, automotive locksmiths, and DIY mechanics. Information is compiled from manufacturer datasheets (NXP, Texas Instruments, EM Microelectronic), the NHTSA vPIC vehicle database, the FCC ID public database, the OBD2 community immobilizer database, and the published vehicle-coverage lists provided by aftermarket programmer vendors (Autel, Xhorse, AutoProPAD/XTOOL, Topdon, Advanced Diagnostics, Abrites). We make every reasonable effort to verify accuracy but cannot guarantee that every field on every page is correct for every variant of every vehicle.
Vehicle-specific verification
Before purchasing any aftermarket key fob or attempting any pairing procedure, verify the FCC ID and transponder chip family against the OEM fob in your vehicle. Cross-reference the FCC ID with the FCC's public database (fcc.gov/oet) and confirm the chip family with a knowledgeable parts vendor or locksmith. Trust your own eyes on the existing fob over any third-party data, ours included.
Safety
Key fob and immobilizer programming involves your vehicle's electronic security systems. Do not attempt programming procedures while the vehicle is in motion, on a public road, or in a configuration where an unintended start could cause injury. Always work in a well-ventilated, well-lit space with the parking brake engaged and the transmission in Park or Neutral.
Warranty implications
Aftermarket key fob installation may impact remaining manufacturer warranty coverage on certain immobilizer-related components, depending on the manufacturer and warranty terms. If your vehicle is still within its original factory warranty period, consult your warranty documentation or your dealer before proceeding.
Legal use
Key fob programming should only be performed on vehicles you own or have explicit authorization to service. Programming a key for a vehicle without authorization is unlawful in most jurisdictions. Automotive locksmiths in the United States are regulated at the state level — "key duplication," "key origination," and "all keys lost" services may require state licensure depending on where you operate.
