LYFUCESS Smart Key Fob Replacement for Ford Mustang & Fusion (2017–2022) — 902MHz, Preinstalled Chip

A direct-fit aftermarket smart key fob replacement for Ford Mustang (2017–2022), Mustang Cobra (2019–2022) and Fusion (2017–2021) that supports 902MHz proximity keyless entry with preinstalled chip and battery.

This LYFUCESS replacement remote mirrors the button layout and electronic identifiers of the original Ford key fob (FCC ID: M3N-A2C93142600 / M3N-A2C931426) so you can restore keyless locking, unlocking and proximity functions without buying an OEM shell. Each unit ships with a tested transponder chip and battery already installed, but requires professional blade cutting and dealer or locksmith programming before it will start your vehicle. Read the compatibility details and programming steps below to confirm this fob matches your vehicle’s part numbers and frequency.

Does this key fob fit my Ford model and year?

Check compatibility by matching the part numbers, FCC ID and frequency listed on your original key. This LYFUCESS fob was designed to be functionally equivalent to several factory replacements and fits specific Mustang and Fusion model years.

• Compatible models: Ford Fusion 2017–2021, Mustang 2017–2022, Mustang Cobra 2019–2022.
• Works with FCC IDs: M3N-A2C93142600 and M3N-A2C931426.
• Compatible part numbers: 164-R8149, 164-R8162, 164-R8275, 5929500, 5929505, 545584.
• Frequency requirement: 902 MHz — verify before ordering.

What steps are required to make the fob work with my car?

This is a ready-to-program replacement but it does not include dealer-level programming or blade cutting. A locksmith or Ford dealer must cut the uncut metal key blade and complete the vehicle programming to link the transponder chip to your car’s immobilizer.

• Have a professional cut the key blade to match your ignition or door locks.
• Bring the fob and vehicle to a locksmith or Ford dealer for programming — self-programming is not supported.
• Confirm the dealer or locksmith can program FCC ID M3N-A2C93142600 / M3N-A2C931426 on 902MHz systems.
• Test all functions (lock, unlock, panic, proximity) after programming.

How does this LYFUCESS fob compare to an OEM key?

This replacement supplies the same electronic identifiers and preinstalled components but is sold without Ford branding. Materials and internal electronics are selected to match function and reliability, though it’s not an official OEM product.

• Includes preinstalled transponder chip and battery for immediate testing after programming.
• No Ford logos or OEM packaging — aftermarket alternative built to compatible specifications.
• Each unit is tested before shipping to ensure signal frequency and chip integrity.
• Requires professional services (cutting and programming) similar to OEM replacements.

Who is this for: The LYFUCESS smart key fob replacement is intended for Ford owners and automotive locksmiths who need a cost-effective, compatible remote to replace a lost, damaged, or worn factory key fob. It’s a practical option for vehicle owners who can arrange professional blade cutting and dealer or locksmith programming and who want a tested, ready-to-program unit matching Ford FCC IDs and part numbers without paying OEM prices.
