Keymall Replacement Key Fob Shell for Ford & Lincoln — 5-Button Black/Silver Empty Housing to Reuse Original Electronics

This Keymall replacement key fob shell is a drop-in exterior case for Ford and Lincoln 5-button remotes (FCC ID: M3N-A2C31243300, P/N: 164-R7989) that lets you reuse your original electronics and avoid buying a full fob.

If the plastic housing of your car remote is cracked, worn, or has failing buttons but the internal electronics still work, swapping the outer shell is an affordable fix. This Keymall product is supplied as an empty shell with five button slots—Lock, Unlock, Remote Start, Trunk, and Panic—and accepts the original circuit board, battery, and metal key blade from your existing fob. It’s finished in black and silver to match factory styling and fits specific Ford and Lincoln models listed below.

Will this shell fit my key and vehicle?

Confirming compatibility before purchase avoids fitment problems. Match the FCC ID and part number on your current remote to M3N-A2C31243300 / 164-R7989, and ensure your button layout matches the five-button configuration. The shell is made to the same shape as the OEM housing for those listed model years.

• Compatible vehicles: Ford Edge (2015–2017), Explorer (2016–2017), Fusion (2013–2016), Mustang (2015–2017)
• Compatible Lincolns: MKZ (2013–2016), MKC (2014–2016), MKX (2016–2019)
• Required match: same FCC/P/N and identical button arrangement

How do I install the Keymall key fob shell?

Installation involves transferring the internal parts from your old remote into the new Keymall case; no soldering or electronic work is needed. Carefully pry open your original fob, remove the circuit board, battery and metal key, then place them into the replacement shell and snap it closed. If the battery cover is tight after assembly, trying a thinner CR2025 battery can help the closure.

• Tools: small flat screwdriver or plastic pry tool to open the original case
• Steps: remove internals → insert into new shell → close firmly, then cut key blade if needed
• Note: you will need a locksmith to cut the metal key blade to match your vehicle

What is included and what’s NOT included?

The package contains one Keymall exterior key fob shell only; it is an empty housing and does not include electronics. The remote board, transponder chip, battery, and any internal components must come from your existing OEM fob. This keeps cost low while restoring appearance and button function when the internals are still good.

• Included: 1 x replacement empty key fob shell (black/silver)
• Not included: circuit board, transponder, battery, or pre-cut metal key blade
• Reminder: no reprogramming required if you transfer original electronics

How durable and accurate is the fit compared to an OEM case?

Keymall manufactures the shell to match OEM dimensions so your buttons and key blade align with factory tolerances. Materials are intended to resemble the original finish and resist everyday wear; however, final fit can depend on how precisely you transfer the internal parts. Inspect alignment after assembly and use a thin CR2025 battery if the cover is reluctant to close.

• Finish: black and silver exterior designed to mimic factory look
• Fit: manufactured to OEM-style shape for the listed Ford and Lincoln models
• Longevity: restores cosmetic and mechanical button feel if internals are intact

Who is this for: This replacement shell is ideal for vehicle owners who have functioning remote electronics but a broken or cosmetically damaged exterior case and want a cost-effective repair. It’s also suited to DIYers and locksmiths who prefer to reuse the original circuit board and transponder rather than buying a fully programmed fob. Before ordering, verify your remote’s FCC ID and button layout match the product listing to ensure correct fitment.
