Aichiyu Smart Key Fob Replacement for Ford Escape/Focus/C‑Max — 315MHz ID83, 5‑Button

This aftermarket key fob replicates the original Ford smart remote configuration used on many 2012–2017 models. It ships complete with battery, ID83 transponder chip, internal circuit board and an uncut emergency metal key. The housing matches the original five-button layout—remote start, lock, unlock, trunk release and panic—so it looks and operates like the factory unit once an automotive locksmith or dealership performs diagnostic programming and blade cutting.

How do I confirm this fob will replace my existing Ford key?

Check the FCC ID and part numbers on your current remote before ordering. You must match FCC ID M3N5WY8609 or one of the listed part numbers to ensure compatibility with this Aichiyu replacement.

• Remove the emergency blade from your original remote to view the markings on the case bottom.
• Confirm FCC ID: M3N5WY8609 or P/N: 164-R7995 / 164R7995 / CJ5T-15K601-Dx.
• Also verify your vehicle model and year against the supported list (Escape, Focus, C‑Max, Maverick where specified).

What steps are required to get the new remote working with my car?

This replacement requires professional diagnostic programming and a key cut; it cannot be self-programmed at home. A local automotive locksmith can usually program the transponder and cut the emergency blade, often faster and less costly than a dealer visit.

• Have the locksmith perform transponder registration using OBD diagnostics.
• Provide the uncut emergency key to be cut to your vehicle’s key blank and code.
• Confirm all remote functions—lock, unlock, trunk, remote start and panic—after programming.

Which vehicles and features does this Aichiyu remote support?

This fob is designed for multiple Ford models across model years listed; it carries the correct 315MHz frequency and ID83 chip used by those vehicles. It preserves the original five-button control layout and includes the battery and internal components so the remote arrives ready for programming.

• Compatible models include Ford Escape Titanium (2013–2016), Escape (2017), Focus SE/Titanium (2013–2016, 2017), C‑Max Energy (2013–2017), Focus BEV Electric (2012–2017).
• Makes use of FCC ID M3N5WY8609 and P/N CJ5T-15K601-Dx variants.
• Includes battery, ID83 chip, circuit board and uncut emergency key in one complete unit.

What should I verify before purchasing to avoid returns or mismatches?

Confirm the button configuration, FCC ID and part number exactly match your original remote. Check the listed vehicle fitment and remember that programming and blade cutting are not included with the purchase.

• Ensure your original remote displays the same five-button layout (remote start, lock, unlock, trunk, panic).
• Match FCC ID/PART NUMBER on your existing key to the product listing.
• Plan for locksmith or dealer programming and emergency key cutting after receiving the fob.
