Keymall replacement shell is a drop-in exterior case for Ford F150/F250 2015–2017 5-button remotes that lets you reuse your original electronics and key internals.

If your Ford key fob has a cracked housing, worn buttons, or cosmetic damage but the electronics still work, replacing only the shell is a fast, cost-effective fix. This Keymall product is a blank outer case sized for FCC ID M3N-A2C31243300 / P/N 164-R8117 and designed to accept the original circuit board, battery, and mechanical key — no reprogramming required.

Will this shell fit my Ford key fob?

Compare the FCC ID and button layout on your current remote to confirm compatibility: this case is made specifically for FCC ID M3N-A2C31243300 (P/N 164-R8117) five-button Ford remotes. It matches the lock, unlock, remote start, trunk and panic button configuration used on F150 and F250 models in the 2015–2017 model years.

How do I install the Keymall replacement shell?

Installation requires transferring the electronics and key blade from your old fob into the new Keymall housing; there is no need to reprogram the remote after swapping components. You will need to carefully open the original fob, seat the circuit board and battery into the new shell, and have the metal key cut if you require a new blank.

• No electronics, transponder chip, or battery included — shell only
• Remove internal circuit board and components from original remote and insert into new case
• If battery compartment is tight, try a thinner CR2025 battery for easier closure
• Get the key blade cut and fitted by a qualified locksmith if necessary

What should I expect in terms of materials and finish?

The Keymall shell comes in a predominantly black housing with silver accents that replicate the factory look of your Ford remote. The case is an economical exterior replacement built to restore appearance and button responsiveness but it does not include internal electronics or a pre-cut key blade.

• Main color: black with silver trim for OEM-like styling
• Durable plastic construction meant to protect existing electronics
• Button pads and exterior features positioned to match original fob
• Sold as a single key fob shell in the package

Can I avoid buying a whole new fob by using this shell?

Yes — if the original remote’s electronics and transponder are functioning, replacing just the exterior shell is a budget-friendly option that preserves your existing programming. This approach saves the cost of a new full fob and avoids dealer reprogramming fees, provided you correctly transfer and reseal the internal components.

• Cost-effective alternative to full remote replacement
• No reprogramming required when reusing original electronics
• Best for remotes with working circuitry but damaged housing or buttons
• Ensure correct FCC ID and button pattern before purchase

Who is this for: The Keymall remote key fob shell is ideal for Ford F150 and F250 owners (2015–2017) whose key electronics still function but whose outer case is cracked, scuffed, or has non-responsive buttons. It’s also suited for DIYers and locksmiths who can transfer the circuit board, battery and key blade into a new housing and want a clean, OEM-style replacement without paying for an entirely new programmed fob.
