2024 Ford F-150 Key Fob Guide (U.S.): Types, FCC IDs, Batteries, and Replacement Options

The 2024 Ford F-150 commonly uses Ford’s proximity “Intelligent Access” smart keys, and many trims also support remote start and tailgate functions from the fob. Replacement shopping can be confusing because multiple FCC IDs, button layouts, and frequency variants may exist depending on trim, package, and build. Consumers generally find the safest approach is to match the FCC ID and button configuration from an existing working key (or the vehicle’s documentation) before purchasing. Options typically include OEM keys, refurbished OEM keys, and compatible aftermarket keys—each with different costs and programming requirements.

Compatible Key Fob Types

The following key types are typically compatible with the 2024 Ford F-150. Compatibility varies by trim and options.

Intelligent Access Smart Key (Proximity Fob)

FCC ID: M3N-A2C93142600

A proximity-based smart key used for push-button start and passive entry. When the key is near the truck, the vehicle can authenticate it for unlocking and starting; the buttons still provide remote functions like lock/unlock and panic.

Features

  • Passive entry / proximity unlock
  • Push-button start (no key insertion)
  • Remote lock/unlock and panic (button-based)

Programming

🏢 Dealer Required

Most 2024 F-150 proximity keys require security/immobilizer pairing using professional diagnostic equipment; some trucks also require all keys present during programming. Remote-start capability may depend on the truck’s equipment and the exact fob variant.

⚠️ Common Issues

  • Wrong FCC ID or frequency variant leading to no programming/limited functions
  • Intermittent proximity detection due to weak CR2032 battery or internal antenna damage

Intelligent Access Smart Key (Proximity Fob w/ Tailgate Function)

FCC ID: M3N-A2C93142600

A proximity smart key variant that includes an additional tailgate-related button on some F-150 configurations. It works the same way as other Intelligent Access keys but adds a dedicated control that may only function if the truck is equipped for that feature.

Features

  • Passive entry / proximity unlock
  • Push-button start
  • Tailgate function button on supported trucks

Programming

🏢 Dealer Required

Even when the key programs successfully, the extra function button may not operate unless the fob’s part number and the truck’s options match. Matching your original button layout is typically important.

⚠️ Common Issues

  • Button layout mismatch (tailgate/remote-start functions not supported on the truck)
  • Aftermarket shell quality issues (buttons sticking or poor range)

Remote Keyless Entry (RKE) Fob (non-proximity, if equipped)

Some fleets or specific configurations may use a non-proximity remote for door locks and alarm functions while starting is handled by a separate key system. This type does not provide passive entry or push-button start by itself.

Features

  • Remote lock/unlock
  • Panic/alarm activation
  • May support remote start on compatible trucks

Programming

🏢 Dealer Required

Programming requirements vary widely by configuration; some remotes can be paired through vehicle menus, while others require security access. Confirm the exact system on the truck before buying.

⚠️ Common Issues

  • Buying an RKE remote when the truck actually uses a proximity smart key
  • Short range caused by weak battery or incorrect frequency

Typical price ranges are driven by whether the key is an OEM proximity smart key, whether an emergency key blade needs cutting, and whether immobilizer security access is required. Aftermarket keys can cost less up front, but consumers generally find compatibility and feature support (remote start/tailgate) varies more than with OEM.

đź›’ Buyer's Checklist

Before purchasing a replacement key fob for your 2024 Ford F-150, verify these points:

1 Verify the FCC ID matches your current key (printed on the fob label) and confirm the button layout matches exactly
2 Confirm the truck’s start system (push-button start/proximity vs. traditional key) before ordering
3 Check that the listing specifies compatibility with 2024 Ford F-150 (U.S.) and matches frequency and part number family where provided
4 Prefer new or refurbished OEM electronics for proximity keys; consumers generally find unknown-brand “universal” proximity fobs have higher mismatch risk
5 Plan for cutting (if an emergency blade is included) and immobilizer programming—these are typically separate from simply replacing the battery

⚠️ Common Mistakes to Avoid

âś—

Ordering based on appearance only instead of matching FCC ID, part number family, and button layout

âś—

Assuming any Ford proximity key will program to a 2024 F-150 (security systems and frequencies vary)

âś—

Replacing the fob because of poor range when the real issue is a weak CR2032 battery or damaged fob shell contacts

Frequently Asked Questions

Does a 2024 Ford F-150 key fob use a CR2032 battery?

Most 2024 Ford F-150 Intelligent Access proximity fobs use a CR2032 coin-cell battery. If the truck shows “Key Battery Low,” replacing the CR2032 typically restores range and proximity detection. If problems continue after a fresh battery, the issue may be the fob itself or the truck’s antennas.

Can a used OEM key fob be reprogrammed to a 2024 F-150?

Sometimes, but not always. Many late-model proximity smart keys can become “locked” to the original vehicle or may not support re-pairing depending on the exact part number and security system. Consumers generally find it’s important to confirm the key is reprogrammable for a 2024 F-150 before purchasing a used fob.

Why does my replacement fob lock/unlock but not remote start on my 2024 F-150?

Remote start can depend on both the truck’s equipment (remote-start capability enabled) and the exact fob variant/button configuration. A mismatched part number or incorrect fob type may still operate basic lock/unlock while failing to trigger remote start. Matching the original FCC ID and button layout is typically the best way to avoid partial-function issues.

Is key fob programming DIY on a 2024 Ford F-150?

For most 2024 F-150 proximity smart keys, programming typically requires professional security access and diagnostic tools rather than a simple DIY pairing sequence. Some non-proximity remotes on certain configurations may have simpler pairing methods, but requirements vary by build. Checking the owner’s manual and confirming the exact key system is recommended before buying a replacement.

What should be checked if the truck says “No Key Detected” but the fob battery is new?

Common causes include a damaged fob (water intrusion, cracked solder joints, worn battery contacts), interference, or an issue with the vehicle’s proximity antennas. Trying a second known-good key (if available) can help isolate whether the problem is the fob or the truck. If only one key exists, consumers generally find it’s safer to address the issue promptly to avoid being stranded.
