2024 Ford Explorer Key Fob Guide (US): Types, FCC IDs, Batteries, and Replacement Options

The 2024 Ford Explorer sold in the United States typically uses a proximity “Intelligent Access” smart key fob, and some trims/packages may also be paired with a Phone As A Key-style setup through FordPass. Replacement shopping can be confusing because Ford key shells can look similar while using different FCC IDs, frequencies, and emergency key styles. Consumers generally find the fastest path is to match the FCC ID and part number from an existing working key, then confirm feature support (especially remote start and liftgate). This page explains the common key fob options typically include for a 2024 Explorer, what to verify before buying, and what typical price ranges are in 2026.

Compatible Key Fob Types

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

Intelligent Access Smart Key (Proximity) – 5-Button

Most 2024 Ford Explorer trims in the US use a proximity smart key (Ford Intelligent Access). The fob communicates with the vehicle for push-button start and allows passive entry when the fob is nearby, while the physical emergency key inside the fob can unlock the door if the fob battery is dead.

Features

  • Proximity unlock/lock (Intelligent Access)
  • Push-button start (no key blade needed for starting)
  • Power liftgate control (when equipped)

Most 2024 Explorer proximity keys require diagnostic equipment to add a key to the vehicle’s immobilizer system. Some situations may require at least one working key already present; all-keys-lost cases can involve additional security steps and time.

⚠️ Common Issues

  • Wrong fob purchased because the FCC ID/part number doesn’t match (look-alike shells are common)
  • Intermittent passive entry or “No Key Detected” warnings due to weak CR2450 battery or signal interference

Intelligent Access Smart Key (Proximity) – 4-Button (No Remote Start Button)

Some Explorer configurations may use a similar proximity smart key without a dedicated remote-start button (remote start may be unavailable, app-based, or controlled differently depending on trim and options). The vehicle still uses proximity authentication for push-button start and passive entry when equipped.

Features

  • Proximity unlock/lock (when equipped)
  • Push-button start
  • Power liftgate control (when equipped)

🏢 Dealer Required

Like other Ford proximity keys on late-model vehicles, adding a key typically requires a scan tool-based procedure and security authorization. Features can vary by trim, so button layout should match the vehicle’s equipment.

⚠️ Common Issues

  • Buying a fob with remote start button for a vehicle that doesn’t support it (or vice versa), leading to nonfunctional buttons
  • Emergency key insert/profile mismatch (key may not physically fit the door cylinder)

Consumers generally find all-keys-lost situations cost more because additional security steps, towing, or extra labor time may apply.

đź›’ Buyer's Checklist

Before purchasing a replacement key fob for your 2024 Ford Explorer, verify these points:

1 Verify the FCC ID matches your current key (printed on the fob label or inside the shell)
2 Confirm the button layout matches your Explorer’s features (remote start, power liftgate, panic)
3 Match the emergency key style (insert key profile and length) to avoid a key that won’t cut or won’t fit
4 Check whether the listing is OEM, refurbished OEM, or aftermarket and confirm return terms for “opened/electronics” items
5 Confirm the fob is specified for the US market (frequency/compatibility can differ from Canada/other regions even when the shell looks identical)

⚠️ Common Mistakes to Avoid

âś—

Choosing a look-alike Ford smart key without matching FCC ID/IC and part number (results in a fob that cannot be added to the vehicle)

âś—

Assuming any remote-start button will work (remote start availability depends on trim, equipment, and vehicle configuration)

âś—

Replacing the fob when the issue is only the battery or a damaged emergency key insert

Frequently Asked Questions

Does the 2024 Ford Explorer use a smart key (proximity) or a standard metal key?

In the US market, the 2024 Ford Explorer is typically equipped with a proximity smart key for push-button start (Ford Intelligent Access), depending on trim and equipment. Even with a smart fob, there is usually an emergency key insert inside the fob for door access if the battery is dead.

What battery does a 2024 Ford Explorer key fob use?

Most 2024 Explorer proximity smart keys commonly use a CR2450 coin-cell battery. If the fob range drops or the vehicle displays a “Key Battery Low” message, replacing the battery is often the first thing consumers generally try before replacing the entire fob.

Can a 2024 Ford Explorer key fob be programmed at home?

For late-model Ford proximity keys, options typically include professional programming with diagnostic equipment rather than simple “on/off cycle” self-programming. Some vehicles require at least one already-working key to add another, and all-keys-lost cases typically require additional security authorization.

Will a used key fob work for a 2024 Ford Explorer?

Sometimes, but it depends on whether the specific fob can be successfully added to your vehicle and whether it has been previously locked to another vehicle’s security system. Consumers generally find that matching FCC ID/part number is necessary but not always sufficient; confirmation of reusability and return terms is important before buying used.

Why do some Explorer fobs look the same but not work?

Ford fobs can share the same exterior shell while using different internal electronics (FCC ID, frequency, and board type) and different emergency key inserts. Even small differences can prevent pairing or cause certain buttons (like liftgate or remote start) to be nonfunctional.
