2024 Ford Bronco Key Fob Guide (US): Types, FCC IDs, Costs & Compatibility

The 2024 Ford Bronco can use more than one style of key, depending on trim and options like Intelligent Access and remote start. The most important details when replacing a Bronco key fob are the FCC ID, frequency, and whether the vehicle uses a traditional turn-key ignition or push-button start. Consumers generally find that “looks the same” listings cause the most problems—especially when the FCC ID or key blade style doesn’t match. Options typically include OEM keys, refurbished OEM keys, and aftermarket replacements, each with different tradeoffs in cost and reliability.

Compatible Key Fob Types

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

Intelligent Access Smart Key (Push-Button Start)

This is the proximity-based smart key used on Broncos equipped with push-button start (Intelligent Access). It allows the vehicle to detect the key nearby for passive entry and starting, and it also includes remote buttons for functions like lock/unlock and panic. Some trims/packages may also include remote start on the fob, while others rely on app-based remote functions or a separate remote-start configuration.

Features

  • Proximity entry (Intelligent Access) when near the vehicle
  • Push-button start authorization
  • Remote lock/unlock and panic (button layout varies by fob)

Buttons

Battery

Aftermarket $90-$220 Programming separate

Programming

🏢 Dealer Required

Smart keys require pairing to the vehicle’s security/immobilizer system and typically cannot be added without professional diagnostic equipment and security access. Many situations also require at least one working key present; all-keys-lost cases are usually more involved.

⚠️ Common Issues

  • Bought the wrong FCC ID/part number for the specific Bronco build (buttons and electronics may not match)
  • Aftermarket shells with weak button pads or poor emergency-key fitment

Remote Head Key (Integrated Key + Remote, Turn-Key Ignition)

Some Broncos may be equipped with a traditional key ignition setup in certain configurations, using a remote head key (a physical key with integrated remote buttons). The remote controls door locks and panic, while the transponder chip inside the key is required for the immobilizer to allow the engine to start. The key blade style and transponder type must match the vehicle’s immobilizer system.

Features

  • Physical key blade for door/ignition
  • Integrated remote for lock/unlock (and sometimes remote start depending on configuration)
  • Immobilizer transponder required to start

Buttons

Aftermarket $60-$180 Programming separate

Programming

🏢 Dealer Required

Remote functions and the immobilizer transponder typically must be programmed to the vehicle. Some owners’ manuals describe limited on-board procedures for certain Ford remotes, but many late-model security systems still require diagnostic programming, especially for adding keys or all-keys-lost situations.

⚠️ Common Issues

  • Key blade cut/profile mismatch (key won’t turn or won’t cut correctly)
  • Remote works but the transponder is wrong, causing a no-start condition

Keyless Entry Keypad (Door Code) + Backup Key (Vehicle Feature, Not a Fob)

Many Broncos support Ford’s keyless entry keypad feature (either as a physical keypad or a keypad accessory), allowing entry using a factory door code even if the fob battery is weak. This doesn’t replace the immobilizer key requirement for starting, but it can reduce lockout risk. Owners often pair this with a backup programmed key stored safely.

Features

  • Unlock/lock using a code (when equipped)
  • Helps reduce lockout risk if the fob battery is dead
  • Works alongside smart key or remote key systems

Battery

Enabling or changing keypad features depends on equipment and configuration. The factory door code is typically provided with vehicle documentation or can be retrieved with authorized diagnostic access.

⚠️ Common Issues

  • Assuming the keypad can start the vehicle (it generally only controls entry/locking)
  • Not knowing the factory door code when a fob is lost

Typical price ranges are driven by key type (smart key vs remote head key), whether a cut emergency blade is needed, and whether it’s an all-keys-lost situation. Consumers generally find OEM keys cost more but reduce compatibility surprises, while aftermarket options can be cost-effective when the FCC ID/part number is an exact match.

đź›’ Buyer's Checklist

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

1 Verify the FCC ID matches your current key (or confirm the correct OEM part number using your VIN)
2 Confirm whether the Bronco has push-button start (Intelligent Access) or a traditional turn-key setup—this changes the key type entirely
3 Match the button layout and functions (remote start, tailgate, panic) to avoid missing features or non-working buttons
4 Check that an emergency key blade (and correct blade style) is included or can be transferred/cut for your vehicle
5 Avoid “universal” listings unless they explicitly state compatibility with the 2024 Bronco and the exact FCC ID/part number

⚠️ Common Mistakes to Avoid

âś—

Buying based on appearance instead of matching FCC ID/part number and frequency

âś—

Assuming remote start is always on the fob (some Broncos use app-based remote functions or different configurations)

âś—

Replacing only the shell when the internal board is damaged (or replacing electronics when only the shell is worn)

Frequently Asked Questions

Does the 2024 Ford Bronco use a smart key or a traditional key?

Both exist depending on trim and equipment. Broncos with Intelligent Access use a proximity smart key for push-button start, while other configurations may use a traditional key with an integrated remote and a transponder. Checking for a push-button start and matching the FCC ID/part number from an existing key are the most reliable ways to confirm.

Where is the FCC ID on a 2024 Bronco key fob?

The FCC ID is typically printed on a label inside the fob housing or on the back of the fob, depending on the design. It may require opening the fob to view, especially on some smart keys. Matching the FCC ID is a key consumer-protection step because similar-looking fobs can use different electronics.

What battery does a 2024 Ford Bronco key fob use?

Many Ford smart keys commonly use a CR2450 coin battery, while remote head keys often use a CR2032, but variations exist. The safest approach is to check the battery marking after opening the fob or confirm in the owner’s manual for the exact key style. Replacing the battery won’t erase programming, but it can resolve reduced range or intermittent detection.

Can a 2024 Bronco key fob be programmed without professional equipment?

In many cases, adding or replacing late-model Ford keys requires diagnostic programming and security access, especially for smart keys and all-keys-lost situations. Some Ford vehicles support limited on-board procedures for certain remotes, but consumers generally find that modern immobilizer requirements make professional programming common for 2024 models. The exact requirement depends on the key type and how many working keys are already available.

Is an aftermarket key fob safe to buy for a 2024 Ford Bronco?

Aftermarket keys can work when the FCC ID/part number, frequency, and key type are an exact match for the vehicle. The main risks are mismatched electronics, lower-quality button pads/shells, and incomplete listings that don’t specify the correct identifiers. Options typically include OEM, refurbished OEM, and aftermarket—checking return policies and verifying identifiers helps reduce costly mistakes.
