2024 GMC Yukon Key Fob Guide (US): Types, Batteries, Programming & Costs

The 2024 GMC Yukon (US market) typically uses GM’s proximity “smart key” system, often paired with remote start and push-button start. Exact fob style and features can vary by trim and packages (and whether the vehicle has a traditional ignition or push-button start). Replacing or adding a fob usually requires pairing the remote and the vehicle’s immobilizer, which consumers generally find is easiest with a dealer or an automotive locksmith with GM-capable tools. Before buying any replacement, confirming the correct FCC ID/part number and frequency for your specific Yukon is critical to avoid compatibility and return issues.

Compatible Key Fob Types

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

Proximity Smart Key Fob (Push-Button Start)

A proximity (PEPS) smart key used for keyless entry and push-button start. When the fob is nearby, the Yukon can unlock via door-handle sensors (if equipped) and start with the start/stop button. This is the most common key style for many 2024 Yukon trims and packages.

Features

  • Proximity keyless entry (passive entry when near the vehicle, if equipped)
  • Push-button start (immobilizer-authenticated start)
  • Remote start (if equipped/active on the vehicle)

Programming

🏢 Dealer Required

Pairing typically requires a GM-capable scan tool and security access to program both the remote functions and the immobilizer portion. Some situations may allow an “add key” procedure when you already have working keys, but many owners still use a dealer or automotive locksmith due to security steps and model/trim variations. If all keys are lost, programming is typically more involved and may require proof of ownership and additional time.

⚠️ Common Issues

  • Wrong FCC ID/part number purchased (remote functions or proximity may not work)
  • Weak CR2032 battery causing intermittent detection or reduced range
  • Aftermarket shells/buttons not matching the original (liftgate/remote start icons differ)

Remote Keyless Entry (RKE) Flip/Integrated Key (If equipped)

Some configurations may use a remote with an integrated mechanical key blade (often a flip-style or integrated insert) for door access, paired with the vehicle’s immobilizer system. This is less common on push-button-start Yukons but may appear depending on configuration or fleet/option differences.

Features

  • Remote lock/unlock
  • Mechanical key access for the driver door
  • Alarm/panic function

Programming

🏢 Dealer Required

Programming typically includes syncing the remote and pairing the immobilizer transponder to the vehicle. If a cut key blade is involved, it must be cut to match your locks (and may require additional verification). Consumers generally find that confirming the exact remote style and whether a blade is required prevents ordering the wrong part.

⚠️ Common Issues

  • Blade style/profile mismatch or incorrect uncut key insert ordered
  • Remote pairs but immobilizer portion does not (vehicle won’t start)
  • Used/remanufactured fob previously locked to another vehicle

Emergency Mechanical Key Insert (Inside Smart Fob)

A small mechanical key stored inside many GM smart fobs. It’s intended for emergency entry if the fob battery is dead or the vehicle’s remote functions are unavailable. It generally does not replace the need for a programmed smart fob to start the vehicle.

Features

  • Physical door entry when the fob battery is dead
  • Works without a battery
  • Backup access option

This key insert typically only needs to be cut (if it’s being replaced). It does not usually provide immobilizer authorization by itself on push-button-start systems.

⚠️ Common Issues

  • Key insert not cut or cut incorrectly (won’t turn in the door lock)
  • Insert style mismatch with the fob shell
  • Owner unaware of the hidden door lock cylinder location/cover

Totals vary by region, key type, and whether you’re adding a spare or replacing all lost keys. Dealer pricing often bundles OEM parts and programming; locksmith pricing can be lower but depends on tool coverage and availability. Aftermarket pricing usually reflects the fob only—programming, cutting an emergency insert, and diagnostics are commonly extra.

đź›’ Buyer's Checklist

Before purchasing a replacement key fob for your 2024 GMC Yukon, verify these points:

1 Match the replacement to your original: verify FCC ID, GM part number, button layout, and whether it’s proximity (PEPS) vs standard remote.
2 Confirm your Yukon’s start type (push-button vs other) and features (remote start, power liftgate) so the button set matches.
3 Avoid “universal” claims: consumers generally find OEM or OEM-equivalent remotes with confirmed compatibility reduce returns.
4 If buying used/remanufactured, confirm it can be re-learned to a new vehicle and is not locked/blacklisted.
5 Budget for programming and (if applicable) cutting the emergency insert; the fob price is often only part of the total.

⚠️ Common Mistakes to Avoid

âś—

Buying a fob based only on appearance instead of FCC ID/part number and frequency.

âś—

Assuming a cheap aftermarket remote will support proximity and remote start the same way as OEM.

âś—

Waiting until all keys are lost (all-keys-lost situations are typically more expensive and time-consuming).

Frequently Asked Questions

What battery does a 2024 GMC Yukon key fob use?

Many 2024 GMC Yukon smart key fobs commonly use a CR2032 coin-cell battery. Battery type can vary by fob revision, so checking the marking inside the fob or the owner’s manual is the safest confirmation.

Can I program a 2024 GMC Yukon key fob myself?

Some owners can add a key in certain situations when at least one working, already-programmed key is available, but many 2024 Yukon setups require GM-capable programming tools and security access. Consumers generally find dealer or automotive-locksmith programming is the most reliable route, especially for proximity smart keys and all-keys-lost scenarios.

Will a used key fob work on a 2024 Yukon?

Sometimes, but it’s risky. Used fobs may be locked to the original vehicle, may not support re-learning, or may have worn buttons and weak performance. If considering used, consumers generally look for clear confirmation it can be reprogrammed to a different GM vehicle and matches the exact FCC ID/part number and button set.
